About Jan

Jan is an open-source desktop AI chat application designed for individuals seeking a privacy-focused alternative to ChatGPT. It enables users to run large language models entirely offline on Windows, macOS, and Linux by downloading open models such as Llama 3, Gemma, or Mistral from Hugging Face, or importing GGUF models. For scenarios requiring cloud-based inference, Jan supports connections to providers like OpenAI, Anthropic, and Groq using API keys. The application provides a chat interface with adjustable model parameters and session context, along with real-time web search capabilities. Jan exposes an OpenAI-compatible local API (localhost:1337) powered by the Cortex engine, facilitating integration with other tools such as Continue.dev. The tool is particularly notable for its support of 100% offline operation after initial setup, making it suitable for air-gapped and high-security environments without data telemetry or internet dependency, while still offering optional cloud model connectivity when needed.
