INTAKE — DOCUMENT OPENED

Every number, checked.

Flag opens your workbook, extracts every line, and cross-checks every claim against source. One broken value is enough to lose trust. We catch it before your first meeting.

Parse — Every Value Typed

A financial document is never a list of numbers. It is a graph of claims.

Flag extracts every value from the deck, the workbook, and the board pack, tags it with unit, currency, period, and source, and wires it into a single canonical graph. This is the step LLMs cannot do reliably — determinism requires structure, not paraphrase.

Spotting one wrong number takes a second. Guaranteeing no wrong number exists is a different job — and humans, however senior, were never designed for it.

The Catch — value lift

Watch the value leave the sheet, enter the audit graph, and return as verified truth.

A real balance-sheet value is lifted from Sheet2!B30, processed through deterministic checks, collides against a conflicting sum, expands into a flag card, and heals back into the workbook with a reproducible fix.

Establishing Sheet2!B30 — scan in progress.

Determinism — Same Prompt · Two Worlds

Ask a language model. Ask Flag. Only one returns the same answer twice.

The same document. The same question: 'find every place the numbers don't agree.' An LLM writes a confident paragraph. Flag returns a deterministic, reproducible trace — with the rule it applied and the exact cell it came from.

POINT

LLMs are brilliant writers. Finance is not a writing problem. It is a reconciliation problem — and reconciliation demands determinism.

FLAG · 2026

Verified — Document Cleared

Zero unresolved. Three fixed. One audit, sealed.

Every finding was traced, resolved, and reconciled against source. The document leaves your hands with a reproducible audit trail attached — something no LLM can produce, and no spreadsheet has ever had.
