Compare Contract Versions & Detect Changes
Instantly
Spot hidden changes, stealth edits, additions, and deletions in seconds. Never miss a contract amendment or clause modification again. Perfect for NDAs, service agreements, employment contracts, and legal amendments.
Prevent Stealth Edits & Hidden Contract Changes
Manually comparing contracts line-by-line is error-prone, time-consuming, and dangerous. Legal teams and procurement professionals lose hours reviewing redlines.
Missed Contract Changes & Amendments
Counterparties often slip in 'minor' tweaks that drastically change liability, payment terms, or renewal dates. Our contract diff tool catches every modification.
Wasted Hours on Manual Review
Staring at two documents side-by-side for hours kills productivity and leads to fatigue errors. Compare contracts instantly with AI redlining instead of manual comparison.

Frequently Asked Questions
Everything you need to know about our AI contract comparison and redlining tool
How does this contract comparison tool differ from Microsoft Track Changes?
Track Changes only works if enabled beforehand and is limited to Word documents. Our AI contract comparison tool compares *any* two text versions, even if they're from different file formats (e.g., PDF vs Word, Google Docs vs PDF). Perfect for comparing legal amendments from any source.
Can it detect hidden deletions and stealth edits?
Yes. Our contract diff tool highlights every single deletion, addition, clause modification, and stealth edit, so nothing slips through. You'll see exactly what changed between versions with our similarity scoring.
Is my confidential contract data secure and private?
Yes. We process your legal documents in real-time memory for comparison and then immediately discard them. We do not store, log, or retain your confidential contracts. Your data privacy is guaranteed with zero storage.
Does it work with PDFs, Word docs, and other file formats?
Yes, you can upload PDF, DOCX, DOC, or plain text files. The contract comparison tool extracts text and compares it regardless of format, making it perfect for comparing amended contracts across different platforms.
What is the "Similarity Score" and what does it mean?
It's a percentage indicating how closely the two contract versions match. A lower similarity score means more significant changes, additions, deletions, and clause modifications were made between the original and revised versions.
What types of contracts and amendments can I compare?
You can compare any legal document including NDAs, service agreements, employment contracts, vendor agreements, lease agreements, purchase orders, partnership agreements, and any contract amendments or redlines.
How fast is the contract comparison process?
Most contract comparisons are completed in seconds, regardless of document length. Our AI instantly identifies all changes, additions, deletions, and clause modifications to provide instant redlining analysis.
