Kai's verdictA-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.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
