- description
- Summarize YouTube videos with NO subtitles by doing local ASR (yt-dlp + faster-whisper) and extracting a few screenshot frames via ffmpeg. Use when the user asks to summarize the latest video from a channel and YouTube timedtext/subtitles are empty, or when no API tokens/keys should be used.
