FAQ
Are my text inputs uploaded?
No. Text comparison runs in your browser using JavaScript. Your text never leaves your device.

Yes. The tool compares any text content including code snippets, configuration files, and documentation.
What happens if I ignore whitespace?
The comparison treats multiple spaces as one and ignores leading/trailing whitespace, useful for formatted text.
