A massive, open library of AI character cards you can download or wire straight into your frontend.
Chub AI hosts hundreds of thousands of community character cards — portable definitions you can drop into SillyTavern, Agnaistic, or Chub’s own chat. It’s the de facto open registry for persona data, with tagging, versioning, and an API.
Who it's for: Roleplayers and frontend users who need a searchable, portable source of characters.
Download character definitions usable across many frontends.
Filter by fandom, style, model, and content rating.
Pull cards and metadata into your own tooling.
Track edits and roll back character updates.
If you run SillyTavern or any compatible frontend, Chub AI is the best open source of characters in 2026. Free to use; Pro just adds storage and sync.
