Ratings and Reviews
Robust Framework, Except need for Experience Improvement
So far it’s been a very good catalogue of integrated models, and recent add of the DeepSeek variants is even more appealing. Few areas of improvement, especially in saving chats or for the system to automatically save each chat session or have user save them and be able to return to them in future. Currently it is quite annoying to loose chats that have started, only to start rebuilding the whole context again. Also providing a means to base saves chats to specific Models will be a very good. Can’t wait to see or experience the next update. So far so good, but missing features elaborated make it. A tertiary app compared to others i use as a default. Perhaps these updates when done could change that.
Developer Response ,
Thank you for your support and suggestions! That’s really valuable feedback. I’ll try to work on improving the chat experience in future updates. Please continue to support us!
Best local AI on iPhone
I honestly can’t fathom how this app is free. It’s like stumbling upon a treasure chest in a sea of paid apps that don’t even offer a fraction of these features. The fact that you can run AI models locally, with this much precision and functionality, is mind-blowing. Meanwhile, so many “premium” apps charge a hefty price for far less.
Now, about the negative reviews—let’s address the elephant in the room. If your 6GB iPhone can’t handle an 8B model, that’s not the app’s fault; it’s basic tech knowledge. Calling the app a “scam” because of hardware limitations is akin to blaming a sports car for not fitting in a bicycle lane. Let’s be real: you wouldn’t try to cram a piano into a shoebox, so why attempt to run a high-performance model on a device not equipped for it?
This app is a gem, and any criticism rooted in misunderstanding is just noise. It’s evident that the developers behind this masterpiece know their stuff, and the fact that it’s accessible to everyone at no cost deserves applause. If you’re into cutting-edge AI and have the right hardware, this app is a game-changer. Don’t sleep on it!
Shortcuts compatibility is awesome!
The ability to make a shortcut that allows for running an LLM in the background is great. Do you believe that there are any extra features you can add for shortcut compatibility? For example: - Defining a system prompt - Continuing a conversation - Defining a preset conversation (to be used as synthetic context) then generating a response to the defined conversation ... all in Shortcuts :D There are just a few problems, however. I've come to find that a message may just stop generating out of the blue, and that in Shortcuts, generated responses from the same query are always the same. Aside from these minor issues, thank you so much for implementing this feature, I can see many practical shortcut workflows coming up in the near future, and maybe you could even put together a community of Shortcut users where they show off cool little applets and masterpieces through the power of prompt engineering!
