LFM 3 on your phone: reasoning you can switch on or off, and a vision model that answers questions about your photos. Everything stays on the device.
Run open AI models like Llama, Gemma, and Qwen on your phone. Offline. Private. Free. No account, no tracking, no subscription. Powered by React Native ExecuTorch.
Meet Private Mind, the AI assistant that never phones home. Every conversation runs entirely on your device, so it works in airplane mode, on a plane, or anywhere the internet can't reach.
Why Private Mind?
· 100% offline: no internet needed, chat anywhere
· Total privacy: zero telemetry, your words never leave the phone
· Chat with your documents: import PDF or TXT files and get answers with clickable citations, so you can verify every source
· Model Hub: curated open models grouped by family, or import your own
· Built-in benchmarks: see how fast each model runs on your hardware before you commit
· Local speech-to-text: dictate prompts with Whisper, transcribed on-device
· Make it yours: custom system prompts, chat search, conversation forking and export
Models download once (about 1 to 3 GB each, best over Wi-Fi) and stay on your device. A modern phone with 4 GB+ RAM is recommended for larger models. Not sure? Run the built-in benchmark.
Free and open source. Verify the code yourself: github.com/software-mansion-labs/private-mind

I’m on iOS 26 on iPhone 12 mini. Even after the latest update, the keyboard covers the chat text field. Yes completely covered. I am totally unable to see what I am typing making the products. Well, I would call it unusable
Developer Response
Hi, thanks for the detailed report and sorry for the frustration. The keyboard layout has been reworked since version 1.1.4, and the text field now stays visible above the keyboard on smaller iPhones like the 12 mini. Please update to the latest version and give it another try.
LFM 3 is here.
• LFM 3 1.7B: reasons before it answers, in 16 languages.
• LFM 3 VL 2B: ask about your photos.
• The Think switch turns LFM 3 reasoning on or off.
• Steadier chats: a stuck answer stops on its own and offers a retry, and earlier reasoning no longer slows the next question.
• Fixes for mixed-language conversations and voice input.
