LearnHarness is an open-source desktop app that uses AI agents to teach difficult subjects by adapting to what a learner already understands. Rather than delivering a fixed explanation, it first probes the learner’s knowledge, confidence, and reasoning, then builds a visible path from that starting point to a chosen goal. Lessons proceed in small steps: learners predict, receive explanations, and check their understanding, with misunderstandings addressed before later concepts depend on them. Separate practice sessions use varied problems to help learners retrieve and apply ideas without being told which concept to use. Learners can explain their thinking in text or dictation, while the agent can research questions, create visual explanations, and build interactive demonstrations.

Learning accumulates in a persistent knowledge graph of propositions and the reasoning chains connecting them, linked to the sessions where they arose. Later lessons and practice can draw on this record, which stores ideas rather than scores or ability ratings; users can also import notes. The app runs on macOS, Windows, and Linux and supports more than 30 model-provider options, including OpenAI, Anthropic, Google, DeepSeek, and OpenRouter. Users supply their own provider keys and pay providers directly, with a cost meter available. Chats, settings, keys, and learning records are stored locally, but model requests and optional web research or dictation use external services. The AGPL-3.0 code and editable system prompts make its behavior inspectable; development tests run without an LLM or network.
