Kai's verdictA-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier inside Photoshop (Generative Fill). B-tier standalone.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.
