The short answer: K-lytics sells reports — analyst-written genre studies covering category size, competition, pricing and review norms, delivered as documents you read once. The strength is synthesis: someone has done the reading and drawn conclusions. The structural weakness is the same thing that makes it a report — it is fixed at the moment of writing, and a genre moves. If you want the same genre-level picture but live and at trope resolution rather than category resolution, that is what Tropesmith produces.
A good genre report is a real shortcut. It gives you the shape of a category — how many books compete, what they charge, how many reviews the top of the list carries, which subcategories are growing — with the analysis already done, and that is worth paying for if you are moving into a genre you do not know. See the vendor for current report pricing and coverage; we do not track it.
Two limits, and both are inherent rather than criticisms of the work. First, a report is a photograph: it is accurate on its publication date and drifts from then on, and a romance subgenre can turn over inside a season. Second, it operates at category resolution — how the Regency Romance category behaves — when the decision you are actually making is at trope resolution: which premise inside that category readers keep asking for and not getting.
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 want written genre analysis, there is no exact substitute - it is a research product, not a software feature, and Publisher Rocket, KDSpy and BookBeam all give you raw numbers rather than conclusions. If what you want is the underlying picture live and at trope level, Tropesmith publishes lane-level demand on this site, dated, free to read.
If you are entering an unfamiliar genre and want the landscape summarised by someone who has done the reading, a current report is a genuine shortcut. Check how recently the report for your genre was updated before buying - the value decays with age, more quickly in fast-moving romance subgenres than in stable ones. Pricing is on the vendor's site; we do not track it.
Resolution and freshness. A report tells you how a category behaves as of its publication date. Tropesmith tells you which tropes inside a lane readers are requesting right now and what share of those requests the shelf has not answered, from 721,971 classified reader requests across 138 demand lanes - each number stamped with the date it was counted.
Some of it. The market snapshots and trope demand pages on this site are open with no signup, and Amazon's own bestseller lists give you a rough read on competition if you are willing to do the counting yourself.
Yes. The demand engine scores 138 lanes spanning romance, fantasy, mystery, thriller, horror, historical fiction and science fiction. Romance is the deepest coverage because that is where the reader conversation is densest, but the trope pages and lane snapshots are not romance-only.
