Free Fandom Generators
Small tools for people who make things up about characters. Anime characters, waifus, headcanons, OCs, quirks, Stands, cursed techniques, fanfic and spicy stories. No account required.
The tools marked written by AI send your brief to an AI to write the result, and the anime character and waifu generators send the look you picked to draw a portrait. Neither stores what you sent. Every other tool builds its result in your browser.

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.
