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 price/performance. A-tier for consumer use. If you build apps, this is the budget pick.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
