For people who work through an AI agent
Where should your AI agent keep its work?
Ask your AI to keep it in a hedwigai workbook. A workbook is the system of record your agent writes to. It keeps every version, cites every source, and checks every edit. Your agent can read it again tomorrow, and so can you.
Reading and writing workbooks is free. A new account starts with $1 of credit and no card.
Why does an agent need a system of record?
Your agent builds a lead list, a market report or a weekly tracker. The work then sits in a chat that scrolls away, or in a file that nobody checks again. A link to a hosted page shows the work once. It does not say where each number came from, or whether it is still true.
A workbook keeps the work where the next run can find it. Your agent reads it, edits it and writes it back through the hedwigai MCP server. Any agent you connect sees the same workbook, so work started in Claude can continue in ChatGPT or Cursor.
What a workbook keeps that a chat does not.
Every version is kept.
Each write by your agent is a new version, labelled with what changed. An earlier version can be brought back in one step.
Every source is cited and watched.
What a run cites is fingerprinted. When a source changes, the workbook says so instead of going quietly stale.
Every edit is checked.
A workbook can declare its columns, types, required cells and keys. An edit that breaks them is refused, with the cell and the rule it broke.
No edit is lost.
An edit made on an old version, or over someone else's change, is refused. It is never merged over the newer work.
What do you say to your agent?
- “Keep this in a hedwigai workbook.”
- Your agent writes what it made as version 1 of a new workbook. Writing it costs nothing.
- “Open my hedwigai lead tracker and add the five companies we found today.”
- It reads the workbook, edits it, and writes a new version. The old one is kept.
- “Save the sources this workbook cites to my drive.”
- Every web page the workbook cites is copied into your connected drive.
- “Share the workbook with a link.”
- You get a link that always opens the current version.
- “Go back to yesterday's version of the workbook.”
- The earlier version becomes the current one again, as a new version.
- “Ask the workbook to refresh the numbers from this week's filings.”
- This starts a research run that writes the next version. Runs are billed to your prepaid credit.
How do you connect it?
hedwigai is one MCP server, at https://mcp.hedwigai.com. Every client signs in through your browser the first time it uses it.
Claude (web or desktop)
- Open hedwigai in Claude’s connector directory and click Connect.
- A hedwigai page opens. Sign in or create an account.
- In a chat, turn hedwigai on from the + menu.
ChatGPT
- In ChatGPT’s plugins, click Add, then Add custom MCP server.
- Name it hedwigai and give it the address https://mcp.hedwigai.com. Tick “I understand and want to continue”, then click Create as a plugin.
- A hedwigai page opens. Sign in, then pick hedwigai from the + menu in a chat.
Cursor
- Click Add to Cursor. Cursor opens with hedwigai filled in.
- Click Install, then Connect beside hedwigai.
- A hedwigai page opens in your browser. Sign in.
Claude Code, Codex and any other MCP client
- Say to your agent: “Set up hedwigai from https://mcp.hedwigai.com/llms.txt”.
- The agent reads the setup page, adds the server and tells you the one step left.
- That step is a sign-in in your browser. No token is pasted anywhere.
Are you an agent reading this?
Read /llms.txt. It says when to use hedwigai, how to connect the MCP server from any client, and what each tool does. Start with list_workbooks. Write what you made with create_workbook or write_workbook, which cost nothing. Ask before you start a run, because runs are billed to the person’s account.
