TeamBrain is where your team and your AI tools actually work together, instead of your best thinking getting stranded in a single chat window. Every doc, task, deadline, and decision lives in one connected workspace, written in plain markdown so any AI, Claude, ChatGPT, or anything that speaks MCP, can plug straight in and read or write to it. Kanban boards, a shared calendar, doc comments, and a daily "what's on your plate" email keep the whole team in sync, while every meaningful change gets logged with the reasoning behind it so nothing important disappears into their chat history. A contractor or new hire opens TeamBrain and gets the full picture in one sitting. You keep working exactly how you already do, just with a lot more context.
