AfterBooth
Built at Meta Global AI Developer Hackathon · Oct 26, 2026 · Remote
AfterBooth helps festivals, exhibitions and pop-up events pass leftover booth equipment to the next event or community before the teardown deadline. Display racks, storage bins and folding tables often need a new owner within hours, but a listing alone does not solve pickup timing, vehicle fit or competing requests. A giver photographs the booth, reviews an AI-generated inventory draft and confirms the items. A receiver describes what they need by voice or text. A Muse Spark agent searches available stock, checks vehicle fit and places a temporary hold through server tools. The server enforces quantity, pickup deadlines and concurrency; the receiver explicitly confirms the reservation. At pickup, a photo recount and segmentation check support handover verification, and the dashboard records reused quantities and estimated volume. Built with React, TypeScript, Spring Boot and PostgreSQL, AfterBooth connects AI output to inventory registration, allocation and handover. The demo shows two receivers competing for the last display rack: one receives a hold and the other an alternative, without overselling. The 50-second video is explicitly labeled recorded replay; live API verification is documented separately. Reuse statistics are application records, not measured environmental impact.
