Video Summarizer
Drops a video URL in, pulls out everything: MP4, MP3, subtitles, transcript, and an AI summary in a tidy folder structure. Works across 1800+ platforms through yt-dlp (YouTube, Bilibili, TikTok, Twitter, Vimeo, the usual suspects). The smart bit is the subtitle handling: tries manual subs first, falls back to auto-generated, and if neither exists, fires up faster-whisper with parallel transcription that automatically splits long audio at silence points. Auto-installs its own dependencies through uv. Honestly most useful when you need to reference video content without scrubbing through timelines, or when you're dealing with foreign language videos and need searchable text. First run downloads a 244MB model.
