Tagline	OpenAI's browser agent. Clicks and types on websites for you.	AI search done right. Cited answers, not chat theater.	A digital wallet that lets AI agents spend on your behalf — without ever seeing your actual card number.	Open-source VS Code agent. Reads + writes + runs.
Category	Agents	Research	Agents	Coding
Pricing	Included with ChatGPT Pro $200/mo	Free + $20/mo Pro	Free for consumers; standard Stripe per-transaction fees for merchants	Free (open source) + your API costs
Best for	Power users willing to pay $200/mo for a browser bot.	Replacing Google for any question where you want a cited answer in seconds.	Anyone running autonomous AI agents (shopping bots, booking assistants, personal AI) who wants delegated payment capability without handing over raw card data.	VS Code users who want agentic coding without changing IDEs.
Strengths	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	First mainstream wallet with a built-in agent authorization layer — AI agents get one-time-use cards, not your real credentials OAuth-based approval flow means you review every agent spend request before payment credentials are shared 250M+ existing Link users means instant network coverage at hundreds of thousands of Stripe-powered merchants Developer-friendly: agent builders can use Link's wallet infra instead of rolling their own payment rails Subscription tracking, auto payment-method updates, and 90-day purchase protection bundled in	Free extension for VS Code Plan + Act modes Model-agnostic (Claude, GPT, local) Sees terminal output and iterates
Weaknesses	Slow vs doing it yourself Breaks on complex auth flows $200/mo gate	Not a general chatbot Answers can be shallow on complex topics	Stablecoin, agentic token, and BNPL agent-payment support is still 'coming soon' — traditional cards only at launch Per-transaction approval flow can be tedious for high-frequency agent tasks until spending-limit presets ship Merchant adoption for agent checkout paths is still early; real-world agentic commerce coverage is thin	Can burn tokens fast if not watched Less polished than Cursor
Kai's verdict	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.	Stripe Link is the most credible first move toward a real agentic payment layer — the one-time-use card model is genuinely clever, and the existing merchant network gives it a head start no startup wallet can match. But the 'approve every transaction' UX will get old fast, and the hard part (autonomous spending with guardrails) is still on the roadmap. (Verdict pending Phi's full review.)	A-tier. Best free agentic option in VS Code. Use with Claude for best results.
