| Kai's verdict | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs. | A-tier. Best free agentic option in VS Code. Use with Claude for best results. | A-tier for social/casual. B-tier for serious work. Good entry point. |
