Best for	Students, researchers, anyone with a stack of PDFs or a topic to learn.	Developers who want an agent, not autocomplete. Large refactors, tests, docs.	Teams with GitHub already. Devs who don't want to change IDEs.	Long writing, code, careful thinking, documents over 50 pages.
Strengths	Upload anything, ask questions, get cited answers Audio Overview turns docs into a 10-min podcast Great for studying	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	Best-in-class writing + nuanced reasoning 1M context on Opus Artifacts for code/docs Lowest hallucination rate in my testing
Weaknesses	Google-only Can be slow on large corpora	Terminal-based — learning curve Can't be used without Claude subscription	Less agentic than Cursor/Claude Code Model quality varies	Image generation is weak No native web search on all tiers
Kai's verdict	S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.	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.	S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
