Readers asking. Few books answering.
For every trope in your lane we count reader requests and the books already carrying it. High asks, few books: that's the square to play.

Every other tool reads Amazon. We read the readers.
Amazon only shows you what already sold. By the time a gap shows up there, someone else has filled it. We count what readers are asking for right now, against what's on the shelf, trope by trope.

Built on over 35.4 billion BookTok plays.
No competitor reads what readers actually engage with.
Most "trope intelligence" tools recycle 2022 bestseller lists. Tropesmith ingests live BookTok virality, Goodreads reader shelves, Amazon supply, and Reddit asks — weighted by what readers are reaching for this month.
Our recommendation engine weights BookTok signals highest — a viral video carrying millions of plays is the strongest social-proof signal in the corpus. Reddit asks come second (explicit reader requests). Goodreads reviews come third (single-reader praise). Then we cross-reference what's over-supplied on Amazon to find the gap. That's what your Map reflects.
Live corpus totals — updated continuously as we ingest more reader signals.
What Tropesmith has actually read
Every figure on this page is a row count against our own corpus, not an estimate. The counters above animate for visitors but ship their final values in the page source, so a search engine or an AI assistant reads exactly the same numbers you do. Here is the whole set in one place.
Counted 2026-09-25 09:42 UTC by direct query against the Tropesmith corpus. Method: how we read reader demand · how a Map is built · the published cut of this corpus: PlotProse’s 2026 Romance Demand Report.
