About Text Diff

Spotting what changed between two versions of a contract, article or code file by eye is slow and easy to get wrong. A diff tool highlights every change instantly.
Confileo's Text Diff tool compares two blocks of text — Arabic or English — and highlights every addition and deletion line by line, entirely in your browser with nothing sent to a server. Ideal for reviewing edits, tracking revisions and confirming versions.
