Nothing you say ever leaves home. … runs a real AI model on your own graphics card. No subscription, no cloud, no account, no one reading your chats.
Everything below is a consequence of one decision: the model runs on your machine, not someone else's.
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.
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.
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.
Share a folder with a chat and … can read, search and organise what's in it — "put the photos in one place", "what's in these files". It asks before every single change, sends anything it removes to the Recycle Bin, and there's an undo button. Off until you turn it on, and limited to the folder you pick.
After setup it runs offline day to day. No server can shut it down and take it away — it's built to keep working even if we disappeared, and it'll still work in ten years.
When a new version exists, … offers it and installs it for you. Updates are free. Pay … once, keep it for good.
Three steps, and only one of them takes any real time.
One-time purchase of …. You get the Windows installer immediately.
Run the installer like any other program. On first launch, the wizard detects your GPU and downloads the best AI model for it.
From then on, … starts like a normal app and answers from your own hardware — online or offline.
Read these honestly. We'd rather lose the sale than have you refund a disappointment.
