Context is king.

A document is only as good as what it was written from. So a workbook goes to the primary sources that matter to you: SEC filings, FDA labels, clinical trial registries, customs records, procurement awards.

And to the files you already keep. Connect Google Drive, Dropbox, OneDrive or SharePoint, and it works from what is there.

If a source you need is missing, we add that data hose. That is our enterprise work: talk to us.

Every line cites the page or row it came from.

How it works.

  1. 01

    Describe it. One sentence saying what the document is.

  2. 02

    It does the work. It reads the primary sources and your own files, and cites each one.

  3. 03

    Several AI models share it. Each takes the part it does best: gathering, writing, checking.

  4. 04

    It updates itself. When a source changes, the workbook changes with it and tells you what moved.

  5. 05

    You change it with a sentence. Ask in plain English and it rewrites the part you meant.

Give your agent the data MCP.

Connect the hedwigai MCP and your agent can ask, list, start and change workbooks. You speak in sentences; it makes the calls.

A short answer from your workbooks and programs, with the source it rests on. Nothing to wait for.

Your agent

What you can build.

A workbook is one document with one job. You don't maintain it; it arrives researched and finished, and it keeps itself up to date.

Lead reports

Who to sell to, and why now. Customs records, procurement awards and project wins, qualified against your own criteria, with an outreach email drafted for each.

US importers of heavy engineering equipment.

Diligence documents

The pack on a company, a target or a supplier. Filings, labels, trial results and investor decks, gathered and checked, with every claim linked to its source.

Diligence on eleven biotech companies.

Spreadsheets

Trackers, budgets and models. Change an assumption in plain English; the numbers move and it tells you which ones did.

The client list nobody has updated since March.

Built to be checked.

Sources on every claim

Each line traces to the filing, page or row it came from.

Every update says what changed

When a source moves, you see which lines changed and which source moved them.

Shared with your team

Invite the people you work with, and they can read the workbook and ask for changes too.

You are asked only when it matters

It stops for a decision or an approval, and otherwise gets on with the work.

We publish what it got wrong.

Each test takes one real task and checks the result against a list written before it began. The numbers stay up, misses included.
