Kai's verdictB-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.S-tier for speed. When latency is the product, start here.A-tier. No reason not to use it if you're on Figma. Not worth switching for.
