Compare Legal Contract Versions — See Every Change
Paste two versions of a contract and instantly see every insertion, deletion, and modification highlighted at the character level. Never miss a hidden change.
When the other side sends back a "lightly revised" contract, you need to know exactly what changed. Did they modify the indemnification clause? Add a non-compete? Change a payment term from 30 to 60 days? Reading both versions side by side is slow and error-prone. A text diff tool catches everything — instantly.
Paste the original and revised contract text into this tool and see every change highlighted at the character level. Added text appears in green. Removed text appears in red. Nothing is missed, even single-word changes buried in dense legal language.
Features
Word and Line Precision
Use word-level review for subtle contract language and line mode for broader section changes.

Changes are highlighted the moment you paste both versions. No waiting, no processing delay.
How It Works
Copy the original contract text and paste it into the left panel.
Copy the revised contract text and paste it into the right panel.
Every addition (green), deletion (red), and modification is highlighted for quick review.
Why Text Diffing Is Essential for Contract Review
In legal practice, a single changed word can alter the meaning of an entire clause. "Shall" becomes "may." "Exclusive" becomes "non-exclusive." "30 days" becomes "60 days." These changes are easy to miss when scanning a multi-page document, especially under time pressure.
Word's Track Changes feature is the traditional solution, but it depends on the other party actually using it — and using it honestly. When you receive a clean document described as "minor revisions," the only reliable way to verify what changed is a text-by-text comparison.
This tool provides that comparison without requiring any software beyond a web browser. It is faster than reading both versions side by side, more reliable than depending on the other party's track changes, and completely private — your contract text never leaves your browser.
