 Free

Free and open source. Using a third-party cloud model through Jan costs whatever that…

Self-hosted, Web Windows, macOS, Linux
  • One interface for local Ollama models and any OpenAI-compatible API
  • Document upload and retrieval so you can ask questions about your own files
  • Runs fully offline on your own computer when you want it to
  • Same interface for local models and for OpenAI, Anthropic, Google, Mistral and others
  • The licence adds a branding condition, so it is not plain BSD
  • It is a server you have to run, update and secure yourself
  • Still pre-1.0 and moving fast; features appear and change between releases
  • Adding a cloud provider means putting that provider’s API key into the app
