Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for realtime. If latency matters more than voice catalog, start here.B-tier. Useful for first drafts. v0 is the better bet for shipping code.S-tier for designers. The only one that takes vectors seriously.
