Frequently Asked Questions

Find Quick Answers

What types of differences can this tool detect?

The tool detects additions (text present in the second but not first), deletions (text present in the first but not second), and changes (modified text between versions).

Can I compare large documents with this tool?

Yes, the tool can handle substantial text inputs, though extremely large documents (over 100,000 characters) may experience slower processing.

Does the tool save or store my text?

No, all processing happens entirely in your browser. Your text is never sent to any server or stored anywhere.

What's the difference between character, word, and line comparison modes?

Character mode compares individual characters, word mode compares whole words, and line mode compares entire lines. Word mode is usually best for document comparison.
