The short version: K-lytics genre reports are analyst-written studies of a book category — how crowded it is, what the top of it charges, how many reviews the leaders carry, which subcategories are growing. They are a real shortcut into an unfamiliar genre. The one thing to check before you buy is the date on the report for your genre, because the value decays from publication day and it decays faster in fast-moving romance subgenres than in stable ones. We build the competing kind of data, so read this knowing that — and note that the honest verdict below is that a report and live demand data answer different questions.
Synthesis. Raw category numbers are easy to gather and hard to interpret, and a written report hands you the interpretation: this subcategory is saturated, that one is thin, this price band is where the reads are. If you are moving into a genre you do not read yourself, that is worth paying for, and it is faster than assembling the same picture by hand.
A report is fixed at its publication date. Category composition, pricing norms and which subgenres are rising all move — sometimes inside a single season, as anyone who watched romantasy reshape the romance charts can attest. Before buying, check when the report covering your genre was last refreshed, and treat anything more than a few months old as direction rather than fact.
Reports work at category level: how Regency Romance behaves. The decision an author is usually making sits one level down, at trope level: which premise inside that category readers keep asking for and not getting. That is not a flaw in the reports, it is a different unit of analysis — and it is the unit Tropesmith works in.
Here is the distinction that matters, and it is not a slight on anyone's tool. Keyword and category research answers how do I get this book found. It assumes the book exists. Tropesmith answers a question that comes earlier and that no keyword tool attempts: which story do readers keep asking for and not getting. We count individual reader requests — a real person, in a review or a comment or a BookTok video, describing a book they want and cannot find — classify each one by trope, and score it against what the shelf actually supplies in that lane. Tropesmith reads a registry of 231,291 books, 2,679,139 Goodreads reviews, 67,499 book–trope tags across 11,575 fully tagged titles, and 721,971 classified reader requests, scored across 138 demand lanes — plus an hourly scan of 554 BookTok hashtags (72,641 videos logged, 27,618 reader requests read from BookTok).
What Tropesmith is not. It is not a keyword tool: it will not give you Amazon search volumes or seven backend keyword strings. It does not estimate anyone's sales or revenue. It does not build or bid your ads. If those are the jobs in front of you, the tool on this page does them and Tropesmith does not replace it. Plenty of authors run both, and that is the honest recommendation.

Tropesmith figures counted 2026-08-21. Rival capabilities are described from their published feature sets; we do not track anyone's pricing and deliberately quote none — check the vendor, and see our pricing page for ours.
The corpus behind every Tropesmith number on this page, counted on 21 August 2026.
Counted 2026-08-21 18:49 UTC by direct query against the Tropesmith corpus. Method: how we read reader demand · how a Map is built.
A Tropesmith Map scores your exact trope stack on live demand versus supply — and names the gap you can own.
Build my Map → See a real sample Map first → See pricing →If you are entering a genre you do not know and want the landscape summarised, a recently updated report is a genuine shortcut. Check the refresh date for your specific genre first - that is the single variable that decides whether it is worth it. Pricing is on the vendor's site and we do not track it.
Broadly: how large and competitive a book category is, what the books in it charge, how many reviews the leaders carry, and which subcategories are growing or shrinking, with an analyst's reading of what that means. Coverage varies by genre - check the sample or table of contents for the specific report before buying.
As current as the report's publication date, which is the structural limit of any report. Genres move; romance subgenres move fastest. Always look at when the report for your genre was last refreshed rather than when the catalogue page was last touched.
Live data you query yourself. Tropesmith scores 138 demand lanes from 721,971 classified reader requests, and publishes the lane snapshots and trope demand pages free on this site with the count date on every figure. It gives you no written analysis - that is the trade.
No, and pretending otherwise would be worse. We build a competing kind of data and we would rather you knew that while reading. What we have tried to do is be accurate about what the reports genuinely do well - synthesis and speed into an unfamiliar genre - and specific about the one real limitation, which is that a fixed-date report drifts.
