How this tool works
Paste the original and updated text, then compare. Green + lines were added and red − lines were removed; unchanged lines keep their original order. Comparison is line-based, with a maximum of 1,000 lines and 100,000 characters per version. Use Swap versions to reverse the comparison. Optionally ignore letter case or leading/trailing whitespace. Line endings are normalized. A trailing newline is treated as an empty final line.
Does the comparison work line by line or word by word?
Lines are matched first, then differences within a changed line are highlighted, so you can see a single altered word without the whole paragraph turning red. Reflowed paragraphs still show as fully changed — that is a real difference in the text.
Can I compare two Word or PDF documents?
Paste the text rather than the file. Formatting, tracked changes and images are not compared — only the characters — which is usually what you want when checking wording in a contract.
Is my text uploaded anywhere?
No. The comparison runs in your browser, so drafts, contracts and source code never leave the machine. Nothing is stored once you close the page.
