Diff Checker
Compare two texts and highlight differences
Original Text
Modified Text
This tool compares two blocks of text side-by-side and highlights exactly what's been added, removed, or changed between them - useful for reviewing edits to a document, comparing two versions of code, or spotting the difference between two similar-looking pieces of text.
