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

Using the Text Diff Checker

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