Kai's verdictA-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.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.
