Strengths	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	Runs locally, edits your actual files Strong on large codebases with 1M context Great at multi-step tasks	Actually uses websites — fills forms, clicks, checks out Built into ChatGPT Good for repetitive web tasks
Weaknesses	Not a general chatbot Answers can be shallow on complex topics	Writing quality trails Claude Over-refusals on edge content UI is cluttered	Terminal-based — learning curve Can't be used without Claude subscription	Slow vs doing it yourself Breaks on complex auth flows $200/mo gate
Kai's verdict	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.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	B-tier. Still early. Manus is more flexible for less money.
