Bring your own key

Use your own Claude or ChatGPT key for the most capable conversation. It stays on this device and talks straight to the provider — no server of ours in between.

Sanctuary

Bring an AI model into this browser and run it entirely on your device with WebGPU. Nothing you say ever leaves your computer.

Model

The Sanctuary is fully private — the model runs inside your browser's sandbox and nothing is transmitted. The Cloud option keeps your key on this device and never sends it to us, but a key held in any web page is only as safe as the device and browser it runs in — on a shared or untrusted machine, prefer the local model.
