Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.A-tier if you already pay Gemini. B-tier standalone.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier in its niche. The only one that actually gets emotion right.
