Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.A-tier in its niche. The only one that actually gets emotion right.A-tier for designer-led sites. S-tier if animations matter.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
