Tropesmith is a trope research tool for romance authors. It counts demand signals, the specific things readers name or praise in reviews, comments and posts, trope by trope, then sets your trope stack beside what the shelf already supplies. One Map costs $15, falling to $10.50 each at 11 or more credits, and credits never expire.
Choosing tropes by instinct, or by what was selling two years ago, is how a book lands in a lane that has moved on. A trope research tool should do three things: count which tropes readers actually name, keep that separate from what is already on the shelf, and put a date on its counts so you know how old they are.
Tropesmith counts demand signals: one specific thing a reader asked for or praised in a review, a comment or a post, picked out by Tropesmith’s classifier and tagged by trope. Each signal also carries a rarity tag, and the share of a trope’s signals tagged underserved or novel by Tropesmith's classifier points at where to look. The tag is judged from each review or post alone, so it does not prove that no book answers the signal.
You can read the open version for free: the romance tropes list ranks the main romance tropes, the romantasy tropes page does the same for one lane, and the book tropes list covers every genre. The method page explains how the counting works.
A Tropesmith Map scores your exact trope stack against the demand signals in your lane and the titles already tagged with those tropes. It returns a go/no-go opportunity score, a ranked trope stack with demand set against supply, comp titles, cover and title direction, the book-length sweet spot, reader vocabulary, market economics and a step-by-step plan.

Publisher Rocket and Tropesmith overlap very little: Rocket is for the listing, Tropesmith for the decision about what to write. K-lytics reports give a written view of a whole genre, while Tropesmith gives counted demand per trope. TrendFyre also follows trope movement over time.
It is not a keyword tool and gives no Amazon search volumes. It does not track sales book by book, though a Map includes lane-level earnings estimates. It does not write or draft your manuscript. If keywords, categories or ads are the job in front of you, use a tool built for that.

For trope-level demand, Tropesmith counts the demand signals readers leave in reviews, comments and posts, trope by trope, and puts a date on its counts. You can use both, because one finds the book's listing and the other helps decide which book to write.
One Tropesmith Map costs $15 in US dollars. Buying more credits lowers the price per Map: $13 each for 2 to 5, $11.50 each for 6 to 10 and $10.50 each for 11 or more. Credits never expire. A Live Board add-on, which keeps a bought lane's counts refreshed, is $7 a month. A free Lite Map and several free tools need no card.
Yes. Tropesmith's free tools include the Trope Demand checker, Trope Pairs, Lane Score and Trend Radar, and the free Lite Map shows your subgenre's opportunity score before you spend anything. They give you counted demand at teaser depth; the paid Map goes deeper for your exact book.
A count of demand signals says a trope is talked about at scale. It does not say how many books already cover it, or whether your angle is the one readers want. Tropesmith also does not track sales book by book or give Amazon search volumes, so check comp titles before you commit.
