Quick take
Suno turns a written prompt into a complete song, including vocals. Paid Pro and Premier plans currently get Suno v5.5; the Free plan uses v4.5-all. It is fast for background music and demos, but control can vary between generations and the copyright status of AI music is still unsettled.
Best fit
Suno is the right pick when you need original audio fast and mostly for your own content, such as videos, ads, or podcasts. It is less suited to projects where a track must be legally airtight or match an exact brief a client already signed off on.
