Build a YouTube Video Summarizer with Python and Whisper API
Three hours of conference talk. You have 20 minutes. The usual move is 2x speed, aggressive skipping, and hoping the important bits weren't in the sections you blew past. There's a better option: a script that downloads the audio, transcribes it, and hands it to Claude with a prompt that extracts exactly what you care about. This tutorial builds that. You'll need Python 3.10+, an OpenAI API key for Whisper transcription, and an Anthropic API key for the summarization step. The whole thing ships as a single CLI script.
