From brooke.ltd, Belfast

Private AI that stays yours.

PrivateAI makes AI that works on your own computer, answers to you, and tells you plainly what it does and does not know.

Our principles The portfolio

What private means here

What we hold to.

  • Private

    Private by default and local first. Your AI works on your own computer.

  • Honest

    It says when it does not know, rather than guessing.

  • Yours

    You own your data. Only you delete it, and you can export it at any time.

All five principles
