Our Mission

We are building the
second brain for humanity.

Information overload is the defining problem of our age. We believe that by augmenting human memory with AI, we can unlock a new era of creativity and understanding.

User Agency First

We build tools that empower, not replace. The human mind is the captain; AI is the navigator.

Radical Privacy

Your thoughts are yours alone. We architect our systems to be local-first and private by default.

Speed of Thought

Friction kills flow. We obsess over milliseconds to ensure our tools move as fast as you think.
