Ratings and reviews

Calling it the first accessible local AI app is a massive overstatement, but that's just marketing for you. The app itself is nice, having a good UI and being easy to use. Would recommend adding more models of different sizes to choose from in the future to allow people to balance between performance and quality of responses

A nice app that works well. Lovely UI too and being able to switch to a dark theme is great. The only little thing is when the response is being displayed it comes in bits and not all at once, if possible could be smoother. All in all a great and helpful app that works straight away.

Actually works as described. Installed and tried offline and had an interesting "conversation" to better understand AI!
