K-lytics, Publisher Rocket, Kindletrends, Romintel — what each covers, what each costs, and which is right for romance authors.
Indie romance authors now have a handful of dedicated market research tools, but they vary significantly in what they track, how current the data is, and what they cost. Here's an honest breakdown of the main options in 2026.
K-lytics publishes periodic genre reports covering Amazon bestseller data. The reports are thorough, but they're not updated consistently — typically every few months — which means the data is often historical rather than current. The coverage is broad (all of Amazon, not romance-specific), and the editorialising in their reports has been criticised by authors in the community for overstating confidence in the findings. Pricing starts at $37/month for the Premium plan, up to $97/month or $497/year for Elite.
Best for: Authors who want an occasional detailed genre overview and don't need daily data.
Publisher Rocket is primarily a keyword and category tool for Amazon listing optimisation. It helps you find the right categories and keywords for your book page. It doesn't provide genre-level signals like trope trends, subgenre price benchmarks, or cover analysis. It estimates book earnings, but those estimates have been contested by authors who can compare them against their own actual numbers. One-time fee of $199.
Best for: Authors focused on Amazon category selection and keyword research at launch.
Kindletrends tracks Amazon bestseller data and surfaces trending titles. It's broad rather than romance-specific, gives you a snapshot of what's performing rather than interpretation of why, and has no dedicated analysis layer explaining the behavioural economics behind what readers are doing. Pricing is $15/month, with the first month free.
Best for: Authors who want a quick look at what's ranking without subgenre-specific analysis.
Romintel is built exclusively for indie romance and romantasy authors. It pulls daily data from Amazon, Reddit, and Goodreads where it tracks the top 50 bestsellers across 8 romance subgenres, 24+ tropes, KU enrollment rates, median prices, cover analysis, and 7-day velocity signals. The key differentiator is the interpretation layer: rather than just showing raw numbers, Romintel explains why patterns are happening through a behavioural economics lens.
The market intelligence dashboard is completely free, although an account is needed for deeper analysis. A paid WIP Analysis tool launching in June 2026 lets you upload your manuscript and receive a full positioning report — subgenre fit, trope analysis, pricing recommendation, cover direction, reader psychology — at $29–$79/month.
Best for: Romance and romantasy authors who want daily, interpreted market data specific to their subgenre. Free.
If you need Amazon keywords and categories for your listing, Publisher Rocket is the right tool for that job. If you want broad trend data across all genres and don't mind the frequency, K-lytics or Kindletrends will serve you. And if you write romance or romantasy and want daily, subgenre-specific intelligence with interpretation — that's what Romintel is built for, and it's free to start at romintel.com/dashboard.
