How to use Text Difference Checker

  1. Paste the original text into the first field.
  2. Paste the revised text into the second field.
  3. Run the comparison and review the marked differences.
  4. Align paragraph breaks in both inputs first if too many lines appear changed.
Practical example

Compare two policy drafts to spot changed paragraphs before review.

Check your result before using it

Compare a sample with a changed word, an added line and a whitespace-only edit so you understand the highlighting. Then inspect the surrounding paragraphs instead of accepting every highlighted change as meaningful. A textual difference does not establish whether two statements have the same meaning. For contracts, code or structured records, review the actual changes in context and retain both source versions for reference.

When to use Text Difference Checker

  • Compare two policy drafts to find changed paragraphs
  • Check what changed between two versions of a short document
  • Review edits made to a piece of copy before approving it

Important limitations

  • This is a positional line comparison rather than a semantic or word-level diff.
  • Inserted lines can make later unchanged lines appear shifted.

Troubleshooting Text Difference Checker

Too many lines appear changed

Align related paragraphs and line breaks in both inputs before comparing again.
