Building a YouTube Video Summarizer with Python and the GPT API

In an era of information overload, extracting key insights from long online videos is a highly valuable skill. This text-only course teaches you how to build a custom AI-driven summarization tool from scratch using Python and the GPT API. You will start with foundational concepts of web APIs, text processing, and prompt design before diving into practical implementation. By the end of this course, you will have a deep understanding of how to connect Python scripts to external language models to automate content synthesis. What you will learn: - Understand the foundational concepts of APIs, token limits, and text summarization workflows. - Extract and clean transcript data using Python libraries. - Configure secure authentication and environment variables for API integration. - Apply modern prompt engineering techniques to generate structured, high-quality summaries. - Implement asynchronous Python patterns to handle API requests efficiently. - Manage API rate limits and format outputs using modern Python type hints. This course starts with key definitions and environment setup, moving step-by-step through transcript extraction, prompt design, and API integration. It is designed for beginners with basic Python familiarity, requiring no prior experience with machine learning or natural language processing.
