Kai's verdictA-tier. Best free agentic option in VS Code. Use with Claude for best results.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier. Category-defining UX. If you take notes in meetings, switch this week.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
