| Kai's verdict | 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 for sales teams. B-tier for solo users. | S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing. | S-tier for open-source model APIs. The default in this space. |
