Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for builders. The right primitives. What Kai is built on under the hood.A-tier. Great price/performance. Go here if ElevenLabs is too expensive.A-tier. Niche but beloved. If you've outgrown Notion, try this.
