AI tools are exploding. But which ones actually work? This book maps 6,494 verified AI engines across 69 categories — from research and writing to image, video, code, and beyond. Built on the GAIT 69 taxonomy (DOI: 10.5281/zenodo.20248631), every entry is verified and categorized by a human researcher, not scraped. Available on Amazon Kindle ($9.99) and Paperback ($19.99). Also on Gumroad with full database access bundle.

Hi Product Hunt! 👋

I'm Do Hun Kim, a Korean independent researcher and developer.

I spent months manually verifying and categorizing 6,494 AI engines
into 69 categories — what I call the GAIT 69 taxonomy.

This book is the result. Not scraped. Not AI-generated.
Every entry checked by hand.

I also built the AI MAP app (already on PH!) that lets you
explore this database interactively.

Would love your feedback — especially from anyone who's tried
to keep up with the AI landscape and felt overwhelmed.
That's exactly who this is for.
