Check if yt-dlp is installed - install if needed 2. Try manual subtitles first (--write-sub) - highest quality, human-created 3. Fallback to auto-generated (--write-auto-sub) - usually available 4. Convert to plain text - deduplicate and clean up VTT format 5. Save to output directory as a markdown file with filename based on video title 6. Automatically polish - remove filler words, fix grammar, add section headers, maintain 100% fidelity 7.
