Text Diff Checker
Paste two versions of a text and see which lines differ. Lines that match are shown unchanged, lines only in the original are marked with a minus, and lines only in the modified version are marked with a plus — the same convention used by version control diffs.

What the Text Diff Checker does
The comparison is positional: line 1 is compared with line 1, line 2 with line 2, and so on. This makes edits easy to spot, but it also means inserting a line near the top shifts everything below it and marks the remainder as changed. For reviewing edits within paragraphs, that is usually still the fastest read.
How it works

- 1Paste the original text into the first box.
- 2Paste the modified version into the second.
- 3Each line is compared with the line at the same position in the other text.
- 4Identical lines are shown as-is; differing lines appear as a − original and a + replacement.
- 5Read down the output to see every change in order.
