Jan is a proprietary-adjacent but already free desktop app for running AI models locally — it's actually open source itself (Apache-2.0). People searching for alternatives to Jan are usually comparing local-AI desktop apps, since several open-source options solve the same "run models on your own machine, keep data private" problem with different trade-offs in interface and features.
If you want a broader plugin ecosystem and multi-model chat, LobeChat and Open WebUI are strong alternatives. Cherry Studio is the closer match if you specifically want a native desktop client rather than a self-hosted web app, and AnythingLLM is the better pick if your main use case is chatting with your own documents.
