Frequently asked questions
Is my text uploaded?
No. Everything runs inside your browser. Your files and text never leave your device and nothing is stored on our servers.
Does it compare words or lines?
It compares line by line using a longest-common-subsequence diff, the same approach as git.
Is there a size limit?
Very large texts (thousands of lines on both sides) may be too heavy for the browser; the tool will warn you.
