What TitleVitals is
Stop jumping between KDP Reports, Bookshelf, Author Central, Audible, and Amazon product pages.
Start here: TitleVitals connects to your own Amazon publishing pages through a Chrome extension. It never sees or stores your Amazon password, and it does not log in for you — you log in to Amazon yourself, in your own browser. It collects the numbers you can already see, then organizes them into a private dashboard. Install the extension, sign in to KDP and Author Central, run the first sync, and your catalog begins filling in.
TitleVitals brings the key Amazon signals for your catalog — sales, page reads, royalties, ranks, reviews, audiobooks, editions, and author-page coverage — into one dashboard.
The result: a single place to watch your whole catalog. Real numbers are shown as real; estimates are always labeled as estimates; and every figure tells you when it was last synced.
What it pulls together
- Sales and free downloads, by title and by format, for today / this month / this year / all time.
- KENP page-reads (Kindle Unlimited) with an estimated dollar value, clearly labeled as an estimate.
- Royalties, when you are on a plan that shows the dollar layer.
- Category sales ranks over time, with the best rank since tracking began.
- Reviews — the actual review text — plus rating-average movements, merged into one feed.
- Your Amazon author page: which editions are on it, which are missing, and a way to add the missing ones.
- Audiobooks (Virtual Voice and human-narrated) with narrator, length, and Audible rating.
- Every format and language edition of a title, grouped so the numbers add up.
How TitleVitals Accesses Your Data
It reads the same report pages you can already open in your own signed-in browser.
TitleVitals reads your own Amazon data from your own already-signed-in browser session, through a small Chrome extension. It reads the same report pages you can already open yourself in KDP, Author Central, ACX, and Audible — nothing is read that you could not already see on screen.
Why the extension exists
KDP provides no public API for this data, so the extension collects it from pages you already have permission to view. That is the only practical way to bring your sales, page reads, royalties, ranks, and reviews together — Amazon does not hand this data to outside services, so it has to be read from your own session.
What leaves your browser
The extension parses each report page on your machine and sends only the parsed numbers to your dashboard — sales counts, page reads, royalty amounts, ranks, review text, and the catalog metadata that goes with them. The raw pages stay in your browser; only the figures you can already see for yourself are forwarded to your account.
What it can and cannot change
TitleVitals is read-only where it matters most. It never changes your book listings, prices, categories, series membership, or publishing status, and it never moves money. Your KDP, ACX, and Audible accounts are only ever read — by design, the tool cannot unpublish a book, edit a price, or touch your royalties.
The single exception is editorial content on your Author Central page — your book descriptions, About the Author, and similar fields — which TitleVitals publishes only when you choose to from the app. Every such change is logged and reversible: you can roll a field back to what it said before, so publishing is never a one-way door.
What it shows is a faithful mirror of Amazon, not a second version of the truth. Real numbers are shown as real and estimates are labeled as estimates; nothing is invented. When something changes on Amazon — a price, a series, or a book you remove — your dashboard follows the source rather than keeping a stale copy.
What authors use TitleVitals for
The everyday jobs it does, beyond the obvious sales numbers.
Most KDP dashboards lead with sales and royalties. Those are here too, but a lot of the day-to-day value is in the things Amazon makes hard to watch. Authors reach for TitleVitals to:
- Track launch performance — watch a new release's sales, page reads, and rank in the days after launch without reopening five reports.
- Monitor KU/KENP reads — see Kindle Unlimited page-reads day over day, with an estimated dollar value clearly labeled as an estimate.
- Find books missing from your author page — surface editions and formats that should be on your Amazon author page but are not, and add them.
- Watch rank history — see whether your books are actually climbing or falling instead of checking rank manually every day, with your best rank ever kept on record.
- Manage large catalogs — keep dozens or hundreds of titles, formats, and language editions in one grid instead of scattered across separate ASINs.
Typical workflow
What a normal day with TitleVitals looks like.
Once the extension is set up, most authors settle into a short routine. A typical morning:
- Open TitleVitals — it shows the latest synced data, no report-hopping required.
- See yesterday's sales, page reads, and rank changes on the Home tab, summarized into a few cards.
- Read any new reviews in one feed, across marketplaces and audiobooks, instead of hunting Amazon product pages.
- Check for books missing from your author page, and add any that should be listed.
- Over time, watch launches and promotions — log a promo or price change as an event and see how sales, reads, and rank respond.
Home timezone
Why your dates stay consistent across every device.
TitleVitals stores every time as an exact moment and shows it to you in your "home timezone." This keeps your dates consistent everywhere: a review shows the same date whether you open TitleVitals on your laptop while traveling or on your desktop at home.
Your home timezone is set automatically the first time you sign in, based on your browser. You can change it any time under Settings → Home timezone — handy if you relocate, or if you often work from a timezone other than the one you consider "home."
Getting started
Install the extension, sign in to Amazon, and your catalog fills itself in.
Setup takes a couple of minutes and happens once. The browser extension is the normal way TitleVitals gets your data — it does the heavy lifting in the background, for free, even when the website is closed.
Do these first — recommended order
Follow the steps below in order. Steps 1 through 3 are the core setup. Step 4 (Series Families) is easy to skip but important: do it early, before you rely on any feature that spans multiple series.
- Basic site setup: create your account, install the Chrome extension, paste your API key, and sign in to KDP and Author Central so the first sync can run.
- Settings: open Settings in the dashboard and configure notifications and your root language (the language you publish in first).
- First sync: visit your KDP Bookshelf and reports pages once so the extension captures your catalog. The rest happens automatically in the background.
- Build Series Families (do this early): go to Series Manager and link your translated or companion series into families. This step matters because family-wide features only work after the links are in place — including applying a Fiction or Non-fiction label across an entire cross-language family in one tap, cross-language coverage-gap analysis, and having the right benchmark context for percentile ranks.
1. Create your account
Sign up with your email and a password (at least 8 characters, including a number and a special character). You will confirm your email before the account is active.
2. Install the Chrome extension
- Install the TitleVitals extension in the same Chrome profile you use for KDP.
- Open the extension options. The API base is pre-filled (https://titlevitals.com).
- In your TitleVitals dashboard, open Settings and copy your personal API key.
- Paste that key into the extension options and Save. The key links the extension to your account and is personal to you — never paste a shared or admin key here.
3. Sign in to your Amazon services
In that same Chrome, make sure you are signed in to the Amazon services you use:
- KDP (kdp.amazon.com) — your catalog, sales, KENP, and royalties.
- Author Central (author.amazon.com) — your author page, reviews, and ranks.
- ACX (acx.com) — human-narrated audiobook sales, if you publish audiobooks there.
- Audible (audible.com) — public audiobook pages for ratings (no login needed; these pages are public).
4. First sync
Visit your KDP Bookshelf and reports pages once so the extension can do a first read; your catalog auto-populates. Your author page is detected automatically from Author Central, so in the normal case you do not need to paste any URL. After the first sync, the extension keeps things current in the background and a scheduled job tops it up — you do not have to babysit it.
If the wrong Amazon account got connected
TitleVitals connects your KDP account automatically the first time the extension captures it — there is no button to press. On a shared computer, though, the browser could be signed in to a different author's KDP account when the first capture happens, and that account would get connected by mistake. When that occurs, sync pauses for your security and the dashboard shows an account-mismatch notice.
The fix is simple: sign in to your own KDP account (kdp.amazon.com), and TitleVitals reconnects on its own the next time the extension captures — Amazon only keeps one account signed in at a time. If you need to clear the connection first, open Settings and use the red Disconnect KDP account button; it clears only your own connection, keeps your synced data, and lets the next valid capture reconnect automatically.
The TitleVitals Chrome extension
Your free background worker. It reads Amazon from your own session, then stays out of the way.
The extension runs on your machine, in your already-signed-in Chrome, and reads only the report pages you can already see. It reads your KDP and Amazon session to capture daily sales, KENP page-reads, and royalties, and sends only those parsed numbers back to TitleVitals.
What it reads, and from where
- KDP (kdp.amazon.com, kdpreports.amazon.com): your full catalog (Bookshelf), per-title sales, free downloads, KENP page-reads, royalties, and Virtual Voice audiobooks.
- Author Central (author.amazon.com): your author page (which editions are listed), customer reviews, and category sales ranks.
- ACX (acx.com): human-narrated audiobook sales.
- Audible (audible.com): public product pages for audiobook ratings, narrator, and length.
How it stays out of your way
- It works in the background. You do not sit and watch hundreds of items sync.
- It only acts on Amazon pages you are signed in to; it cannot see anything else you browse.
- If you run TitleVitals on more than one computer, only the newest version actively captures, so an older copy can never write stale data over fresh data.
- KDP reports update on Amazon's schedule, so the extension and a scheduled job keep your data fresh without constant work.
Running on more than one computer (optional)
You do not need more than one computer. A single computer that is on and signed in regularly keeps everything up to date on its own. But if you happen to use TitleVitals on two or more computers, they automatically share the work — an optional way to make syncing faster and more reliable. This mainly helps if you have a large library or already work across several machines.
- Faster: the capture work is split across your signed-in computers, so a big catalog finishes sooner than one machine doing all of it.
- More reliable: if one computer is asleep, offline, or has a flaky connection, another picks up its share automatically — your data keeps flowing instead of stalling until that machine is back.
- Safe: only computers running the newest version capture, so an older copy can never write stale numbers over fresh ones, and the same item is never captured twice.
- Nothing to set up: install the extension on each computer and sign in to the same TitleVitals account. The sharing and hand-off happen on their own — there is nothing to configure or coordinate.
Which browsers are supported
Keep two things separate. The TitleVitals website — and the installed app — works in any modern browser (Chrome, Safari, Firefox, Edge) on your phone or your computer. That is just a read-only view of your synced numbers.
The data-capturing extension is a different matter. It is a Chrome (Manifest V3) extension, so it runs only in Chromium-based browsers. Those include:
- Google Chrome
- Microsoft Edge
- Brave
- Opera
- Vivaldi
- Arc
Add TitleVitals to your phone or desktop
TitleVitals installs as an app from your browser — add it to your home screen or dock for a full-screen, app-like experience with pull-to-refresh, and no browser address bar.
On iPhone or iPad (Safari)
- Open titlevitals.com in Safari.
- Tap the Share button (the square with an up arrow).
- Scroll down and tap "Add to Home Screen".
- Tap Add — a TitleVitals icon appears and opens full-screen.
On Android (Chrome)
- Open titlevitals.com in Chrome.
- Tap the three-dot menu (top right).
- Tap "Install app" (or "Add to Home screen").
- Confirm — the icon is added to your home screen / app drawer.
On desktop (Chrome or Edge)
- Open titlevitals.com.
- Click the install icon in the address bar (a small monitor / computer icon), or use the browser menu → "Install TitleVitals".
- It opens in its own window.
The Home tab
Your at-a-glance summary: sales totals, newest sales, top ranks and top-rated books.
Home is the landing view. It is built from the same authoritative data as the other tabs, summarized into a few cards.
- Sales totals box — a clickable card showing today and this-month totals: book sales (paid units), free downloads, KENP pages, and, on a plan with the dollar layer, total royalty. Tapping it opens the Sales tab.
- New sales feed — the most recent individual sales with cover, title, format chip, and a paid/free label. You can filter to All, Paid, or Free.
- Top ranks — your best-ranking titles, each with its current rank, category, and a 24-hour trend arrow. Tapping a row drills into Ranks.
- Top-rated books — your highest-rated titles by a confidence-weighted average, with stars and rating count.
- Author-page reminder — if editions are missing from your author page, a note links you to Books to add them.
The Sales tab
Per-title sales, KENP and royalties — steerable by period, format, language and country.
Sales is a single, steerable list of your books with the metrics that matter, plus a totals table for whatever you have filtered to.
Controls
- Period: Today, Yesterday, 30 days, Month, Year, or All time. "30 days" is a rolling window (the last 30 calendar days including today, matching KDP's own Last-30-days view) — unlike Month, it never resets to zero on the 1st. ("All time" means everything captured since tracking began — KDP only exposes recent per-title data, so sales from before you started tracking are not included.)
- Units: All, Paid, or Free.
- Marketplace codes: the two-letter badges are Amazon storefronts — US Amazon.com, UK Amazon.co.uk, DE Germany, FR France, ES Spain, IT Italy, JP Japan, CA Canada, AU Australia, BR Brazil, MX Mexico, NL Netherlands, IN India, SE Sweden, PL Poland, TR Türkiye, AE UAE, SG Singapore. International sales are booked on the marketplace's own local day, which can run a day ahead of the US reporting day.
- Language and Country (marketplace). Per-country sales are only available for the current month; the daily trend and all-time totals are reported across all marketplaces together.
- Fiction / Non-fiction, and a Kindle Translate toggle if you have AI-translated editions.
- Sort: Most recent, Most units, Most KENP, or Highest $ (the last only on a plan with the dollar layer).
The totals table
The table at the top totals the filtered list below it. Rows include Total royalty, Paid sales (units), KENP pages, and Free downloads. Counts are shown to everyone; the dollar columns (royalty, KENP dollar-estimate, currency totals) appear on plans that include financials.
The per-title list
Each row is one edition (a title in one format): cover, title, format chip, paid units, free units, KENP pages, royalty (on a financials plan), and the last sale date. You can export the list as CSV at any time.
Series Manager
Link your same-story series across languages into one family — our own grouping, never touching Amazon.
Kindle Translate (AI) editions inherit their series from the PARENT book they were translated from, so Amazon automatically groups them into that same series, flowing across languages. But a series you published yourself under a translated name (your own German, Spanish, French edition and so on) usually becomes its OWN author-created series, one per language, on Amazon. Kindle Translate editions cannot be assigned to those translated series (at least for now), so those per-language series show up SEPARATELY here. The Series Manager lets you tie the related series together yourself, so Series Analysis can compare one story across all its languages.
How to use it
- Set your root language — your primary publishing language (English is pre-suggested, but it is your choice). Each series you publish in that language becomes the root of a family.
- Confirm the suggested links: when two series names share a name (like "Roger and Isabel" and "Roger y Isabel"), the Manager suggests linking them. You confirm each one — it never links automatically.
- Link the rest by hand with the "Link to…" picker, or leave a series standalone. A series published only in another language can stand on its own as a root.
- Unlink any time — the grouping is entirely ours and changes nothing on Amazon.
Series Analysis
Compare per-book sales, KENP and royalties across each of your series, in series order.
At the bottom of the Sales tab, Series Analysis groups your books by their KDP series membership and shows each book's sales, KENP page-reads and dollars with the books laid out in series order. Standalone titles are not included. The section appears once you have at least one series; if you have none, it stays hidden.
How to use it
- Pick one series or several with the checkboxes (or All) to choose what you compare.
- Choose the period — Today, This month, This year, or Lifetime. This selector is independent: it ignores the Sales tab's other filters (marketplace, language, format and so on) so a series always shows its full figures.
- Type in the search box to filter by title — handy with large catalogs; a series with no matching book drops out of view.
- Read the per-book figures down a series (paid, free, KENP page-reads and dollars) to see how sales hold up book to book.
- With more than one series selected, switch between Grouped (each series shown in its own block) and Merged (all selected series combined into one ordered list).
- Sort series by: orders the series themselves — by Sales, KENP, Units, Language or Name. (It appears only in Grouped view with more than one series; Merged is a single list, so it is hidden then.)
- Sort books by: orders the books within each series — by series number (Book #), name, income, units or KENP.
Save series report (PDF) opens a print dialog (choose Save as PDF) and Download series CSV exports the rows — one line per book plus a per-series total — so you can share or analyze them elsewhere.
The Books tab and book detail
Your catalog as a grid — one card per title and language — with a full detail page for each.
Books is your catalog. It shows one card per title-and-language, with format chips for the editions that exist in that language. Translated editions are separate cards (that is how Amazon models them), each with its own cover and title.
Finding things
- Search by title.
- Filter by format (Kindle, Paperback, Hardcover, Audio), by genre (Fiction / Non-fiction), and by language.
- Filter by author-page status: All, Yes (confirmed on your author page), No (missing), or Pending (submitted, awaiting confirmation).
- Show inactive to include editions that are hidden by default.
The book detail page
Tapping a card opens the detail page for that title:
- A hero area with the cover, title, rating, and at-a-glance format chips. If the title exists in more than one language, you can switch the active language.
- A Type selector (Fiction / Non-fiction) that you set once per title; it applies to every edition of that title and is never auto-overwritten.
- Editions, grouped by language and format, each with its publish date, ASIN (click to copy), rating, and author-page status dot. Store links go to Amazon for that edition.
- Sales for this book — units, KENP pages and royalty by period — plus a 30-day mini chart.
- Category ranks for this book, current and best-since-tracking.
- Reviews collected for this title.
- An audiobook section when an audio edition exists (see Audiobooks).
- An events timeline where you can log promos, revisions, price changes, and ad campaigns as markers to correlate with spikes.
- A Promote / share composer (see Sharing your wins).
The Ranks tab
See whether your books are actually climbing or falling instead of checking rank manually every day.
Ranks lists every book with a captured category rank, best current rank first. Each row shows the book, the category (the overall store rank is labeled as such), the current rank with the best rank ever in parentheses, a 24-hour trend arrow, and a sparkline of recent history.
- Search by title or category, and sort by Best rank, Biggest mover, or A–Z.
- Books on a free promotion are marked, and free-promo ranks are tracked separately from paid ranks (free and paid sit on different "ladders" on Amazon).
- Export the table as CSV.
When a category has enough data, a book's rank also appears as a percentile, for example "top ~8%", meaning it ranks ahead of about 92 percent of the books in that category. The "~" marks it as an estimate: it is measured against a sample of the category's size that TitleVitals grows as more books are tracked, so it starts conservative and sharpens over time. Percentiles are shown only when the category sample is large enough to make the estimate useful.
The Reviews tab
Read every new review in one feed instead of hunting across marketplaces.
Reviews is a dated feed of your customer reviews with the real review text, so you do not have to hunt through Amazon. It also surfaces rating activity — how your average moved and how many ratings came in — even when a rating has no written review.
Where reviews come from
- Print and Kindle reviews come through Amazon Author Central, gathered across the Amazon marketplaces where your books are sold, into one feed.
- Audiobook reviews come from Audible and ACX and are captured for your audio editions. They are kept distinct, and audiobook stars are not blended into your print/Kindle average, because Amazon and Audible keep separate rating pools.
How often they sync, and what is kept
- Reviews refresh on the same background cadence as the rest of your data: the extension reads them while you have Author Central open, and a scheduled job tops them up between visits.
- Review history is retained. Once TitleVitals has captured a review, it stays in your feed even if it later disappears from Amazon — so a review someone removes (or that Amazon takes down) is not lost from your own record.
Ratings vs reviews — where each comes from
- A REVIEW is a written post by a named reader: it has a reviewer name, a title, the review text, and that reader’s own whole-star value. We capture it from the review pages themselves.
- A star RATING is anonymous. Amazon never publishes who rated or what value they gave — only each book’s pooled AVERAGE (rounded to one decimal) and its rating COUNT. TitleVitals detects rating activity by comparing captures: the count went up, and the average moved (or held).
- When a rating row shows a specific star value ("new rating: ★5"), it is because the arithmetic allows exactly ONE possible whole-star value behind the average move. When several values are possible — typical once a book has many ratings — no value is shown. We never guess.
- Amazon pools ratings across a work’s editions (Kindle, paperback, hardcover), so one new rating appears once per work, not once per edition. Audible keeps its own separate listener pool.
Working the feed
- The All / Reviews / Ratings toggle switches between the merged date feed, written reviews only, and anonymous rating activity only.
- Filter by book, by star level (including "stars pending" for reviews Amazon has not finished publishing), and sort newest/oldest or by rating. These apply to written reviews; anonymous ratings have no reviewer or text to filter.
- Search across book title, review title, review body, and reviewer name.
- Each review card shows the cover with the review date under it, stars, book, reviewer name, and the body. Open it on Amazon or translate it. Consecutive rating events stack together as one card.
- Export reviews as CSV.
Audiobooks
See your audiobooks — and their Audible ratings — next to your ebooks and print.
Audiobooks appear alongside your other editions, with narrator, length, and the Audible rating. The audiobook list is built only from titles you actually own — Virtual Voice editions from KDP and completed human-narrated titles from ACX. TitleVitals never discovers audiobooks by searching Audible by author name, so another author's work can never slip into your library.
Where each number comes from
- List + ratings + narrator + length: your own Audible product pages (public, no login).
- Virtual Voice sales: KDP, alongside your ebook sales.
- Human-narrated sales: ACX.
The "≈$" income estimate
Next to your ACX audiobook sales you may see a figure marked with a “≈”, for example “Sales: ≈$42”. This is a real-time estimate of your ACX audiobook income for the period shown, refreshed continuously as new sales come in - not the official, lagged statement total.
Amazon's own ACX royalty statements are not real-time: they typically arrive about two months after the fact. Without an estimate, you would have no visibility at all into the last month or two of your audiobook income. The “≈$” figure exists to close that gap.
Once Amazon's monthly statement for a given period arrives, TitleVitals captures that period's confirmed dollar figure and shows it alongside the estimate, labeled “confirmed by statement.” Older, statemented months are always exact - only the most recent month or two, the ones Amazon has not reported on yet, are estimates.
Languages and editions
See series-wide performance instead of numbers scattered across separate ASINs.
A title can exist in several formats (Kindle, Paperback, Hardcover, Audio) and several languages. TitleVitals groups all the formats of one title-and-language into a single card, and shows each translated edition as its own card with its own cover and title — the way Amazon actually models them.
- On a title's detail page, you can switch the active language; the description, rating, and buy/format links follow that language.
- AI-translated editions (Kindle Translate) are detected and labeled, and the Sales tab has a Kindle Translate toggle. If a translated edition looks like a duplicate of one you already have, it is flagged so you can cancel it in KDP.
- Edition language is filled in automatically as data syncs, so you rarely need to set anything by hand.
Invite an author, get a free month
Share your invite link; when someone you invited goes Pro, your next month is on us.
How to use it
- Copy your personal invite link from the Home card (or Settings → Referrals) and share it anywhere — email, a group, social.
- Anyone who signs up through your link is counted as your referral. The card tracks invited → opened → went Pro.
- When a referral converts to a PAID Pro plan, you earn one free month of Pro.
The rules (plain-English summary)
- You earn when your referral actually PAYS for Pro — a signup or trial alone does not trigger the credit.
- Credits apply to a PAID subscription: they redeem against your next renewal (they cannot be cashed out).
- One credit per referred author, no limit on how many authors you refer.
- The person you invite gets the normal intro preview; your credit never shortens or changes their plan.
- The full, binding terms live at titlevitals.com/terms.html#referrals — this page is the friendly summary.
Contributed titles (co-authored books)
Books you are credited on but did not publish yourself — public data only, never in your sales.
A contributed title is a book that appears on your Amazon author page because you co-authored it, but which you did NOT publish through your own KDP or ACX account — a co-author published it. Most authors never have one; it is a rare special case.
What you can and cannot see
- You CAN see: reviews, ratings, sales rank, and the book's public details (title, cover, description, series).
- You CANNOT see: units sold, KENP pages read, or royalties — that data lives inside the co-author's publishing account and is not available to you. We never show a $0 for these, because the figure is not zero, it is simply not available to you.
Where it appears
- On the Books page, in a separate "Contributed titles" section, clearly badged.
- As a target for promotion cards and share links (it is a real book you can promote).
- In reviews, ratings and rank views.
- NEVER in the Sales page or any sales, units, KENP or royalty total — it is kept entirely out of those figures so nothing is ever miscounted.
When you have at least one contributed title, a "Contributed only" filter appears on the Books and Reviews tabs (off by default) so you can focus on just these titles. It does not show up at all if you have none.
Notifications and the email digest
A nudge when something worth celebrating happens — in-app, push, or one summary email.
The matrix
Settings → Notifications is a grid: events down the side (Sales, New reviews, Rank gains, Milestones, KENP page reads), delivery methods across the top (In-app = the tab dots and app-icon badge; Push = a device notification). Tick exactly what you want; the presets (Everything / Wins only / Sales only / Off) are one-tap fills of the same grid.
Push on your phone
Push requires the installed app: tap Share → "Add to Home Screen," open TitleVitals from your home screen, then press "Enable push on this device." Each device is enabled separately.
The email digest
- One summary email at the cadence you pick — daily, weekly, or monthly (or off, the default). It covers paid sales, free downloads, KENP pages read, new reviews, and your best rank for the period.
- Daily digests are skipped on days with nothing to report — no empty mail.
- Dollar figures appear only in the daily digest (yesterday's exact reported royalty) and only on plans that include financials.
- There are no other per-event emails: the digest is the only mail about your numbers.
Plans and what each one gets
Everyone sees the whole catalog and the sales counts. The paid layer is the financials.
TitleVitals has four plans — Intro (the automatic 14-day preview every new account starts on), Author (free forever), Pro, and Pro AI. The guiding rule: everyone sees their entire catalog, all ranks and reviews, and their sales counts — the limits are on the dollar layer, a few actions, and the AI features.
- Intro — a 14-day preview of Pro AI at the free price. New accounts start here. You get the full experience, including the financials and a trial-sized AI allowance, so you can see the full value before deciding.
- Author (free) — after the intro ends. You keep seeing your whole catalog, ranks, reviews, and sales counts, but the dollar layer and paid actions turn off.
- Pro — financials, email alerts, unlimited author-page publishing, and bulk editorial pushes.
- Pro AI — everything in Pro, plus the AI layer: review insights, category opportunities, author reports and series analysis, AI editorial drafting, and built-in AI translation.

Privacy and security
No tracking pixels — only your own parsed numbers.
About Chrome's install warning: Chrome shows the same “read and change your data” wording for every extension that can see a web page — it does not distinguish reading from changing. TitleVitals reads your KDP reports, Author Central, ACX, Audible, and Amazon book pages to collect your numbers; the ONLY place it ever changes anything is your own author page (adding books or publishing editorial fields), and only when you request it from the app. It can never change your prices, categories, or publishing status, and never moves money — those live in KDP and are only ever read. It never reads websites outside that list, and never sees your Amazon password.
Data we send to TitleVitals
Only parsed numbers and catalog metadata — never raw pages. Specifically:
- Sales units, KENP pages read, and royalty amounts.
- Sales rank, and review text with star ratings.
- Book titles, subtitles, formats, ASINs, languages, and list prices.
- Author-page coverage (which editions are listed).
- Audiobook narrator, length, and ratings.
Data we never send
- Payment card details — Stripe handles billing on its own secure domain.
- Your browsing history, or anything from non-Amazon sites.
Is it stored?
Yes. Your parsed numbers live in TitleVitals' database, scoped to your account, so your history and trends persist between visits. We store your account (email, plan/billing status), your catalog data, and your settings (genre classifications, logged events, share links). Every read and write is scoped to your own account and your own ASINs.
Can you delete it?
Yes. You can delete your account or request deletion, which removes your account and your personal links to the data.
Extension permissions, and why
- Host access to author.amazon.com, kdp.amazon.com, kdpreports.amazon.com, www.amazon.com, acx.com, and audible.com — to READ your own reports.
- Host access to titlevitals.com — to send the parsed numbers to your dashboard.
- Storage — to hold your API key and a record of what has already synced.
- Alarms — to run background syncs without keeping a tab open.
- Notifications — to show sync status.
Why the extension needs an API key
The API key tells the extension which TitleVitals account to send your numbers to, so they land in YOUR account. It is not your Amazon login, and it is never shared with anyone.
Inspectable by design
The extension is a published Chrome extension, and the data it posts is plain JSON of the parsed numbers — nothing hidden. We do not sell your data or share it with third parties beyond what is needed to run the service (such as Stripe for billing and email delivery for the messages you opt into).
Troubleshooting
The common hiccups and what they mean.
Covers or details are slow to appear
After a first sync, covers, ranks, and some metadata fill in gradually as the background sweep works through your catalog. A large catalog takes longer. Leave Chrome running and they will continue to fill in; nothing is missing, it is just still loading.
Data is not updating
- Make sure the extension is installed in the Chrome profile where you are signed in to KDP, and that your API key is pasted into the extension options.
- Open your KDP and Author Central pages once to give the extension a fresh read.
- KDP figures for "today" can lag during the day; the month totals are the complete picture and a scheduled job tops things up.
- If you use more than one computer, only the newest extension version captures — update the extension everywhere so an older copy is not sitting idle.
A sync says it was rate-limited
Amazon sometimes throttles repeated report requests. TitleVitals retries automatically, and the scheduled sync (which runs on a regular cadence) will keep trying. You do not need to do anything; your saved data stays put in the meantime.
It says Amazon served a "limited page"
Amazon sometimes serves our server a trimmed version of a page. When that happens, your full catalog still stays current through the extension running in your own browser. This message is informational — it is telling you which path the data came from, not that anything is lost.
A title is missing, or one I removed reappears
- TitleVitals keeps your known titles even when a single data source has a bad day, so titles do not vanish because one pipe broke.
- For the author page specifically, remember that publishing only adds; there is no self-serve removal. To remove a title from your author page, contact Amazon support or unpublish it on KDP.
A password reset email did not arrive
Check spam/junk — a new sending domain can land there at first. If it still does not arrive, try the reset link in a regular browser tab rather than the installed app, in case a cached version is being served.

AI editorial publishing to Amazon (Pro AI)
Let AI write the first draft of your editorial fields — you always review, edit, and decide what publishes.
Amazon gives authors several extra product-page fields beyond the description — From the Author, Inside Flap, Back Cover — but makes you manage them one field, format, and edition at a time. One book across Kindle, paperback, and hardcover is a dozen entries; translations or a series multiply it fast. TitleVitals turns that into a bulk workflow: pick the editions or series, write the content once in your root language, and TitleVitals can AI-edit it for Amazon compliance, translate it, publish it to the matching fields, and track which submissions later appear live. You always review before anything publishes.
Publishing rides Amazon's own editorial review, which can take from hours to several days — so nothing you push appears instantly, and the same is true of corrections. The workflow: Select editions → Draft → AI review → Translate → Publish → Track (submitted, awaiting Amazon, live, failed) → Rollback. Changed your mind while a push is still awaiting Amazon? Just publish the fix or hit Restore — the newer submission supersedes the old one, and the field settles on your latest text. After something is live, Restore rolls the field back to the previous version (or to the original Amazon copy from before your first push, which TitleVitals snapshots automatically). A rollback is itself a submission, so the wrong text stays visible until Amazon processes it — there is no faster undo; Amazon has no cancel button. Review time varies — early pushes have landed in under 24 hours, but expect longer as Amazon's volume grows. Two practical notes: your edition selection locks once you start editing — to change which editions you're working on, close the editorial window and reselect from the filters. And if a field was blank before your first push, restoring 'blank' is unreliable — Amazon may reject an empty submission, and clearing a live field can take an Amazon support request; replacing the content with better material usually beats trying to blank it.
What TitleVitals changes — and what it never touches: it does not edit your KDP books, pricing, files, rights, or billing. It reads KDP data for your catalog and reports, and the only Amazon-side changes it makes are the actions you specifically request: adding selected books to your author page, and publishing selected editorial fields. Every publish is logged, tracked, and reversible from inside the app — and TitleVitals warns you before likely mistakes, such as book-specific text about to fan out across multiple titles.
- Every editorial field (Description, About the Author, From the Author, Inside Flap, Back Cover) has a ✨ AI edit button that reworks and improves the field in the language you are editing — it edits from your material rather than inventing from nothing, so it works best when there is already something to improve (your rough text, captured content, or a saved bio profile).
- Drafts are grounded ONLY in your own captured material — your book’s metadata, existing editorial content, and saved bio profiles. The AI never invents facts, reviews, awards, or plot details.
- Amazon’s content rules are built into the generator: no links or contact info, no price or availability language, no review solicitation, no time-sensitive claims — so a draft won’t get your push rejected in Amazon’s review.
- Nothing publishes by itself. The draft lands in the edit box exactly like typed text; you review, edit, translate, and publish it with the same per-field buttons.
- AI features are used at your own risk: output quality depends on the quality and amount of material you provide, and each edit or translation counts against your monthly allowance when it runs — whether or not you keep the result. Always review before publishing; you are responsible for the final text.
- AI edit needs real material to work from — a rough draft, a few concrete facts, captured content, or a saved bio profile. If you want finished copy generated from scratch (for example an Inside Flap when you have written nothing yet), draft it with your own AI tool of choice and paste it in; AI edit will then shape, tighten, and keep it Amazon-compliant.
- Running low? When either meter drops to 10%, a Buy AI recharge button appears in the balance bar: $5.99 adds 250,000 translation characters + 100 AI edits. Recharge credits are spent only after your monthly allowance runs out, oldest purchase first, and expire 90 days after purchase.
- Review insights (book detail page): free stats compare your written-review average against silent ratings, plus an AI analysis of what readers praise and criticize with constructive takeaways — cached until new reviews arrive (regenerating costs 1 AI edit). Print / Save PDF from the panel.
- Category opportunities (book detail + report): smaller sibling categories where the same sales go further — computed from observed category sizes, clearly labeled as places to evaluate, never rank predictions.
- Monthly Author Report: units, KENP, royalties, medal standings, new reviews, and category opportunities for the prior month, with a short AI summary — reports exist for last week, last month, and the last 12 months (completed periods only — data and AI summary are computed once per period and cached). Find them on the Home page's Reports card (unopened ones are marked NEW, and a blue “New report available” line appears up top until you open it); the monthly one is also emailed on the 1st. Use Share or Print / Save PDF on the report page.
