Kai's verdictA-tier in its niche. The only one that actually gets emotion right.B-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.S-tier for solo + free. The best free option, hands down.
