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.
