Jan is an open source alternative to ChatGPT that runs 100% offline on your computer.
Supports both local LLM inference via HuggingFace and cloud model integration (OpenAI, Anthropic, Mistral, Groq), with an OpenAI-compatible API server on localhost:1337 for third-party app integration. Built on Tauri for cross-platform desktop deployment and Llama.cpp for efficient local model execution, plus Model Context Protocol support for agentic workflows.
