1 credit = 1 Map.
Buy as many as you like — the more you buy, the lower the price per Map, applied automatically. Credits never expire, and you can mix subgenres across Maps.
New here? See two free sample Maps before you buy one.
Try your lane free first — the Lite Map
See your subgenre's live opportunity score, greenlight band, market economics and length sweet spot before you spend a cent. Then decide if the full $15 Map — the ranked trope stack, comps, cover direction and a step-by-step plan for your specific book — is worth it.
Live engine data, no email required. This is the free preview — the paid Map goes deeper for your exact book.
Buy credits — the volume plan
Choose how many Maps you want. Bigger quantities drop the per-credit price automatically — no packs to pick, no plan to lock into. Write 3, 6 or 12 books a year and Tropesmith gets cheaper per book the more you write. Compare that to a one-time desktop tool: pay once, and the read is frozen the day you bought it. Every Tropesmith credit is built from the data on the day you order it.
Every credit unlocks one full Map — a complete pre-launch blueprint: a go/no-go opportunity score, the ranked trope stack with demand-vs-supply, FMC + MMC archetypes, the open gap, comps three ways, cover & title direction, character & place names, the book-length sweet spot, reader vocabulary, market economics, risk flags and a step-by-step plan.
✨ New Every Map now includes a launch-video toolkit — the trending hashtags & sounds for your lane, ready for your BookTok and Reels.

Every Map is built from the same corpus — 12,200,000+ rows across the review, shelf, demand-signal and BookTok-video tables (demand signals are extracted from the reviews, so the rows overlap), read for your lane.
Free trope lists give you what was selling two years ago. A $15 Map sets the demand signals in your lane beside the titles already tagged with those tropes.
$15 to know if a book is worth three months of your life. A single bad trope decision — the wrong heat level, an over-published archetype, a setting readers have moved past — can cost an indie author months of work and a launch that disappears. A Map costs less than a paperback. It's the cheapest insurance against writing into a saturated lane, and the price per Map only drops as you buy more.
Every Map — whether you buy one credit or many — is built from the same corpus.
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. Method: How we count · how we count demand signals · how a Map is built.
