It is built for the moment before you sign an amendment. Load the version you agreed to and the version you were just sent, review the differences side by side, and sign only once you know exactly what moved.
How it works
- Add the original contract PDF and the revised version you want to check.
- The tool extracts the selectable text from both files.
- Differences are highlighted so added, removed, and changed wording stands out.
- Read through the changes, paying close attention to amounts, dates, names, and deadlines.
- Once you understand every difference, sign the version you agree with — or send it back for another revision.
Your privacy
Both contracts are compared entirely in your browser — the files and their text never leave your device.
Nothing is uploaded to a FinSafe server, so two confidential agreements stay private on your machine.
Your documents are never used to train AI models.
Common use cases
- Check an amended loan agreement against the version you originally signed.
- Confirm a payment extension only changed the dates you agreed to move.
- Spot an altered interest rate or amount in a revised installment plan.
- Verify that a settlement agreement matches what was negotiated over chat.
- Catch clauses added or removed between drafts before committing to sign.
Limitations
- It compares text, not layout — reordered sections or reformatted pages may show up as differences even when the meaning is unchanged.
- Scanned or photographed contracts have no selectable text, so their words cannot be compared until they are run through OCR, which this tool does not yet do.
- The comparison shows what changed, not whether a change is fair or lawful — that judgment is yours.
- Password-protected files must be unlocked before comparing.
Frequently asked questions
How does the comparison work?
The tool reads the selectable text from each PDF and lines the two versions up, marking where words were added, removed, or changed. You see the differences rather than having to hunt for them by eye.
Can it compare scanned contracts?
Only if the scan contains real, selectable text. A photo or scan that is just an image has no text layer to read, and this tool does not yet perform OCR, so convert or retype those pages first.
Will formatting changes show as differences?
They can. Because the comparison is based on text, moving a paragraph or changing layout may appear as a change even when the wording is identical. Focus on differences in amounts, dates, and names.
Are my contracts uploaded to compare them?
No. Both files are read and compared in your browser on your own device. Neither document is sent to a server.
What should I look at most carefully?
The numbers and names: loan amounts, interest, due dates, penalty terms, and the parties. These are the details most often changed between versions, and the ones that matter most when you sign.
Does the tool tell me if a change is unfair?
No. It shows you what is different; deciding whether a change is acceptable is up to you, and for significant contracts it is worth asking a professional before you re-sign.
