Choose the right comparison
Use text diff for wording, JSON diff for structured data, and image diff for visual changes. PDF text comparison does not tell you whether the page layout changed.
Similar audio is not identity proof
Compare recordings, mixes and exports. Volume, silence and timing offset affect similarity scores. A score cannot establish speaker identity or copyright ownership.
