	GitHub Copilot B	Stripe Link A	Perplexity S	Flux (Black Forest Labs) A
Tagline	Microsoft/GitHub's autocomplete. Deep VS Code + JetBrains integration.	A digital wallet that lets AI agents spend on your behalf — without ever seeing your actual card number.	AI search done right. Cited answers, not chat theater.	Open weights + strong photorealism. The open-source answer.
Category	Coding	Agents	Research	Image
Pricing	Free (limited) + $10/mo Pro + $19/mo Business	Free for consumers; standard Stripe per-transaction fees for merchants	Free + $20/mo Pro	API + open weights (Schnell is Apache 2.0)
Best for	Teams with GitHub already. Devs who don't want to change IDEs.	Anyone running autonomous AI agents (shopping bots, booking assistants, personal AI) who wants delegated payment capability without handing over raw card data.	Replacing Google for any question where you want a cited answer in seconds.	Developers + power users who want control and privacy.
Strengths	Great enterprise story Works in your existing IDE Chat + autocomplete	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	Sources every claim Fast, current answers Pro Search runs multi-step research Spaces for persistent context	Runs locally on a beefy GPU Very photoreal Best open-weight model
Weaknesses	Less agentic than Cursor/Claude Code Model quality varies	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	Not a general chatbot Answers can be shallow on complex topics	Harder to use than hosted tools Needs infra
Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	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.)	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	A-tier. S-tier if you self-host. The reason open-source image gen matters.
