Quick Verdict
Best for safe, polished chat
Character AI
Huge character library, voice calls and polished mobile apps — but a strict filter that blocks mature and violent roleplay.
Best for tinkerers
Janitor AI
Allows mature roleplay and lets you plug in your own API key or proxy for better models — at the cost of setup and separate API bills.
Best of both
GPT Uncensored
Uncensored roleplay with no API key, custom characters and a story writer — ready in seconds.
Character AI Overview
Character AI (character.ai) is the biggest name in AI character chat, with millions of user-made characters, voice calls and apps for iOS and Android. It's free to use, and the c.ai+ subscription costs $9.99 a month for faster replies and extra features.
Its weak point for many users is the filter. Character AI blocks mature content and cuts off darker roleplay mid-scene. Since November 2025, users under 18 can no longer use open-ended chat, and the platform uses age assurance to sort adults from minors.
Janitor AI Overview
Janitor AI (janitorai.com) is a community character platform that allows mature roleplay. It has its own free model, JanitorLLM, and lets you connect an outside API key or proxy (such as OpenAI-compatible providers) for stronger models.
The trade-off is setup. Getting the best results means managing keys, proxy settings and separate per-token bills, and the free model can be slow or inconsistent at busy times.

Key Differences
Filters
This is the deciding factor for most people. Character AI's filter stops mature and intense content, and there's no setting to turn it off. Janitor AI allows mature roleplay, though how far it goes depends on the model you use.
Ease of use
Character AI works out of the box on web and mobile. Janitor AI's free model works without setup, but most regular users end up configuring an API key or proxy to get better replies.
Cost
Character AI is free with an optional $9.99 c.ai+ plan. Janitor AI is free to use, but if you connect a paid API, you pay that provider per message, which can add up during long roleplays.
Beyond text
Character AI has voice calls. Janitor AI is text-focused. Neither offers uncensored image or video generation.
Why Many Users Pick GPT Uncensored Instead
- Janitor-level freedom, Character-AI-level ease. Uncensored roleplay with no API key or proxy.
- One predictable price. Free credits to start, then a flat plan — no per-token API bills.
- Stories, not just chats. Build your own characters and turn your roleplay into long-form fiction with the story writer.
