# Overview

ZeroWidth keeps the decisions your team makes, checks each one against your numbers, and shows your team and your AI agents what worked.

## Decisions from the tools your team already uses

Your team decides things in chats with Claude and ChatGPT, in coding sessions, in documents and in meetings. ZeroWidth keeps each decision with who made it, when, and what it was meant to change.

Decisions come in two ways:

- **Reported as they happen.** Connect an AI tool over MCP, and the tool reports each decision once the person agrees to it.
- **Read from history.** Bring in exports of past chats, documents and code, and ZeroWidth finds the decisions already made. You see the cost before anything is read.

## Each decision checked against your numbers

Every decision gets an expectation: the number that should move, which way, and by when. Anything the conversation didn't say is filled in and marked, and you can change any part.

When the time is up, the number's move is compared with how much it usually swings. Only a move bigger than the ordinary swing counts. The verdict is Worked, Mixed, Didn't work, No clear change, Too early to call or Can't tell. [How ZeroWidth works](https://zerowidth.ai/how-it-works)

## Results for your team and your agents

- **Your AI agents, before they act.** Agents look up past decisions and their results over MCP.
- **Your team, in the ZeroWidth console.** Every decision, the part of the business it touched, and how it turned out.
- **An export at any time.** All of your decisions as one file, with or without the original text.
