How it works

One model.Every document in step.

Excel calculates. MIDMEN keeps the official numbers and where each one came from. Your reports and decks stay wired to them.

  1. ConnectTell MIDMEN which cells are the official numbers
  2. PublishA version of them, each with its cell and source
  3. Documents updateEvery figure in Word and PowerPoint refreshes
  4. A sentence turns redIts rule no longer holds on the new numbers
  5. FixNew words around the same live numbers
  6. ApproveA person signs off the tracked change

Every versionis kept.

Publish records each number, its cell, its formula and when. A one-line note says what changed; MIDMEN suggests it for you.

New period columns or moved rows? Publish notices them and offers to add them, so a forecast that grows by a year keeps its documents.

Version 214 Oct
Segment A volume 1,28,000 to 1,12,500: revenue ₹1,242 Cr to ₹1,180 Cr.
Version 112 Oct
First version of the Acme model.
Publish found something new

A new period, FY27, on 4 rows that feed published numbers.

Sentencescarry rules.

Each checked sentence says when it is true, in plain words. When new numbers break the rule, the sentence turns red.

Change a rule from the pane with Edit rule. MIDMEN shows the result on the current version before it saves.

Quarterly update.docx
Revenue grew 4.0% quarter on quarter to ₹1,180 Cr.No longer true
Edit rule

True when revenue growth, this quarter, is above 0.

On version 2: revenue growth is −4.0%, so this sentence turns red.

Fix,then Approve.

Fix proposes new words while the numbers stay wired. In Word it arrives as a tracked change; in PowerPoint as Before and After. A person approves.

Edited a sentence or a slide by hand? Keep my edit links its numbers again instead of overwriting your words.

Quarterly update.docxTracked change

Revenue grew fell 4.0% quarter on quarter to ₹1,180 Cr.

Waiting for your approval

Explain why,without guessing.

When a version moves a number, Excel reruns the model with each changed input put back and names the driver. No AI is involved.

From the launch video, 12 Oct 2026: Changes, then Explain why, in Excel.

Check any fileagainst the model.

Open a Word report or a deck MIDMEN did not make. It checks every figure against the published versions. Link them wires the matches without changing the page.

Matches₹1,180 Cr is revenue in version 2
Older version₹1,242 Cr was revenue in version 1; it is ₹1,180 Cr now
Close₹1,181 Cr is within 0.5% of a published number, but not as printed
Not found₹1,310 Cr is not a published number

Owner

Manages people, publish rules and the workspace's AI key

Editor

Publishes versions, fixes and approves sentences, stamps documents

Viewer

Sees numbers, documents, sources and changes; changes nothing
Publish rules
Simple or Reviewed, or your own switches. Claude follows the same rules as the pane.
"This is intended"
A number typed over a formula needs a reason before it is published. Source then shows a Remark: the formula's own value, the number used, the reason and who gave it.
A second OK
Optional: an editor's version waits until another owner or editor approves it. Documents keep the previous version until then.
Typed over on purpose
One list of every number typed over a formula, across versions, with its reason, and whether it is still typed over.

Valuation modelsas they are.

DCFs with actuals next to forecasts, LBO and project-finance models with intended circular references, comps tables, sensitivity grids and Monte Carlo runs publish without being rebuilt.

The AI neverwrites a number.

Excel is the only calculator. When AI drafts or fixes a sentence, it picks which published number goes where. A typed-in figure in a report is flagged.

Try it on the sample.
