Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Niche but beloved. If you've outgrown Notion, try this.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.
