Everything included.

  • Boot anywhere.

    The same complete setup on any x86 PC. Your tools, your models, ready the moment it loads.

  • Everything pre-installed.

    Ollama, Llama 3, Mistral, Phi and more ship ready to run. No configuration, no dependencies to chase down.

  • Full speed. All the time.

    Local inference means your hardware is the only limit. No server lag, no throttling, no rate limits.

  • No account. No subscription.

    Plug in and work. Nothing to sign up for, nothing to pay, nothing to renew.

  • Open source, top to bottom.

    GPL licensed from the kernel to the chat interface. Inspect it, fork it, make it yours.

  • Works offline.

    No internet required. Take it to a plane, a cabin, a secure facility — it just works.

Flash & boot in minutes

Download the ISO, write it to a USB drive, and reboot. No installation, no partition changes.

  1. Download

    Grab the latest PAI ISO from the download section below.

  2. Flash to USB

    Use Balena Etcher (Windows/macOS/Linux) or dd on Linux/macOS:

    dd if=pai.iso of=/dev/sdX bs=4M status=progress

    On mobile you cannot flash a USB directly — use a desktop computer.

  3. Boot

    Plug the USB into your PC, reboot, and select the USB from your BIOS/UEFI boot menu (usually F12 or F2).

Frequently asked questions

What is PAI?
PAI is a bootable live-USB operating system that runs local AI models entirely on your own hardware. No cloud, no accounts, no internet required.
What hardware do I need?
Any x86-64 PC with at least 8 GB RAM and a USB 3.0 port. For running larger models (13B+), 16 GB RAM and a GPU are recommended but not required.
How do I install it?
Download the ISO and write it to a USB drive using dd, Rufus, or Balena Etcher. Then reboot your PC and select the USB from the boot menu. No installation to your hard drive is needed.
Is it really private?
Yes — not "policy-private," actually private. PAI never connects to the internet unless you open a browser yourself. All AI inference runs locally via Ollama. There is no telemetry, no license server, no accounts, and no company that can read your prompts, ever.
What AI models are included?
PAI ships with Llama 3, Mistral, and Phi via Ollama. You can add any GGUF-format model by copying it to the USB drive. The model library is fully under your control.
Can I use it without an internet connection?
Yes — that's the whole point. PAI is designed to work completely airgapped. Every component that needs to work offline is bundled on the USB drive.
Does it modify my computer?
No. PAI runs live from the USB drive and does not touch your hard drive or existing OS. You can remove the USB at any time to restore normal operation.
