Frequently Asked Questions

Find Quick Answers

What types of text can I compare with this tool?

You can compare any plain text content including documents, code snippets, essays, articles, emails, or any textual data. The tool works with all languages and character sets.

How does the text comparison algorithm work?

The tool uses a sophisticated diff algorithm that compares character sequences to identify additions, deletions, and modifications. You can choose between different comparison modes to suit your needs.

Is my text data secure when using this tool?

Yes, all text comparison happens entirely in your browser. No data is sent to any server, ensuring complete privacy and security for your content.

Can I compare very large texts?

Yes, the tool can handle large texts, but extremely large documents (over 100,000 characters) may slow down the browser. For best performance, we recommend comparing texts under 50,000 characters.

What do the different comparison options mean?

Case-sensitive: Treats uppercase and lowercase letters as different. Ignore whitespace: Removes spaces, tabs, and line breaks before comparison. Line-by-line: Compares text line by line instead of character by character.
