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.S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
