We're solving the intelligence trilemma: balancing intelligence, speed, and cost.
Living Brain is our AI memory layer, helping models remember and carry knowledge across tools. ChatChat is our no-code workspace to use Living Brain easily.
This is the 2nd launch from ChatAndBuild. View more
Living Brain
Launching today
Every AI conversation contains knowledge worth keeping, but most of it gets trapped in separate chats and tools. Living Brain captures that knowledge, connects it to what you already know, and turns it into a persistent memory that keeps evolving. Share that intelligence across AI models, apps, and agents through API, SDK, or MCP, so every new interaction builds on the last instead of starting over.
Reuse memory across ChatGPT, Claude, Gemini, OpenClaw, Hermes, Cursor, Codex and more

We built Living Brain because no one should feel stuck with one AI tool just because all of their context is there.
You should be free to try what is new, use what works best, and switch when you need to, without starting from scratch each time.
Your memory should be yours, and it should travel with you.
My current workflow is a lot of jumping b/w references, random ideas, feedback, and last-minute changes. Because of Living Brain, I can come back to an idea later w/o losing the thought process that made the it click. I get to spend more time actually creating instead of retracing how I got there.
Living Brain helps to solve a frustration that many of us know firsthand: having to repeat the same context every time we switch AI tools. For me, knowing that I can carry my notes, decisions and project context across compatible tools makes it easier to choose the right AI without starting from scratch, and this is exactly the advantage that Living Brain gives you!
You can create a Brain in ChatChat without code, or connect Living Brain to your apps through our API, MCP, SDK and CLI.
I’m excited to share what we’ve built and would love to hear how it helps you!
Being able to inspect the sources behind a memory matters as much as carrying it between tools. I'd want to trace an old decision back to its source and correct it once when the project changes.
