Character.AI
Awaiting fact checkCharacter.AI is the largest general-purpose character chat service, built around a library of personas written by its own users. It is a mainstream product with mainstream moderation, which shapes almost everything about how it feels to use.
What it does well
- An enormous library, so almost any archetype already exists
- Web, iOS and Android, with the conversation following you between them
- Characters hold a recognisable voice across long sessions
What it gives up
- Moderation is strict, and the boundary has moved more than once
- No control over the underlying model or its settings
- Memory is modest next to products that sell memory as the feature

Janitor AI
Awaiting fact checkJanitor AI is a browser product organised around community-written character cards. Much of its appeal is that you can point it at a model of your choosing, which makes it powerful and makes the first hour harder than it needs to be.
What it does well
- Large community library with unusually detailed character cards
- Works with external models, so you are not locked to one provider
- Permissive about the kinds of stories people write
What it gives up
- Setup is a real step, not a formality, if you bring your own key
- Browser only, with no first-party mobile build
- Quality depends on the model you attach, so experiences vary widely
