Kai's verdictA-tier for real-time. B-tier for everything else. Worth checking when news breaks.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-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.
