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.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.A-tier for designer-led sites. S-tier if animations matter.
