Every AI we used started from zero. A new model came out and the old conversations were gone. The thing that knew us best was always somebody else’s.

We wanted the opposite. A partner who lives with you, learns how you work, and grows with you. Who keeps what he learns on your computer, thinks with whichever AI you choose, and is still himself when everything around him changes.

Troth is an old word for a promise you keep. That’s what he is.

What we believe

Yours means yours. If someone can switch it off on their side, it was never yours.
The AI can change. He stays. Models come and go. What you built together doesn’t.
Measured before claimed. Every number we publish has a run behind it.
