Frequently Asked Questions
- What types of differences does it detect?
- The tool highlights line-by-line additions (new text), deletions (removed text), and unchanged content between the two inputs.
- Can I ignore case differences?
- Yes. Toggle the case-insensitive option to treat uppercase and lowercase letters as equal.
- Can I ignore whitespace differences?
- Yes. Enable the whitespace-ignore option to focus on meaningful content changes only.
- Is there a character or length limit?
- There is no hard limit. Very large texts may take a moment to process, but there is no capped length.
- Is my text sent to a server?
- No. All comparison runs locally in your browser. Your text is never transmitted anywhere.
