Trace AI: I Pointed a Camera at a Whiteboard. Notion Built the Entire System Design Doc.

This is a submission for the Notion MCP Challenge What I Built Every engineering team has the same graveyard: folders full of blurry whiteboard photos that were supposed to become documentation. They never do. The meeting ends, the momentum dies, and that brilliant architecture sketch slowly rots in someone's camera roll. Trace AI kills that problem dead.
