Kai's verdictA-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Niche but beloved. If you've outgrown Notion, try this.
