YouTube Video Automatic Transcription and Intelligent Content Analysis Workflow
This workflow automatically receives YouTube video links through an interface, extracts video information and subtitles, and utilizes a large language model to perform structured summarization and analysis of the subtitles, generating clear technical summaries. At the same time, it provides real-time feedback of the analysis results to the caller and pushes the video title and link via Telegram, significantly enhancing the efficiency of video content processing and helping users quickly understand the core information of the video. It is applicable in various fields such as education, content creation, research, and enterprise knowledge management.
