FAQ

What diff algorithm does this tool use?

The tool uses a line-based diff algorithm that compares text line by line, highlighting additions and deletions similar to version control systems like Git.

Can I compare code files?

Yes, you can paste code from any programming language. The diff works on plain text, so it handles code, configuration files, and documents equally well.

Does it support word-level diff?
