Diff Results
Text Diff Checker helps developers, writers, and QA teams compare two versions of content quickly. Paste the original on the left and the updated version on the right to see line-by-line differences highlighted in red and green.
Use it for code reviews, documentation edits, contract drafts, log comparisons, or content QA. The side-by-side layout makes it easy to spot additions, removals, and unchanged lines without switching between tabs.
Everything runs locally in your browser to keep sensitive data private. No uploads, no tracking, just fast, clear comparison results.
