# ZeroWidth

> Your team's decisions are already written down in their conversations with AI. ZeroWidth connects each decision to the metric it was meant to move, and shows which ones worked.

ZeroWidth is free to run yourself today, from a copy of the ZeroWidth repository with Node 24 or later. Hosted ZeroWidth is in development. Agents connect over MCP.
