Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for speed. When latency is the product, start here.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.
