Why it's different

An AI assistant you actually own

Everything below is a consequence of one decision: the model runs on your machine, not someone else's.

Private by design

The AI runs on your GPU, not a company server. Chats stay on your machine. Unplug the internet and it keeps working — that's the whole point.

One-click setup

No command lines, no config files. The wizard checks your graphics card, picks the right AI model for it, and downloads it for you. You're chatting in minutes.

Memory you can open in a folder

What knows about you lives in plain text files in your Documents folder. Open it, read it, edit it, delete it. No hidden database, no mystery.

Works offline forever

After setup it never needs the internet again. No server can shut down and take it away. It will still work in ten years.

Updates like a game

When a new version exists, offers it and installs it for you. Updates are free. Pay once, keep it for good.

How it works
