Free AI tool for authors — generates book descriptions & keywords instantly

Spent years in Amazon KDP self-publishing and always hated writing book descriptions from scratch.

So I built PublishAI you enter your book topic, pick a genre, add keywords, and get a full book description, title ideas, and Amazon keywords in seconds.

It's completely free right now. No signup required.

Would love feedback from anyone here who writes, publishes, or knows authors who struggle with this. What would you add?

Doing one of these because I get more from reading what others are building than from any newsletter.

I'll start.
