Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.S-tier if you're on Mac. The fastest way to get AI answers without context-switching.A-tier. Niche but beloved. If you've outgrown Notion, try this.
