Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for academic research. Nothing else comes close for systematic reviews.A-tier. Best free agentic option in VS Code. Use with Claude for best results.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.
