Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.
