Text Diff Checker
Paste two versions of text to see which lines were added, removed or kept.
Questions fréquentes
Does it compare word by word or line by line?
It compares line by line, showing which lines were added, removed or kept between the two versions. It doesn't highlight individual word changes within a line.
Does it care about whitespace differences?
Yes, a line that only differs by trailing spaces or indentation is treated as a changed line, since the comparison is exact, character for character.
Is my text sent anywhere?
No, this runs entirely in your browser, the comparison happens locally and nothing is sent to a server.
