Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.A-tier. Niche but beloved. If you've outgrown Notion, try this.
