Janitor AI is a free AI chatbot platform for roleplay and storytelling, where you chat with millions of user-made characters or build your own. It runs on the web and mobile.
About Janitor AI
What Is Janitor AI
Janitor AI is a chatbot platform built for character roleplay rather than everyday questions. You browse a public library of user-made bots, open a chat, and write a scene with a persona that stays in character. It launched in June 2023 and now draws a large, active community.
The draw is freedom and price. Most platforms gate their best models behind a subscription, while this AI chatbot gives free accounts unlimited chats on JanitorLLM, its own built-in model, with no API key needed. You can also plug in an outside model through a proxy if you want GPT or Claude handling the replies.
The trade-offs are memory and stability. Free chats cap context at around 9k tokens, so long stories start forgetting early details, and because JanitorLLM runs on shared servers, replies can slow down when the site gets busy. Paid subscribers get five times the context and priority queues.
Getting Started
- Create a free account at janitorai.com, or download the app and sign in.
- Browse the character library by tag or search, then open a bot and start a chat.
- Write your first message in the style you want, since the bot mirrors your tone and detail.
- Create your own character with a name, greeting, scenario, and tags if you want something new.
- Subscribe to Janitor+ for more context and faster replies when the free limits slow you down.

Key features
Millions of User-Made Characters
The public library is the core of the product, filled with bots spanning fiction, fantasy, history, and originals built as one-off jokes. You browse by tag or search a name, and each character keeps its own voice and scenario.
Built-In JanitorLLM
Janitor runs its own free model, JanitorLLM, so you can start chatting without an API key or a paid account. It handles an AI character chat well out of the box, and free users get unlimited messages on JLLM, which is rare among character chat platforms.
External Proxy Support
If you want stronger models, you can connect a proxy and point Janitor at your own API key from providers like OpenAI, Anthropic, or OpenRouter. Power users use this to raise reply quality and context, and some free proxy routes cost nothing.
Character Creation Tools
Character creation is open to anyone, and no coding is needed. You set a name, greeting, persona, scenario, and up to ten tags, plus optional advanced fields like first messages and example dialogue. Finished characters can be published for the whole community.
Lorebooks and Custom Prompts
Creators can attach lorebooks and write custom prompts that steer how a bot behaves and what it remembers. This lets a character carry recurring world details or a specific speech style across a whole story instead of repeating them each message.
Janitor+ Router
The paid tier includes Router, which connects third-party models inside Janitor without a separate proxy setup and shows per-token pricing up front. It is web-only for now, aimed at subscribers who want extra model choice in one place.
Pros and cons
Pros
- Free accounts get unlimited messages on the built-in JanitorLLM, so you can chat for hours without a subscription or an API key.
- The character library is huge and community-driven, so new personas keep appearing across almost every genre.
- Character creation is open to everyone and supports tags, lorebooks, and custom prompts for deeper setups.
- You can connect your own API key or use the paid Router to bring in stronger models when you want better replies.
- The paid tier is a single low monthly price rather than a per-message charge.
Cons
- Free chats cap context at roughly 9k tokens, so long stories forget earlier details unless you pay for more memory.
- Because JanitorLLM runs on shared servers, replies can lag when the site is busy, and uptime has been uneven during heavy periods.
- Router is limited to subscribers and is web-only for now, so mobile users cannot tap it yet.
- There is no official public API for developers, so you cannot build the character library into your own app.
