This is the best local llm manager in the market imo
Bayoikal 02
This one is a bit up there in price but from my experience this one doesn't skip a beat as far as the features are concerned and there are no bugs and errors involved unlike a great deal of others I've encountered. And the clean interface points out which models would rank out of memory for the models usage which is nice.
Developer Response
Thanks for the kind words, Bayoikal! We work hard to keep Secret AI bug-free with a clean, intuitive interface. So glad the memory indicator is helpful! Enjoy your private local AI experience! ⭐

I’ve been enjoying this app for quite sometime but I’m having an unfortunate issue.. the app crashes after 6-7 chats.. my guess is that the device runs out of memory.. please resolve this issue.. I’m using an iPhone 17 pro max ..

Excellent app, works great on my iPhone and M1 & M3 MacBook Pro. Surprised to see how well it works on my iPhone even in airplane mode. Great for everyone who needs an AI assistant for daily tasks. You can load up multiple models

Thanks for the great review! Really glad the offline mode is working well across all your devices. The airplane mode functionality is at the core of what we focus on, and we'll keep making the experience even better.
