Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.
