MNN Chat is a clean, fast, and surprisingly capable AI chat app. Responses are quick, the interface is simple, and it’s easy to jump in and get useful answers without any friction. Great for everyday questions, ideas, and quick problem-solving. 5/5 - simple, fast, and actually useful.

A fantastic app for downloading and running LLMs locally. The app is simple enough for basic users - just tap download and tap the model to chat (I recommend the Qwen models which are also by Alibaba like the app makers). For more advanced users, various settings are adjustable, you can import your own MNN quantized model, and the app even ships an OAI-compatible API if you want to plug it into Open Web UI, etc. Keep up the great work MNN team 👍

Not ready yet (Feb 2026). Multiple issues. 1) Downloading models seems to break most of the time, with an error on header download at the end. 2) Even if the download breaks, the files seem to be stored on your phone. I have several models downloaded, but the app is using over 100 GB of storage. 3) The only image generation model is laughable and slow. Maybe try again in a few months.

Chat are good but I have complained about big size file voice chat because it's crash on my phone can be possible to have lite versions. Calls crash. I have a lot of unrecognizable voice calls and slow bug trouble. Don't work offline translator mess the words and get dumber to understand things.

Useless for simple offline gguf models users, because there is no option to simply run an already downloaded model in mnn chat app like pocket pal app, uninstalling the app.
