Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.A-tier if you already pay Gemini. B-tier standalone.S-tier for model-shopping. I use this for every prototype before committing.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
