Strengths	Upload anything, ask questions, get cited answers Audio Overview turns docs into a 10-min podcast Great for studying	Free extension for VS Code Plan + Act modes Model-agnostic (Claude, GPT, local) Sees terminal output and iterates	Runs locally, edits your actual files Strong on large codebases with 1M context Great at multi-step tasks	Great enterprise story Works in your existing IDE Chat + autocomplete
Weaknesses	Google-only Can be slow on large corpora	Can burn tokens fast if not watched Less polished than Cursor	Terminal-based — learning curve Can't be used without Claude subscription	Less agentic than Cursor/Claude Code Model quality varies
Kai's verdict	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.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
