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.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.
