What a cover means here
A traditional cover is another artist performing a song. The AI version works from your recording: you upload audio, the model reads its melody and structure, and it generates a fresh performance in the style you describe. Think of it as handing a demo to a band you have never met and asking them to play it as folk, as synth-pop, or as a stripped-back piano ballad.
Because the source is your upload rather than a catalogue entry, the page is most useful for your own material. Singer-songwriters use it to hear a voice memo with full production, and producers use it to audition genres before committing to an arrangement.
