| Kai's verdict | A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs. | 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. | S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement. |
