Kai's verdict	B-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.	A-tier if you already pay Gemini. B-tier standalone.	B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.
