| Kai's verdict | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic. | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. | S-tier for local inference. If you care about privacy or want to tinker, install this today. |
