Everything below runs on the same engine our paid Maps run on, and every one of them is free to use. No sign-up wall, no trial clock, no credit card. If you only take one thing from this page, take the lane score for the subgenre you are about to write in.
Type any genre and any trope, see the counted conversation volume: mentions, share of the genre, rank against every other trope published for it, and whether its share of the genre went up or down. No signup to see the read.
Check a trope →This shows trope pairs named together in demand signals against the number of published titles that carry both — two counted numbers side by side, lane by lane.
Compare the pairs →Everyone says “use BookTok hashtags”. This ranks the book hashtags in each lane by their share of the on-tag BookTok videos we sampled, with the number of videos scanned, each figure stamped with the date it was scanned.
Pick my hashtags →Pick your subgenre and see tropes near the top of the lane’s ranking by likes and upvotes on the posts behind their demand signals (no view of the shelf).
Check my subgenre →Which tropes romance readers name and praise, lane by lane — counted from demand signals in Goodreads reviews, BookTok comments and captions and Reddit posts. See which tropes readers mention most.
See demand signals →Every romance lane, ranked by one Green-Light verdict — so you compare lanes by one score instead of a hunch. Blends demand signals, lane economics and pricing health into a single score per lane.
See every lane ranked →Paste an Amazon link or ASIN and see every category that book ranks in and where it sits in each one. The free, always-updated replacement for the retiring BKLNK category checker.
Check a book →One number that answers “is this subgenre worth writing?” — opportunity score and rank, greenlight band, typical list price, Kindle Unlimited share, 30-day demand signals, the heat level readers expect and the length that sells. Available as a page or as JSON.
Score my lane →One script tag puts a live lane board on your site — your blog, your newsletter template, your author page — and it refreshes daily. No libraries, nothing to maintain.
Get the snippet →An auto-refreshed economics page for every lane we cover: typical price, Kindle Unlimited share, and how many new titles are entering.
Browse the lanes →Know how readers react to a hook before you post it, instead of finding out from a flat launch.
Try a hook →Why readers put books like yours down — read out of the complaints real readers leave on books in your lane.
Run the radar →Two complete Maps, free to read end to end, so you can see exactly what you get before you spend anything. See pricing for what a Map costs.
Read a full Map →A weekly read of the week-on-week change in each trope’s share of a lane (a hint, not a trend), and what it means for the book you are drafting.
Read this week →The Live Board is embeddable, free, and free to use commercially. Paste this where you want the card:

The only condition is attribution: keep the visible “Data: Tropesmith” credit link back to tropesmith.com. Do not strip it, hide it or nofollow it — that link is what pays for the data. Full options, themes and the iframe version are on the embed page.
Counted, not estimated: 5,070,000+ Goodreads reviews, 4,120,000+ shelf signals, 2,860,000+ demand signals and 145,000+ BookTok videos across 760+ tracked hashtags. Separately, 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). The registry holds 670,000+ titles, 142,000+ of them tagged trope by trope across 5,130+ distinct tropes and 140+ demand lanes. Nothing on this page is a guess or a round number typed in by hand. The demand signals figure was counted 2026-11-05 10:15 UTC; every other 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
These tools answer one question at a time. The 2026 Romance Demand Report answers the whole year at once — which tropes romance readers named and praised. Free, from the same engine.
