How the text comparison tool works
Last updated 10 November 2026
Comparing versions by eye is slow and error-prone. This tool lists what changed.
How it works
- Lines found in both texts are marked unchanged.
- Lines only in the original are removed; lines only in the new text are added.
What it shows
Paste the original text on one side and the changed text on the other. The tool lists what stayed the same, what was removed from the original and what was added in the new version. It is a quick way to check a contract draft, an edited email or a copy of a page against the first version.
How the comparison works
The tool compares line by line. A line that appears in both texts is marked unchanged. A line only in the original is marked as removed and a line only in the new text is marked as added. If you change one word in a long line, the whole line shows as changed.
Tips for cleaner results
- Put each sentence or item on its own line before you compare.
- Remove extra spaces at the ends of lines, because they count as differences.
- Use the text cleaner to tidy both versions first.
- Compare small sections one at a time if the document is long.
Common uses
- Checking what changed between two drafts of an agreement
- Comparing two lists of names or items
- Finding edits in a policy or terms page
- Spotting copy and paste mistakes in forms
Good to know
The tool does not understand meaning. It sees lines of text. It also cannot tell if a change is important. A moved paragraph shows as a removal and an addition. For legal documents, the comparison is a helpful aid and never a replacement for reading the final version. Everything runs in your browser.
Things to watch
- Small changes inside a long line mark the whole line as changed.
- Spaces at line ends count as differences.
Everything runs in your browser. Your text never leaves your device.
