- Option to ignore case differences
- Option to ignore whitespace

Common Use Cases
1. Code Review
Find subtle differences between code versions, especially useful for tracking small changes in variable names or syntax.
2. Data Verification
Compare data entries to ensure accuracy, particularly useful for checking copied text against the original.
3. Document Comparison
Compare different versions of documents to identify small changes or typos.
4. Quality Assurance
Verify text content matches specifications exactly, character by character.
Example Comparisons
Case Sensitivity Example:
With case-sensitive comparison, differences will be highlighted. With case-insensitive option, texts will match.
Whitespace Example:
With whitespace sensitivity, extra spaces will be highlighted. With whitespace ignored, texts will match.
Tips for Best Results
- Use case-insensitive comparison when checking for content rather than exact matches
- Enable whitespace ignoring when comparing texts from different sources
- Check the match percentage for a quick overview of similarity
- Review highlighted differences carefully to understand the exact nature of changes
- For long texts, consider comparing sections separately for better visibility
