Kai's verdictS-tier for realtime. If latency matters more than voice catalog, start here.S-tier for designers. The only one that takes vectors seriously.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.
