How does semantic JSON comparison differ from a text diff?
Diff Anything parses JSON before comparing it, so formatting and property order do not create meaningless line changes. Pro profiles can retain ignored paths, keyed or unordered array behavior, case rules, numeric tolerances, review state, and report settings.

Do compared files leave the computer?
No. Comparison is local. The application has no account, cloud comparison service, analytics, or telemetry.
How does automatic mode choose a comparison?
Matching structured formats use their semantic engine, two folders use folder comparison, and other compatible inputs fall back to text. You can always choose a concrete mode.
