Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.
