FAQ

How does the comparison work?

The tool compares texts line by line. Lines present only in the first text are marked with (-), lines only in the second with (+), and matching lines are unmarked.

Does it ignore whitespace?

Currently, whitespace is considered in comparisons. Trailing spaces and different indentation will show as differences.

Can I compare code files?

Yes! This tool works well for comparing code snippets, configuration files, or any text-based content.
