A secure, private desktop environment that runs alongside Windows. Isolated. Offline-ready. Fully under your control.
OOS is a complete desktop environment that runs alongside Windows. It brings its own file system, its own applications, and its own isolation layer — so your private space stays private.
Everything you do inside OOS lives in the Vault: a virtual disk, sealed away from the host system. Add a local AI assistant that works fully offline, and you get a computer inside your computer — one that answers only to you.
Its own virtual disk, sandboxed from the host. Your data doesn't leak into Windows.
Own browser, VPN, and tools — reviewed, sealed, and free from silent updates.
A powerful assistant that runs on your machine. No cloud. No leaks. Works offline.
No telemetry. No tracking. Your identity and files stay on your side of the line.
Start in seconds, carry it on a drive, run it anywhere — with no permanent host trace.
Built to evolve — modular apps, an open toolchain, and a clear path to full independence.
Gepardus is a powerful assistant living inside the Vault. It answers, writes, plans, and reasons — fully offline. Think of it as the New Ark of your knowledge: a durable, private library and collaborator that keeps working even when the network is gone.
We believe personal computing should belong to the person using it. OOS is a quiet, steady step in that direction — a place for your knowledge, your tools, and your daily life to live safely, without asking permission from anyone.
Early access is limited. Leave your email to receive lab updates and your invitation to the first waves of OOS.
