For Audit & Assurance / Risk
Cut model review time, with evidence you can put in a workpaper.
Big 4 audit · model risk management · internal audit · third-party model review
The one capability that lands you
Proof Coverage
Workbook-wide score: percent inputs bound, percent formulas signed.

Demo comingWhat changes for you
Three concrete shifts.
- 01
Proof Coverage gives you a defensible workpaper metric (% inputs bound, % formulas signed).
- 02
Verify Ledger detects tampering or reordering of the proof history — cryptographic, not heuristic.
- 03
Review Issues Tracker centralizes every flagged cell across the engagement.
Supporting capabilities
Other features this persona uses regularly.
Same product, same install. The 6 features below are the ones Audit & Assurance buyers tell us they reach for after the lead capability.
Verify Ledger
Recompute the workbook's hash chain; detect tampering or reordering of the proof history.
Verify All Vectors & Blocks
Bulk recompute every bound vector and signed block; flag drift in one pass.
Model Health Report
Workbook-wide diagnostics on one page: formula counts, complexity distribution (so you know which sheets are doing the heavy lifting), error breakdown, hardcoded-constant count, volatile-function flags, and risk indicators. The one-page health check you'd otherwise build by hand with COUNTIF and INDIRECT.
Review Issues Tracker
An issue tracker that lives inside the workbook — severity, status, tags, comments, and savable issue sets, all persisted alongside the model. Reads like a model-review version of Linear or Jira: filter by severity, mark Resolved, save a set as a review packet for the next reviewer. Import an issue set from another reviewer's file with conflict detection.
Audit Trail
Mark cells Verified, Questionable, or Erroneous. Status persists in a .mxaudit JSON sidecar that lives next to the workbook on disk and auto-saves on every change — send the file plus its sidecar to your auditor and they open the model exactly as you left it. Status changes also feed the Proof ledger; bulk edits that revoke verified status are recorded as SignatureRevoked records so the loss is auditable after the fact.
Risk HeatmapCtrl+Shift+R
Three view modes — three different analyst questions answered by the same source code: (1) RISK — formula complexity scored on a blue/yellow/red gradient with errors flagged. (2) STRUCTURE — every cell type plus formula-consistency arrows (copied vs distinct). (3) AUDIT — only problematic cells: distinct formulas in arrays, hardcoded plugs in formula areas, external references, volatile functions, errors. One-click toggle, all-sheets analysis, customizable color schemes, interactive legend panel.
