Writers track revisions. Developers check code changes. Editors verify accuracy. Comparing two versions of text comes up more often than you would expect. Our Text Compare Tool does this instantly, line by line, right in your browser.
Paste your original text on the left and your modified version on the right. Click compare. The tool highlights every line that differs. Matching lines appear normally. Changed lines get color coded with a pink background in the original and a blue background in the modified version. You also get a match percentage at the top that tells you how much of the text is the same.
This is useful for checking edits in a document, verifying that a transcription matches the source audio, or comparing two versions of code to find what changed. The diff output is read-only but you can copy either side to use elsewhere. The larger the match percentage, the closer the two texts are.
Common use cases include catching accidental deletions when editing blog posts, checking if someone changed terms in a contract, or quickly verifying that two config files are identical before deployment. The side-by-side layout makes it easy to spot exactly where text was added, removed, or modified without scanning through the whole document line by line.
All processing happens locally. Your text never leaves your browser.
