Comparateur de textes en ligne

The Diff Checker compares two blocks of text and highlights exactly what changed: removed words are marked in the left pane, added words in the right pane, right down to the word level within an edited line. It is built for content editors, SEOs, and developers who need to review a revised page, an updated meta description, or a rewritten paragraph without re-reading the whole thing line by line.

Paste the original version on the left and the new version on the right — the comparison runs instantly in your browser, so nothing you paste is sent to a server, and there is no practical size limit on the text you can compare.
