Frequently asked questions
How do I compare two texts online?
Paste the original text on the left and the changed version on the right, then click Compare. Added and removed lines are highlighted.
Does this compare word-by-word or line-by-line?
Line-by-line — it's best suited for comparing config files, code, or paragraphs where whole-line changes matter most.
