AI review

A second set of eyes.

Vowl reads every change and flags what matters — broken references, assumption drift, deviations from your team's standards. Configure rules in plain English and get a review on every change, automatically.

Lives where your team already works.

Use the Vowl plugin to pull the latest version of any file, propose updates, and review change history. All without leaving Excel.

  • Inline diffs without leaving your workbook

The control layer for AI-assisted work.

AI is changing how models get built, how memos get drafted, and how analysis gets done. But finance teams still need to know what changed, why it changed, and whether it's right.

Flag mistakes before they reach the deck.

Catch broken references, assumption drift, and deviations from your team's standards on every change.

Summarize what's new.

Get a plain-English breakdown of every update, so reviewers know what to look at first.

Stay on top of your team.
