Kai's verdictS-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.S-tier. If you're on Vercel/shadcn, this is cheating.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Best free agentic option in VS Code. Use with Claude for best results.
