ChatGPT and Claude both have memory now. But they only know what you told them separately. Brain OS is the memory they share, so your projects, decisions, and ideas are there, in every tool, on every device.

You generate a Brain OS API key and add it to the MCP connector settings in each AI tool you use. It is a few steps per tool, not one tap. This is an early beta, so we will send you the exact steps to follow once your access is ready.
Your projects, your goals, your decisions. Talk to Brain OS the same way you talk to any AI. It takes notes, so you never have to repeat yourself.
Open ChatGPT on your phone. Switch to Claude at your desk. Pick up a conversation from last month. Brain OS makes sure both already know your story.
Connect it once to ChatGPT and Claude. Whatever you tell one, the other already knows. Your projects, decisions, and ideas are there on any device, in any tool.
