Inkario — Self-Publishing Research

Book niche research for self-publishers: opportunity scores, trademark screening, BSR backfill, and one-click sync to Inkario.

Inkario turns any Amazon book or search page into a research surface for Kindle Direct Publishing (KDP) authors, and keeps your own publishing numbers current without a spreadsheet. RESEARCH, ON THE PAGE YOU ARE ALREADY LOOKING AT - Opportunity score on any book page, with the real Best Sellers Rank — measured, not estimated. - Niche analysis: score a whole search-results page and backfill each competitor's true BSR. - Trademark and copyright guard: flags high-risk brands and characters, or confirms public-domain source material, before you commit to a title or keyword. - Live HUD: see what your Inkario account already knows about a book or niche — owned, analyzed, tracked or saved. - Track author: follow a competitor from any of their book pages, with real BSR and price feeding your watchlist. - Review capture: visible customer reviews are captured with a book, powering review intelligence in the app. Reviewer names are reduced to initials in your browser before anything is sent. YOUR OWN KDP DATA, KEPT FRESH - Sales and royalties from your own KDP sales report. - Bookshelf, listing fields, rank, reviews and A+ content status. - Keyword rank tracking for the keywords you pin. - One freshness panel in the toolbar: what is current, what is due, and a button per row to refresh just that. YOU DECIDE WHAT RUNS Nothing reads a page until you accept the consent card shown on first use. Daily background sync is OFF until you switch it on, and when it is on it opens one unfocused tab at a time to a page it already has permission for, then closes it. No Amazon password or cookie is ever read. Connect once from the toolbar popup. An Inkario account is required for syncing; a free tier is included.
