Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
