Frequently asked questions
How does the diff algorithm work?
We use a longest-common-subsequence (LCS) approach over lines, the same idea behind Unix 'diff'. Each line is compared as a whole.
Can I see word-level differences?
Currently we diff per line. For word-level granularity, paste shorter snippets so each sentence becomes its own line.
Are the original texts uploaded?
No. The whole comparison runs in your browser; nothing is sent anywhere.
