About Third Ark
THIRD ARK

We build small, sovereign AI.

Offline language models that live on a USB, speak your domain, and never leave your control.

Our Story  

Third Ark began at the intersection of **Palantir’s data vaults** and **ancient monasteries.  

Our founders saw the same pattern:  

  • Defense contractors couldn’t risk cloud AI with classified docs.  
  • Orthodox catechists needed the Fathers without secular hallucinations.
  • Homeschool parents wanted a tutor that respected their curriculum.  
  • The solution was identical: a private, air-gapped brain on a keychain.

What We Believe  

  1. Privacy is non-negotiable — even anonymised telemetry is a leak.  
  2. The best AI is small — 2B parameters beat 70B when trained on your data.
  3. Digital tools should feel physical — a USB is heirloom, not a subscription.
