Kai's verdictS-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.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.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.
