| Tagline | Run any open-source AI model with an API call. | A digital wallet that lets AI agents spend on your behalf — without ever seeing your actual card number. | Google's research notebook. Turns your docs into a podcast. | Microsoft/GitHub's autocomplete. Deep VS Code + JetBrains integration. |

| Pricing | Pay per second of compute | Free for consumers; standard Stripe per-transaction fees for merchants | Free | Free (limited) + $10/mo Pro + $19/mo Business |
| Best for | Developers using open-source models (Flux, SDXL, Whisper, etc). | Anyone running autonomous AI agents (shopping bots, booking assistants, personal AI) who wants delegated payment capability without handing over raw card data. | Students, researchers, anyone with a stack of PDFs or a topic to learn. | Teams with GitHub already. Devs who don't want to change IDEs. |

| Kai's verdict | S-tier for open-source model APIs. The default in this space. | 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 study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. |
