How to use this tool

Spot changes between two versions of a text, configuration or response. Results identify added, removed and unchanged lines so you can review what changed.

  1. Paste the original text into before.
  2. Paste the updated version into after.
  3. Run the comparison and review the changed lines.

Example to try

Before: color: blue size: small After: color: green size: small

Supported use and limits

Up to 50,000 characters per side. Spaces and line endings are significant. Very large differences may require comparing smaller sections. This is a line comparison, not a semantic code review.

Why are visually similar lines marked as changed?

Whitespace or line endings may differ even when the words look identical. Format both documents consistently if you want to focus on content changes.
