Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
