Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier in its niche. The only one that actually gets emotion right.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
