Question 1

Is text comparison safe?

Accepted Answer

Safe. The comparison of the two texts is done locally in your browser, and the content is never uploaded to any server.

Question 2

How are the differences calculated?

Accepted Answer

The tool uses the Longest Common Subsequence (LCS) algorithm for line-by-line comparison, finding the minimum number of additions and deletions between the two texts: green indicates added lines, red indicates removed lines, and the rest are unchanged lines.

Question 3

Can I compare code or configuration files?

Accepted Answer

Yes. Paste the two versions into the left and right columns to view differences line by line, suitable for comparing code changes, configuration files, document revisions, etc. Comparison is done on a line basis; minor differences within a line will mark the entire line.
