Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for local inference. If you care about privacy or want to tinker, install this today.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.
