How to use Janitor AI?
To use Janitor AI, go to janitorai.com, create a free account, confirm you are 18 or older, then browse or search character bots, click one, and start typing. As of 2026-07 the built-in JanitorLLM model is free and needs no download or API key to begin chatting.
Why — the first-principles explanation
Janitor AI is a character-chat platform: thousands of user-made AI characters, each defined by a written profile, sit on top of a large language model. When you send a message, the model reads that character's profile plus your recent conversation and predicts a reply that stays in character. Everything runs on Janitor AI's servers, so your browser is the only tool you need.
Because the platform is free at the core, the first-time flow is deliberately light: make an account, confirm your age, and pick a bot. There is no software to install and no key to paste for the default model. You only add an API key or proxy later if you want a faster or different model than the built-in one.
The last layer is personalization. You can turn NSFW content on in settings after an age check, save favorite bots, and even build your own character. None of that is required to start, which is why most people are chatting within a minute of signing up.
An example that makes it click
Using Janitor AI is like walking into a giant costume theater where every actor already knows their role. You buy a free ticket (make an account), show you're an adult at the door, then pick any actor from thousands on the wall. You say a line, and the actor answers in character, remembering the last few things you said. You didn't hire the actors or write the play; you just walked in and started the scene.
