Underdog launches on-device agent payments with Stripe Link in a local browser
jeff_weinstein · x · 2026-10-13
Underdog, a private on-device AI assistant, can now use the browser locally and securely pay for anything online via Stripe Link.
In shopping flows, Underdog finds the best option, spins up a one-time Link card for the exact amount in a local browser, and waits for user approval before paying — billed as the first on-device Agent Payment. Built with 0xSigil's team, now open for feedback.
