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.

Character.AI is a chatbot platform that lets users create and converse with customizable AI characters. Launched in 2022 by former Google researchers Noam Shazeer and Daniel de Freitas, the platform allows anyone to build a character by defining a personality, backstory, greeting message, and example dialogue, then publish it for others to chat with. Millions of user-created characters are available on the platform, ranging from original creations to characters based on fictional stories, historical figures, and other public personas. Conversations happen primarily through text, with users able to rate responses to help refine how a character behaves over time. The platform also supports Rooms, where multiple characters and users can interact together in a shared conversation.

Beyond text chat, Character.AI offers Character Calls, a voice conversation feature built on more than a million community-created voices and available in numerous languages, and Scenes, which places users into structured, guided roleplay scenarios with preset environments. A free plan provides access to core chat features, while the c.ai+ subscription, priced at $9.99 per month or a discounted annual rate, adds priority access during busy periods, faster response times, expanded memory, unlimited voice calls, and an ad-free experience. As of late November 2025, Character.AI restricted open-ended chat for users under 18 as part of a broader set of safety changes. The platform is aimed at users interested in interactive storytelling, roleplay, and conversational AI companionship.
