Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for local inference. If you care about privacy or want to tinker, install this today.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.
