Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for model-shopping. I use this for every prototype before committing.A-tier if you already pay Gemini. B-tier standalone.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.
