  • AGPL-3.0-only. Free to use and change. If other people use your changed version, including over a network (for example a website you host for them), you must offer them your source code under the same licence. Using it privately for yourself or your household has no extra obligations.
  • Your data: stores no personal data. Language models under the user's local data folder and an optional SQLite file for API keys.
  • Other services: none required.
  • Reviewed version. Your AI always gets exactly the version we've checked.
  • Language models are large. Check disk and memory before loading many.
  • If you expose it publicly, enable API keys and rate limits.
