Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier. Category leader. Nothing else is close yet.
