About Fabbl
Fabbl (pronounced fah-bull) is a play on the word fable. It's an independent app for writing AI-powered interactive fables where you're the hero. The name predates Anthropic's Claude Fable 5 model — Fabbl is not affiliated with Anthropic. Fabbl uses frontier AI models the same way any modern app does: as an engine for the story you steer.
