Text Diff Questions

It finds the longest common sequences between two texts, then highlights what's added, removed, or changed. Same algorithm Git uses under the hood.

Green = added (in new, not in old). Red = deleted (in old, not in new). Unchanged stays plain. Character-level changes get highlighted within lines.

Works for anything text-based - code, configs, markdown, SQL, whatever. Paste two versions of a file and see every addition and deletion highlighted line-by-line and character-by-character.
