Know which tropes readers name and praise.
We count the demand signals in Goodreads and Amazon reviews, BookTok comments and Reddit posts (the tropes readers name and praise), and what's already selling on Amazon, trope by trope. Then we lay your opening out on the desk: a score, three priorities, and the proof.

Readers talking. Books counted.
For every trope in your lane we count demand signals and the books already carrying it. Many signals, few books: that's the square to check.

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 demand signals from reviews, comments and posts, against what's on the shelf, trope by trope.

Built on 2,860,000+ demand signals.
No competitor reads what readers actually engage with.
Most "trope intelligence" tools recycle 2022 bestseller lists. Tropesmith ingests BookTok comments and captions, Goodreads and Amazon reviews, Goodreads reader shelves, Amazon supply, and Reddit posts.
Demand signals come from Goodreads reviews, Amazon reviews, BookTok comments and captions, Reddit posts and Amazon Q&A. 95.6% come from Goodreads and Amazon reviews, 4.1% from BookTok comments and captions and 0.3% from Reddit posts (source shares counted 7 October 2026). Then we cross-reference what's over-supplied on Amazon to find the gap. That's what your Map reflects.
The demand signals figure was counted 2026-11-05 10:15 UTC. A demand signal is one specific thing a reader asked for or praised in a review, comment or post, picked out by Tropesmith's classifier. One review can give several. How we count
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 by direct query against the Tropesmith corpus. Each of the 2,860,000+ and 113,500+ floors was counted 2026-11-05 10:15 UTC; the 39% share is as of 2026-10-07 17:24 UTC. Each other floor above was counted 2026-11-05 10:15 UTC. A demand signal is one specific thing a reader asked for or praised in a review, comment or post, picked out by Tropesmith's classifier. One review can give several. Each signal gets a rarity tag (common, underserved or novel) from the text of that review or post alone; the classifier is never shown what is on the shelf. A tag points at where to look. It does not prove that no book answers the signal. Shares are the tagged signals divided by all signals in the same scope.
