The tutorial covers creating a real-time polling app using Twilio Sync and Laravel PHP, focusing on extending Laravel's default broadcast driver to use Twilio Sync for real-time updates. It involves building a Voting component with Chart.js to visualize poll results, creating a Candidate model and migration, defining routes and controller actions, and implementing event broadcasting with Twilio Sync. The application allows users to cast votes in real-time, and the changes are reflected across multiple browser tabs.
