Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-tier for model-shopping. I use this for every prototype before committing.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
