The product

From first edit to final sign-off.

01 Capture

Every meaningful change, recorded.

Provenance lives inside Excel and PowerPoint. Each version keeps the author, the reason, and the exact state of the file.

The Provenance task pane open beside a DCF model in Excel, listing three changed assumptions with their before and after values, ready to version up

02 Understand

See what moved, and what it moved.

The redline traces a changed driver through valuation, cash flow, and every output it touches.

A Provenance model comparison across versions 2 and 3 of a DCF: a written summary of what moved, a key values table showing implied value per share falling to $442.02 and the discount to market widening to -18.9%, before-and-after grids with the changed assumptions highlighted, and a changes rail listing every edit

03 Compare

Sign off change by change.

Base and current sit side by side with every changed assumption called out.

A Provenance review of a DCF model carrying 286 changes, with a written summary of the effect on the investment case, before and current spreadsheets side by side, a changes rail grouping the edits by driver with a suggest-a-new-value action on each, and an approve-review action in the header

Excel add-in

The record starts in the workbook.

Provenance sits beside the model. It flags what looks wrong, shows exactly what changed since the last version, and saves that version with the reason attached — without leaving Excel.

The Assistant

Ask the deal. Get the evidence.

Ask with the frontier model of your choice: GPT-6 Astra, Claude Opus 5.5, Grok 4.6, and Gemini 3.8 Flash, each grounded in your models, documents, and deal history. Every answer links back to the exact version it came from.

The Provenance Assistant asked to check a deal's PowerPoint against its sources: the answer names the one figure on slide 4 that disagrees with the data room, links each claim to the slide and the source file it came from, and the model picker is open showing the frontier models an answer can be run on
A citation opened inside an Assistant answer: the source spreadsheet rendered in place, zoomed to row 2 of the operating KPIs file, with the cell holding 512.4 outlined and marked as an exact match

Every figure cites the cell it came from.

Not a document name, not a page guess. Open any number in an answer and the source file opens with it, scrolled to the exact cell and marked as an exact match. The citation is resolved by rule, so the same question returns the same cell every time.

Security
