Every tool starts from zero
Your notes live in one app, decisions in another, research in tabs. Every new AI politely pretends it’s meeting you for the first time.

One conversation, everywhere
SeKondBrain’s long-term mission is simple: wherever you are on the web or talking to an AI, it should feel like picking up the same conversation with your own knowledge.

From “new chat” to “continue”
Surfaces ask SeKondBrain for relevant concepts and past reasoning. Conversations start where you left off. New learning flows back with consent.

Three domains. One brain.
Inner knowledge, trusted ecosystems, and the external frontier. Most tools live in one domain. SeKondBrain is designed to connect them.

A portable concept profile
External tools won’t see your documents. They’ll see the concepts, constraints and reasoning you’ve approved for this context.

Insight that stacks
Past decisions, Graphs of Thought and constraints travel with you. Each session builds on the last instead of resetting.

Curious about what we’re building?
We’re developing a neurosymbolic Cognitive OS focused on meaning, reasoning, and shared understanding between humans and AI. If you’re interested in the architecture, the roadmap, or shaping this with us as a design customer, we’d love to connect.
