Pricing	Part of Claude Pro/Max/Team plans	Free + $20/mo Advanced (bundled with 2TB Drive)	Free + $20/mo Pro	Free (open source) + whatever API you use

Strengths	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	Sources every claim Fast, current answers Pro Search runs multi-step research Spaces for persistent context	Works in any terminal Auto-commits changes with meaningful messages Works with any model (Claude, GPT, local) Minimal learning curve
Weaknesses	Terminal-based — learning curve Can't be used without Claude subscription	Writing quality trails Claude Over-refusals on edge content UI is cluttered	Not a general chatbot Answers can be shallow on complex topics	Terminal-only Less agentic than Claude Code Setup on Windows is fiddly
Kai's verdict	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.	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	A-tier. The right answer if you want open-source + terminal-native + model-agnostic.
