The system disk is read-only and cryptographically verified. Updates are signed with post-quantum cryptography. And the built-in AI can't do anything without your say-so. Your machine answers to you, not to a data centre.

Why Orynr exists
Most “AI PCs” bolt a chatbot onto an old stack and send your life to somebody else's servers. Most hardened systems ask you to give up everything that makes a computer pleasant to use. We didn't want to accept either trade, so we built Orynr.
The AI runs locally. Your data and the system's diagnostics live in separate planes. Owner control is tied to your credentials and written to an audit log, so there's no hidden way in.
The system disk can't be modified, and it's verified every time you boot. Underneath sits a kernel we harden and compile ourselves, with defences that reach into the kernel itself.
The assistant does real work on the machine. It also can't take a single privileged action until you approve it. That's a property of the design, not a promise we're asking you to trust.
Have a look around
Each of these has a page of its own, written to be read rather than skimmed.
Ora
Ora reads files, runs scans, changes settings and investigates problems. Every privileged action raises a consent card first, and every one is logged. It runs against a model on your own hardware, so no prompt and no file leaves the machine.
Security
Verified boot, a kernel built from source, a firewall that watches program execution inside the kernel, mandatory access control, files judged by their contents rather than their names, and post-quantum signed updates.
Technology
Mainline Linux LTS with the hardened patch set and our own configuration, compiled with whole-kernel link-time optimisation. An immutable verified base with your files kept separate. A desktop written in Rust for this operating system.
The desktop
Seven themes, a clean light one by default, and a shell written from scratch for this OS.






Write the 456 MB live image to a USB stick and boot from it. Everything works, so poke around, break things and change your mind. Nothing is written to your computer.
Orynr_OS is in active development. Features carry a label Shipping New Architected throughout this site, so you always know what is real today.
