Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
