Picard is not automatic, I'd describe it mostly as "assisted".
There's a two step process of track clustering and release metadata searching that are automatic, but each transition to the next step is manual so that you can review and adjust (either by using another matching method, fixing the lookup by pointing it to the correct release, or manually editing).
There's a "gold disc" visual feedback for when it detected perfect matches.
You can also decide if some/all tags should be updated from the global database or kept from the original file thus using the database as enrichment.
