Compare Docs

Finding the changes is half the job. Knowing which ones matter is the other half.

Draft RFPs become finals. Proposals pass through five hands before submission. Amendments arrive with change logs that may not be complete. A report listing 700 changes still leaves you to find the three that move your bid.

Compare Docs handles both jobs, in two layers.

Layer 1: Detection

Every change, exactly

Pattern matching, not AI, finds every addition, deletion and modification. The same two files always give the same report.

Layer 2: Understanding

What it means, in plain terms

Visi reads the comparison, answers your questions and cites the source. You see the shift in meaning, not just the words.

Two versions, side by side

Original on the left, revised on the right. Every change is highlighted in place, so you read it in context instead of hunting for it.

Ask Visi about any comparison

Visi now works inside Compare Docs, on the comparison you have open. There's no switching tabs or pasting into a separate chat.

Start from a summary and suggested questions, or ask your own. Visi catches what highlighting can't show you: a deadline that moved, a "may" that became "shall", or a change that conflicts with another section.

1Answers you can check. Every answer cites the source.
2No guessing. If the documents don't hold the answer, Visi says so.
3You stay in control. Administrators can turn Visi on or off.

Compare at every stage of the proposal lifecycle

Documents change before you bid, while you write, and after you win. Compare Docs and Visi work the same way at every stage.

Capture and bid decision

Compare a draft RFP to the final, or a sources sought notice to the solicitation. Catch new requirements before your bid or no-bid call.

Ask Visi: "What changed between draft and final that affects our solution?"
Proposal development

Compare each amendment as it lands, and your drafts through each color team review. Confirm review comments made it in.

Ask Visi: "Which differences still need a review decision?"
Contract and post-award

Compare contract revisions, modifications and pricing workbooks. See what the other side changed before you sign.

Ask Visi: "Summarize what changed in this modification."

One comparison engine. Every stage of the lifecycle.

Inbound or outbound, the check is the same

What comes in

Compare draft to final, and each amendment. Catch a new product service code or a shifted requirement before it shapes your solution.

Trust, but verify. In both directions.

Works on Word, PDF and Excel

Compare Word and PDF documents, or one Excel workbook against another for pricing and delivery teams. Bid and contract teams get the same comparison.

Review, flag, and act on every change

Spotting a change is only the start. Flag it as a high concern, note why it matters, and route it to the right person.

Every flagged change is tracked, so nothing gets spotted and then forgotten.

Connected to the full workflow

Compare Docs sits alongside the shred, compliance matrix, outline, writing and watchword checks. Visi works across all of them, under the same permissions and audit trail.

In sensitive bids, knowing what changed isn't enough. You need to prove you caught it, who reviewed it, and what you did about it.

Caught.
Understood.
On the record.
The result

Nothing slips between versions. Every change is caught, understood and accounted for.
