| Kai's verdict | B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic. | A-tier. The most interesting spreadsheet in years. Great for ops dashboards. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. |
