How to Compare Text

Paste your original text in the left panel and the modified text in the right panel. The diff output below will show you exactly what changed — added lines are highlighted in green and removed lines in red.

This tool uses a standard LCS (Longest Common Subsequence) algorithm to compute the minimal diff between two texts. It's useful for comparing code changes, document revisions, or configuration files.
