Tropesmith reads 2,531 Amazon bestsellers, 9,258 Goodreads shelves, 4,090 BookTok videos and 2,379 Reddit threads so you don't have to. Then we tell you the 5 tropes, 3 comp titles, and market gaps your next book should hit.
A market verdict, not a writing prompt.
A Map is built from three independent data layers. Each answers a different question, and we never let one overrule the others.
Every Amazon bestseller in your subgenre. Their tropes, blurbs, cover language, review counts. The whole competitive landscape, read in full and structured for you.
Reddit threads, Goodreads reviews, BookTok captions. The "I want a book that…" voice in the reader's own words. We mine it, score it, surface the gaps.
The Goodreads shelves real readers create. Your blurb keywords, ad targeting, metadata. Words that find your readers, not words your editor invented.
Every Map ships with the same skeleton. The market verdict changes; the structure doesn't. Read it like an editor would read a manuscript report.
Subgenre, heat level, format, plus any comp titles you've been thinking about. ~60 seconds.
Supply, demand, and vocabulary signals retrieved in parallel against this week's data.
An editorial pass writes the Map: ranked tropes, comps, archetypes, gaps, risks, actions.
The Map flagged a trope I'd planned the whole book around as oversupplied — and pointed me at one I'd never considered. Two months later it's my best-selling release.— Author quote placeholder · swap before launch

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.
