This tool breaks both texts into words (or lines) and finds the longest sequence of matching pieces shared between them. Anything in the original text that doesn't appear in that shared sequence is marked as removed, and anything new in the changed text is marked as added — the same basic approach used by version control tools like Git.
Use "Ignore case" when capitalization differences don't matter to you, and "Ignore extra whitespace" when you only care about actual wording changes rather than spacing or formatting.

Add your original text on the left and the updated version on the right.
Pick word or line comparison, and toggle case or whitespace sensitivity.
See every change highlighted instantly, along with a summary of additions and removals.
