name: youtube-asr-summarize description: "Summarize YouTube videos with NO subtitles by doing local ASR (yt-dlp + faster-whisper) and extracting a few screenshot frames via ffmpeg.

  --model small \
  --lang zh \
  --frames 1 \

這個工具能本地完成 YouTube 影片轉寫和總結，無需付費 API，隱私性好。功能流程完整，文件易讀。缺點是摘要生成針對特定領域（中文金融）最佳化明顯，對其他內容型別的總結效果可能不佳。另外缺少規範的依賴宣告和測試，對普通使用者不夠友好。總體屬於可用但需針對性使用的工具。
