Helpful Information

How text comparison works

The tool compares your two texts line by line. Lines that exist only in the second text are shown as additions (green), lines only in the first text are shown as removals (red), and unchanged lines appear in neutral color.

Limitations

This tool performs line-level comparison. Word-level or character-level highlighting within lines is not yet supported. For code comparison, consider using a dedicated code diff tool for syntax highlighting.
