Compare Docs
Compare any two document versions and see every change, down to the word, with no guessing and no missed edits.
Book a demo
15+ years in sensitive, high-stakes bids. Now with AI doing the jobs AI is actually good at.
A draft RFP becomes a final. Your own proposal goes through five hands before submission. The government issues an amendment with a change log that may or may not be complete. Every one of those moments is a chance to miss something that matters.
Compare Docs catches what changed, exactly, every time. It's pattern matching, not AI, so the report is 100% accurate and identical every time you run it. No prediction. No variance. No "let me run it again to be sure."
Two versions, side by side
Original on the left, final on the right. Modifications, additions, and deletions all highlighted in place, so you read the change in context instead of hunting for it.
Inbound or outbound, the check is the same
Run it on draft solicitation against final, so you catch a new product service code or a shifted requirement before it shapes your solution wrong.
Run it on your own proposal versions, to verify the cyber section actually got updated and the change you asked for actually made it in. Especially when multiple authors write different sections.
Trust, but verify. In both directions.
Works on Word, PDF, and Excel
Compare documents in Word or PDF. Compare one workbook against another in Excel, for the pricing and delivery teams who live in spreadsheets.
Review, flag, and act on every change
A change isn't just something to notice. It's something to act on. Mark a change as a high concern, add a comment on why it matters, and route it to the people who need to handle it.
Every flagged change becomes a tracked reference point, so nothing gets spotted and then quietly forgotten.
Connected to the full workflow
Compare Docs doesn't live in isolation. The shred, the compliance matrix, the outline, the writing, the readability and watchword checks are all part of the same environment, governed by the same workspace permissions, backed by the same audit trail.
In sensitive bids, you don't just need to know what changed. You need to prove you caught it, who reviewed it, and what you did about it.
Reviewed.
On the record.
Nothing slips between versions. Every change caught, reviewed, and accounted for.
