What it is
A self-hosted chat interface that works with Ollama and OpenAI-compatible APIs, with accounts, history and document chat.
Good for
Giving yourself or a small team one clean chat screen across local and cloud models.
The catch
The license is custom, not a standard open-source one, so read it before you use it commercially. It is the interface only: you still need a model behind it.
