Everything you need to verify the numbers
From extraction to sign-off, Signed Off keeps every figure accurate, reviewable, and accountable.
Automatic number extraction
Every number is pulled automatically — figures in narrative text and values inside tables alike. No manual transcription, no copy-paste, no missed digits.
Review item by item
Work through extracted numbers one at a time, filtered by the criteria that matter to you — number type, document section, and more — so nothing slips through.
Coordinate in one place
Comment on individual numbers, propose edits, and run circle-ups with your team without leaving the application. Every discussion stays attached to the work.
