Automated Technical Documentation Generator from YouTube Video URL: A Multi-Module AI-Powered Web Application
Abstract
The rapid proliferation of video-based learning content on platforms such as YouTube has created significant challenges for students, developers, and professionals who need to extract, retain, and reference technical knowledge from long-form instructional videos. Manual documentation is costly, existing summarization tools lose technical fidelity, and no current system addresses the full pipeline from a raw video URL to formatted, downloadable documentation. This paper presents an Automated Technical Documentation Generator, a nine-module AI-powered web application that accepts any YouTube URL and produces structured professional documentation in under 90 seconds. The system comprises modules for transcript extraction with automatic chunking, AI-based content type classification, LLM-driven chunk-and-merge documentation generation, a multi-turn Q&A chatbot, multi-format export in PDF, DOCX, and HTML, a usage history and analytics dashboard, a goal-driven Video Recommender, and a Cognitive Load Analyzer grounded in Sweller's Cognitive Load Theory. An automatic fallback router ensures near-100% availability across eight free LLM providers. Results on twenty test videos across five content types show transcript coverage exceeding 93% and strong alignment between Cognitive Load scores and independent educator assessments.
