|---|---|---|---|---|
| Tagline | AI search done right. Cited answers, not chat theater. | Marketing-first AI writing. Brand voice + campaign tools. | A digital wallet that lets AI agents spend on your behalf — without ever seeing your actual card number. | The one that actually gets text in images right. |

| Best for | Replacing Google for any question where you want a cited answer in seconds. | Marketing teams that need brand-consistent output at scale. | Anyone running autonomous AI agents (shopping bots, booking assistants, personal AI) who wants delegated payment capability without handing over raw card data. | Anything with text — posters, ads, album covers, slide decks. |

| Kai's verdict | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency. | 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 text-in-image. Use this for posters, Midjourney for art. |
