Text Diff Checker
Paste the original text on the left and the changed text on the right to see what was added, removed or kept, line by line, with line numbers. Choose to ignore case or extra spaces. Both texts stay on your device.

Paste two texts above to compare them.
Lines are compared with the Myers diff algorithm, which finds the fewest added and removed lines. A changed line shows as one removed line followed by one added line. Ignoring case or spaces only affects matching; the original text is always shown.
