Trial checklist
Use a real task involving vocal removal or stem splitting—not a demo prompt. Verify whether browser-based separation materially reduces editing or setup time. Record output quality, time to a publishable result, and total plan usage. Pay particular attention to whether the free tier covers your typical use. Repeat the same task in at least one alternative before deciding.
