Comparison runs locally in your browser. Interactive diff uses a bounded token count to avoid locking the page on extremely large inputs.

Repeated whitespace, tabs and line breaks collapse for matching, while the review still reports whether the raw text differs so meaningful formatting changes are not hidden.
