Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
