A cross-platform desktop client for chatting with many model providers and local models from one app.

Chatbox is a desktop client that puts your own provider keys, or a local model, behind a clean chat window. It runs on macOS, Windows, and Linux, and keeps chat history on the device.

It is straightforward by design — a personal tool rather than a deployable platform — which is exactly its appeal for an individual who wants one app for every model.

Where it's ideally used

Best for an individual who wants a single, simple desktop client across several model providers.

Where it doesn't fit

Not a deployment platform — there is nothing here for shared accounts or central administration.
