Will you answer
the call?

We saw where Big Tech was heading and we weren't having it. So, we've built an AI built on privacy, community, sustainability and transparency. One that puts you and the planet first.

And for those who say "it can't be done"... or "it won't be as good as Big Tech's stuff" We have and it is.

Just try it.

For Your Eyes Only

We will never use your conversations with GB1 to train our AI models or profit from your data. Your conversations are private to only you. Your data and conversations with GB1 are end-to-end encrypted, stored only on UK resident servers, and protected by UK data privacy laws.

GB1: Because what you ask an AI is your business.

We design and
build sovereign
foundational AI

Locai Labs was founded on a clear mission: to build independent and sovereign foundational AI. We saw an industry dominated by a handful of closed systems, prioritising profit over people. We believed there had to be a better way and we set out to build it.
