About the Text Diff Checker

Use the Text Diff Checker to compare two blocks of text and see added, removed, and unchanged lines. It is helpful for snippets, config changes, copy edits, generated output, and quick before-and-after checks.

Common uses

  • Compare two versions of copy or notes.
  • Check small config or code snippets before sharing.
  • Ignore whitespace or case when those differences do not matter.
  • Copy a unified-style diff summary for issues or docs.

Browser workflow

  1. 01 Paste the original text and modified text.
  2. 02 Toggle whitespace or case normalization if needed.
  3. 03 Review additions, removals, and unchanged line counts.
