Tagline	Anthropic's CLI agent. Opus-powered, operates on your repo directly.	Anthropic's flagship — best reasoning + longest useful context.	OpenAI's browser agent. Clicks and types on websites for you.	AI search done right. Cited answers, not chat theater.
Category	coding	chat	agents	research
Pricing	Part of Claude Pro/Max/Team plans	Free + $20/mo Pro + team/enterprise	Included with ChatGPT Pro $200/mo	Free + $20/mo Pro
Best for	Developers who want an agent, not autocomplete. Large refactors, tests, docs.	Long writing, code, careful thinking, documents over 50 pages.	Power users willing to pay $200/mo for a browser bot.	Replacing Google for any question where you want a cited answer in seconds.
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	Actually uses websites — fills forms, clicks, checks out Built into ChatGPT Good for repetitive web tasks	Sources every claim Fast, current answers Pro Search runs multi-step research Spaces for persistent context
Weaknesses	Terminal-based — learning curve Can't be used without Claude subscription	Image generation is weak No native web search on all tiers	Slow vs doing it yourself Breaks on complex auth flows $200/mo gate	Not a general chatbot Answers can be shallow on complex topics
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.	B-tier. Still early. Manus is more flexible for less money.	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
