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

Using an IDE like Claude Code, Cursor, or Zed? BrainOS is open source and works today. Install it now →
Every tool connects with OAuth sign-in. No API keys and no secrets to paste. ChatGPT and Grok take the BrainOS URL; Claude takes the URL plus one public client ID in its connector settings. It is a few steps per tool, not one tap. We send the exact steps when your access is ready.
Your projects, your goals, your decisions. Talk to BrainOS 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. BrainOS makes sure both already know your story.
Connect it once to ChatGPT, Claude, Grok and more. Whatever you tell one, the others already know. Your projects, decisions, and ideas are there on any device, in any tool.

You told ChatGPT about your project this morning. Now you open Claude. Watch what happens.
I want to think through the monetization for my app.
Happy to help! Could you tell me a bit about the app you're building and who it's for?
I already explained this to ChatGPT this morning... it's a travel planning tool focused on experience quality, not cost.
I don't have access to your ChatGPT conversations, so I can't see what you shared there. But based on what you just told me, a travel tool focused on experience quality...
✕ You started over. Again. The context was already there, just in a different AI.
I want to think through the monetization for my app.
Since your travel tool prioritizes experience quality over cost and that's the core insight, a few angles worth thinking through:
Premium tier makes sense. Users who care about experience quality will pay to avoid trade-offs. The question is what the free tier looks like without undermining that.
✓ No re-explaining. Claude picked up exactly where ChatGPT left off.
