The method

Three signals.
One verdict.

A Map is built from three independent data layers. Each answers a different question, and we never let one overrule the others.

01 · Supply

What's already winning

Every Amazon bestseller in your subgenre. Their tropes, blurbs, cover language, review counts. The whole competitive landscape, read in full and structured for you.

02 · Demand

What readers ask for

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.

03 · Vocabulary

The words readers use

The Goodreads shelves real readers create. Your blurb keywords, ad targeting, metadata. Words that find your readers, not words your editor invented.

What's in a Map

Nine pieces of evidence, two minutes to read.

What we read so you don't have to

Built on 2.18 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.

The mechanism

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.
