Text Diff Checker
Paste the old text and the new text — see every line that was added, removed or changed, with the exact changed words highlighted.
Paste the two texts you want to compare, then press Compare.
How to use it
Paste the original text on the left.
Paste the new version on the right.
Press Compare. Removals show in red, additions in green, with changed words highlighted inside changed lines.
Spot the change before it costs you
Contracts get revised, essays get edited, code gets patched — and the question is always "what exactly changed?" Reading two versions side by side by eye is how differences get missed. This checker aligns the texts and marks every addition and removal, down to the word level inside changed lines, so a single altered number in a clause or a swapped word in a quote jumps out immediately. Writers use it to review edits, students to check paraphrasing, and anyone to verify that "just a small change" really was small.
