Frequently Asked Questions

How is similarity percentage calculated?

Similarity is calculated based on the number of matching lines divided by the total number of lines in both texts.

Can I compare large files?

Yes, but for very large files (10,000+ lines), the comparison may take a few seconds. All processing happens in your browser.

Is my text stored anywhere?

No. All comparison happens entirely in your browser. Your text never leaves your device.
