Frequently asked questions
Does this compare word by word or line by line?+–
Line by line. This tool suits comparing paragraphs, configs, or text lists row by row, not catching a one- or two-letter change inside the same sentence.
What do the red and green colors mean?+–
A red line on the left only exists in the first text (removed). A green line on the right only exists in the second text (added).
Can it compare very long documents?+–
Yes. Since the comparison runs in your browser, documents with thousands of lines can slow down a lower-spec device.
Are both texts uploaded to a server?+–
No. The comparison runs entirely in your browser. Nothing leaves your device.
