An open-source desktop application for running AI models locally, with a ChatGPT-style interface and support for connecting to remote APIs.

Why it is useful

One of the most actively developed open-source local AI frontends — the interface is clean enough for non-technical users while the underlying architecture is extensible for developers. The model hub makes discovering and downloading compatible models straightforward. Unlike proprietary local AI apps, the full source is auditable for privacy verification.
