Janitor AI

Janitor AI is a web-based platform for creating and chatting with custom AI characters. Users build chatbot personas with defined personalities, backstories, and appearances through a character creation panel, then converse with them in a chat interface that supports text streaming for a more natural back-and-forth feel. Conversations can run on Janitor AI's own built-in model, JanitorLLM, or on external language models that users connect using their own API key, commonly from providers offering OpenAI-compatible or open-source models. A public library of user-submitted characters is available to browse and chat with immediately, alongside tools such as scripts and lorebooks for building and publishing original characters, including support for custom CSS styling.

Because response quality and cost depend on the connected model, users can choose between free, lower-cost, or premium options based on their needs, and a Pro subscription is available for members who want higher message limits on the built-in model without managing external API keys. Janitor AI restricts access to users who are 18 or older, permanently bans accounts reasonably suspected of being underage, and applies extra age verification steps in certain regions. The platform provides adjustable content and safety settings that let each user set boundaries for their own conversations. Janitor AI is aimed at people interested in interactive storytelling, character roleplay, and companion-style chat rather than business or productivity use cases.
