Best for	Replacing Google for any question where you want a cited answer in seconds.	Long writing, code, careful thinking, documents over 50 pages.	Developers who want an agent, not autocomplete. Large refactors, tests, docs.	Anyone already on Google, research tasks, summarizing long documents.
Strengths	Sources every claim Fast, current answers Pro Search runs multi-step research Spaces for persistent context	Best-in-class writing + nuanced reasoning 1M context on Opus Artifacts for code/docs Lowest hallucination rate in my testing	Runs locally, edits your actual files Strong on large codebases with 1M context Great at multi-step tasks	Native Google Workspace integration Very long context (1M+) Deep Research feature Free tier is generous
Weaknesses	Not a general chatbot Answers can be shallow on complex topics	Image generation is weak No native web search on all tiers	Terminal-based — learning curve Can't be used without Claude subscription	Writing quality trails Claude Over-refusals on edge content UI is cluttered
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 reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
