CallOrder

CallOrder lets seniors order food and groceries with a single phone call. No app, no screen, no checkout. Delivery apps are a real barrier for older adults: tiny text, complex menus, and multi-step payment. With CallOrder they just call a number and talk. A voice agent built on Meta's Muse models answers in short, polite sentences. It asks a first-time caller for their address, finds the store and dish, asks for required options such as spice level, and reads the whole order back. Nothing is placed until the caller agrees, and a separate Muse Spark check judges any way of saying yes, in Korean or English. When the caller rings back while the order is on its way, the call opens with how many minutes are left. It runs today on a real Korean number (070-5276-7404) and a US number (+1 515-349-6768). Each call lives in its own Cloudflare Durable Object that streams phone audio through speech-to-text, two LLM agents with tool calling, and text-to-speech. Stores get a live order board where they accept or decline orders, and the team gets a developer view with every call's transcript, timing, tool calls, latency and cost (about 4 cents per call). A web call screen shows real calls live, so you can watch the conversation as it happens. Demo video: https://youtu.be/lLVrAXMHL50 For reviewers 1.
