Cobrain

Every new chat means explaining your work again. Switching AI tools or bringing in a colleague makes that context even harder to keep. Cobrain gives you a shared memory in Markdown: decisions, project details and working instructions that you and your AI assistants can read and update. Connect Claude, ChatGPT, Claude Code or another MCP-compatible client, then keep useful context in one place across conversations and tools. You stay in control of the notes. Browse folders, edit Markdown, search, use tags and restore previous versions. Share a folder or a single note with a colleague: it becomes available to them and their connected AI, with the permissions you choose. Export your notes as Markdown whenever you want. Cobrain works with the AI you already use. It does not generate answers itself or require you to switch to a new chatbot. Start free with one brain, up to 1,000 notes and three read-only shares. Pro adds unlimited notes and brains, write sharing and attachments. Team brings Pro to your team with centrally managed seats.
