Text Compare: Find the Difference Between Two Texts by Line, Word or Character

Paste the original on the left and the new text on the right. Differences appear at once: green is added, red is removed, and each line also carries a + or − so colour is not the only cue.

FAQ

Can it compare Thai text?

Yes. Line mode compares whole lines. Word mode splits on Thai letters and spaces; Thai has no spaces, so word mode can group long runs. Use character mode for fine detail.

Which algorithm is used?

Myers diff, the one git uses, which finds the shortest set of changes.
