Text Difference Checker.
Compare two texts and highlight inserted, removed and unchanged words.
How to use Text Difference Checker
Paste the original and revised text, then compare.
How it works
Comparison preserves whitespace and highlights changes by word. It is useful for draft revisions, configuration edits or copied passages. A changed word appears as a removal and an addition; the tool does not infer the author’s intent.
Example
Hello world → Hello beautiful world highlights the inserted word.
