The document describes the On The Same Page app, which aims to address challenges in sharing information and slide presentations among a large number of people simultaneously and instantly within physical vicinity without complex configuration or special devices. The app allows presenters to upload slides to the cloud and broadcast them to thousands of devices of audience members who have the app installed, enabling projector-less presentations. It works by slicing the WiFi access point so presenters can share with their audience through their devices over WiFi without an internet connection.
