Free Fandom Generators
Small tools for people who make things up about characters. Headcanons, OCs, personalities, backstories, fanfic prompts. No account, no limit, no cost.
Almost every tool runs in your browser and sends nothing anywhere. The AI fanfic generator is the one exception — it sends your brief to an AI to write the prompt, and stores nothing.

A name, a role, a look, a personality, a quirk and a want — a whole original character, built from the world it lives in.

Why we built these
Rabu AI is an anime companion app. Characters that remember you, images, voice, and branching stories you play rather than read.
These generators are the bit that comes before that. They are free and they stay free, whether or not you ever make an account. If one gives you a character you like, the app is where they start answering back.
