Best for	Replacing Google for any question where you want a cited answer in seconds.	Developers. Non-developers who want to ship working code.	Students, researchers, anyone with a stack of PDFs or a topic to learn.	Developers who want an agent, not autocomplete. Large refactors, tests, docs.
Strengths	Sources every claim Fast, current answers Pro Search runs multi-step research Spaces for persistent context	Tab completion feels like mind-reading Composer for multi-file edits Runs Claude, GPT, Gemini — you pick	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
Weaknesses	Not a general chatbot Answers can be shallow on complex topics	Can feel overwhelming for non-coders Expensive at scale	Google-only Can be slow on large corpora	Terminal-based — learning curve Can't be used without Claude subscription
Kai's verdict	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	S-tier for coding. If you write code of any kind, this pays back the $20 in a day.	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.
