ChatTutor is an open-source AI tutoring application pairing conversational AI with teaching tools including a maths and drawing canvas and mind maps, for one-to-one study sessions. Self-hosted deployments set a model API key environment variable and a provider selector for OpenAI, Anthropic or DeepSeek, and the hosted instance asks users to set their own key and models in settings. Self-hostable web app. AGPL-3.0, 1,306 stars, last commit about seven months before review.

Why this trust score (74/100)

Trust measures how the tool treats your API key and how much of that has been verified. It contains no popularity signal.

How your API key is handled

You self-host the app, so your API key lives in your own deployment. Requests are sent directly to the AI provider. Because it can be self-hosted, your key never has to touch a third-party backend.

Setup

Deploy it (Docker/compose), add your provider API key in the admin or environment config, then select models.
