Truly on-device
Models run locally on Apple silicon. Your prompts and replies never touch a network — because there is no backend to send them to.
AI that never
leaves your iPhone.
Mura runs powerful open language models entirely on your phone. No sign-up, no subscription, no servers — your conversations are yours alone, and they work even in airplane mode.

Privacy by architecture
Your conversations never touch a server.
There is no server.
Mura has no analytics on your chats, no cloud sync, and no telemetry on what you say. Privacy isn't a setting you toggle — it's the way the app is built.
Frequently asked questions
Everything you need to know about running AI privately on your iPhone.
What AI models does Mura support?
Mura supports leading open models including Meta Llama 3.2, Google Gemma 3, Qwen3, Microsoft Phi-4 mini, Mistral 7B and SmolLM3 — and Apple Intelligence on supported iPhones. Every model you download runs completely offline on your device, and the catalog keeps growing.
Does Mura work without internet?
Yes. Once you've downloaded a model, Mura works completely offline — on a plane, underground, or anywhere with no signal. The only time a connection is needed is the one-time model download. All chatting happens locally on your device.
Is my data private and secure?
Your conversations are processed entirely on your device — there's no account, no cloud sync, and nothing is ever used to train a model. The only data we collect is anonymous, aggregated usage and crash diagnostics to improve the app, never the content of your chats. See our Privacy Policy for the full detail.
What devices are supported?
Mura is built for iPhone and optimized for Apple silicon. It runs on iOS 26 and later; larger models need a more recent iPhone with enough memory, so Mura's catalog tells you exactly which models fit your device. The built-in Apple Intelligence option requires an Apple Intelligence-capable iPhone.
How do I run an LLM locally on my iPhone?
Download Mura from the App Store, pick a model to download (or start instantly with Apple Intelligence), and begin chatting. There's no account creation and no login — just download and use.
Can I customize the AI's behavior?
Yes. You can adjust generation settings such as temperature and maximum response length to shape how the model replies, and switch between models at any time to change the assistant's style, speed and capabilities.
