The user interface could use a little work. I would love it if they added a space to add a PDF file. Enjoyable product great read back. would love the option to choose different voices even if it was a paid option. I like the fact that I can use other models in upload. Absolutely worth the download if you're playing with private artificial intelligence building.

Thanks! The voice can be set up in your phone's Text to speech settings if it allows it.

I have a problem, it always says "Model failed to load" even though I have enough RAM and disk space. I have tried all the free models and they all have the same error, I have also reinstalled the app multiple times. Please help. EDIT: The developers suggestion didn't work, but I'm pretty sure it's because of my device. I'll try the app again when I get a new phone which should be soon. Until then I'll give it three stars.

Pretty solid basic app for local ai. The addition of something like JSON file save and load would be appreciated, or some other way of reloading the chat - when I leave to use other apps and come back sometimes previous chat is there, sometimes not, and not the best way of reloading. That said it's easy to use (much easier than the termux method), and easy to add other gguf models. Slower than pc, obvs, but useable. It's a boon for creative writing and creating characters or just general facts
