Reddit Book Demand Analyzer

It's a free tool that scans Reddit communities like r/books, r/booksuggestions, and r/suggestmeabook to find real reader demand signals for any book genre or topic. It shows top posts, a demand score, top keywords, and AI-generated book opportunity insights.

Yes — it's specifically designed for authors, content creators, and entrepreneurs who want to validate book ideas before writing. Seeing what Reddit readers are actively asking for reduces the risk of writing a book nobody wants.

The tool searches Reddit posts from the past month, so you always get fresh, current demand signals rather than outdated trends.
