About this tool
Compares two blocks of text and marks what was added, removed and left alone. You can diff line by line, which suits code and configuration, or word by word, which reads better for prose and copy review.
Options for ignoring case and trailing whitespace keep the noise down when the real change is buried under reformatting. A summary counts the changed lines so you can size the difference at a glance.
How to use it
- 1Paste the original text on the left and the new version on the right.
- 2Pick line or word granularity.
- 3Read the highlighted result and the change summary.
