Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for designers. The only one that takes vectors seriously.S-tier for realtime. If latency matters more than voice catalog, start here.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
