The tool converts YouTube videos into structured Mermaid diagrams by textual content. Beyond just visualization, it has potential use cases like: * Extracting keywords and recurring themes to help with SEO optimization * Mapping out processes and workflows described in video content * Summarizing and organizing complex video material into clear diagrams (great for learners, educators, or technical teams) * Creating searchable visual representations of long-form content Tech Stack: Built a full-stack application using React Router v7 and a custom Express.js backend (no database). Integrated the YouTube API for transcript scraping and the Gemini AI API for intelligent content generation and diagram automation. Deployed to AWS EC2 (Ubuntu) via SSH, with fully automated CI/CD using GitHub Actions.
