JanitorAI is a browser-based AI chatbot platform that enables users to create and interact with fictional characters. It allows integration with large language models (LLMs) like OpenAI and KoboldAI, and offers its free default model. The focus of the platform is not utility or productivity but user-defined conversation.
This review outlines JanitorAI’s actual capabilities, supported features, pricing structure, languages, and technical constraints. No assumptions or marketing language — just an assessment of how it functions in real use.
JanitorAI is not positioned as a productivity tool. It does not provide structured output like summaries, reports, or search-based results. Instead, it supports open-ended text-based conversation between users and AI characters.
These characters can be designed manually or selected from a public gallery. Interaction styles range from casual to fantasy to NSFW, depending on user settings. The platform is used mostly for entertainment, dialogue experimentation, or roleplay.

JanitorAI offers a framework for custom AI character interaction. It does not guide user experience and places the burden of content quality, safety, and stability on the user. While functional for creative or exploratory use, it lacks the reliability and structure expected in commercial AI tools.
Users considering JanitorAI should be aware that the platform is self-service in nature, with minimal built-in support, moderation, or error handling. Its effectiveness depends heavily on user input, API setup (if used), and system availability.
I’ve been using Janitor AI for a few weeks, and it’s fun to interact with different characters. The customization is cool, but sometimes the responses feel a bit off. Overall, a great tool for creative chatting.
