Ratings and reviews

Promising but not stable. I used this locally offline with some success. I like the design best of the local llm apps Ive tried. Not perfect but nothing is. Unfortunately every week or so, the downloaded models just disappear. Annnd I have to find and download each model again; on wifi it is not convenient, but a deal-breaker on mobile data... This happens consistently enough that I gave up after 5-6 times. It also loses the chat history.

The best Local AI app I have tried on Android, so far. it's clean quick and functional.

It's a desperate shame. This app has so much going for it, it's one of the best laid out and well designed local LLM apps around. BUT it has a CRITICAL bug which will have you pulling your hair out: EVERY model you download within it WILL BE AUTOMATICALLY DELETED BY THE APP AFTER A FEW DAYS! That's many gigabytes of data down the drain each time, plus the long time it takes to download them! I've raised it repeatedly for months with the author, but no response! It's so sad, I can only say AVOID!
