About Text Compare
This tool performs a line-by-line diff between two text blocks — highlighting lines that were added (green), removed (red), or changed (orange). Changed lines also show word-level inline differences so you can pinpoint exactly what was edited. All processing happens in your browser — nothing is sent to a server.
