ClearCheckout
Built at Meta Global AI Developer Hackathon · Oct 26, 2026 · Remote
ClearCheckout helps blind and low-vision shoppers get through a confusing checkout while staying in control of every action. The submission combines an accessible web app with real accounts and saved reading preferences, a guided demo store, and an installable Chromium (MV3) extension. It repairs unnamed controls only when reliable DOM context exists, and offers keyboard navigation through cart, delivery, and review. Meta models add complementary help. Muse Spark 1.3 Contributor explains the order and the next step. Muse Voice Transcribe turns approved audio into a transcript the shopper reviews before applying an allowed navigation command. Muse Image 1.0 supplies a clearly labeled illustrative product scene, and SAM 3.1 locates a selected object for highlighting and magnification. The shopper reads the authoritative total and types an exact confirmation phrase. Changing the cart or delivery invalidates that phrase. AI and voice cannot confirm an order. Every demo payment is explicitly simulated: no card details are collected, no money moves, and the extension never submits a merchant payment. All four model integrations were verified with live API calls on 2026-11-04. Hands-on testing with blind and low-vision shoppers is the next step.
