FanChat vs Janitor AI
Janitor AI is a character chat platform where conversations run on a connected LLM backend: its own hosted model or an API key the user supplies. FanChat is also BYOA but supports six providers natively, adds a free local in-browser mode (WebGPU), tool calling, a community forum, and text-to-speech.

Frequently asked questions
Do FanChat and Janitor AI both require an API key?
Both can use a user-supplied API key. The difference: FanChat supports six providers natively with encrypted key storage and also offers a free local in-browser model (no key at all), while Janitor AI conversations run either on its hosted model or on the backend you connect.
Is FanChat an NSFW platform like Janitor AI?
No. FanChat moderates public characters according to community guidelines. In BYOA mode, content boundaries follow your chosen provider’s policy.
Which is better for private conversations?
FanChat’s local mode is the strongest privacy option of the two: Llama 3.2 1B runs entirely inside your browser via WebGPU, so messages never reach any server. Any platform that routes messages to a hosted model or third-party API cannot match on-device inference.
