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