Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier for model-shopping. I use this for every prototype before committing.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.
