	Claude Code S	Claude S	Perplexity S	Gemini A
Tagline	Anthropic's CLI agent. Opus-powered, operates on your repo directly.	Anthropic's flagship — best reasoning + longest useful context.	AI search done right. Cited answers, not chat theater.	Google's answer. Best integrated with Workspace + free for a lot.
Category	coding	chat	research	chat
Pricing	Part of Claude Pro/Max/Team plans	Free + $20/mo Pro + team/enterprise	Free + $20/mo Pro	Free + $20/mo Advanced (bundled with 2TB Drive)
Best for	Developers who want an agent, not autocomplete. Large refactors, tests, docs.	Long writing, code, careful thinking, documents over 50 pages.	Replacing Google for any question where you want a cited answer in seconds.	Anyone already on Google, research tasks, summarizing long documents.
Strengths	Runs locally, edits your actual files Strong on large codebases with 1M context Great at multi-step tasks	Best-in-class writing + nuanced reasoning 1M context on Opus Artifacts for code/docs Lowest hallucination rate in my testing	Sources every claim Fast, current answers Pro Search runs multi-step research Spaces for persistent context	Native Google Workspace integration Very long context (1M+) Deep Research feature Free tier is generous
Weaknesses	Terminal-based — learning curve Can't be used without Claude subscription	Image generation is weak No native web search on all tiers	Not a general chatbot Answers can be shallow on complex topics	Writing quality trails Claude Over-refusals on edge content UI is cluttered
Kai's verdict	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
