Loved by users
"I have sampled many offline LLM apps and I got to say that for the money this app has a lot of punch. It is feature rich with an innovative interface. It gives you almost full operational control. Very cool. It's a complete package."
"Tons of options and a clear walkthrough of how to best set up the app. Lots of AI platforms offered to pull into the experience. Really versatile, and smooth UI. Great tool!"
"The app is well designed and works smoothly. I like that everything runs on my device with privacy in mind. It handles chats and images easily."
"I was deeply impressed by how incredibly fast and kind he is. I believe this is a very promising application with great potential. I highly recommend it!"
"I am using it from past few days.. it has been the best experience.. the best thing is that everything is running locally."
"I used the test flight for this and was very impressed. On my 13 pro max I was able to quickly generate responses with 3b models. Other apps I've tried seem to fail or take forever."
"I've been using this on my iPhone 17 Pro Max for a good while, and I must say, the macOS version of this does not disappoint! This is one of the best local AI tools I've ever seen, and with the price, you just cannot go wrong! Excellent job!"
