Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for speed. When latency is the product, start here.S-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.
