Kai's verdictA-tier. Close second to Cursor. If $5/mo matters, start here.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.
