| 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 if you already pay Gemini. B-tier standalone. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier. Great price/performance. Go here if ElevenLabs is too expensive. |
