About Diff Checker

A diff checker is a tool that compares text to find and highlight the differences between two versions of the same content. It's useful for:

  • Comparing code changes between different versions
  • Reviewing document edits and revisions
  • Finding discrepancies between similar texts
  • Identifying changes in configuration files
  • Checking for plagiarism or content duplication

How to Use

  1. Paste your original text in the first textarea
  2. Paste the modified version in the second textarea
  3. Select your comparison options (case sensitivity, whitespace)
  4. Choose your preferred view mode (side-by-side or inline)
  5. Click "Compare" to see the differences highlighted

Note: This diff checker operates line by line. Each line is treated as a separate unit for comparison. For large texts, the comparison might take a moment to complete.
