In this tutorial, you will learn how to build a Next.js video conferencing app that supports video calls with live transcriptions and an LLM-powered meeting assistant. The app uses the Stream Video SDK for video call functionality, AssemblyAI for real-time transcription and LLM functionality, and Node.js 18.17 or later to build with Next.js. The final app allows users to start a video call, transcribe conversations in real-time, and ask questions during the call that are answered by an AI assistant.
