Command-line audio and video downloader supporting thousands of sites: pick formats and quality, grab subtitles and metadata, and merge or transcode with FFmpeg. The actively maintained fork of youtube-dl.

Pipes live streams from Twitch, YouTube and many other platforms to a local player, or saves them to video files with --output or --record, for keeping and re-editing replays of your own or partners' streams. Viewing needs a player like VLC. Only record content you have rights to.

One command extracts or summarizes web pages, PDFs, YouTube videos, podcasts and media files, with JSON output. Summaries can use many model APIs, local models or a logged-in Codex or Claude CLI; plain extraction needs no key. Also has a browser sidebar extension.

Cuts long videos like podcasts, webinars, livestreams and interviews into captioned vertical shorts, with optional dubbing and publishing to TikTok, YouTube and more. Hosted version needs an API key (free tier is watermarked and time-limited), or self-host with Docker and your own keys.

Lets Claude Code watch videos: extracts frames with ffmpeg and transcribes timestamped audio from local files or YouTube links, to review footage, summarize lectures or find on-screen text. Needs Node.js 20+ and ffmpeg (yt-dlp for YouTube); transcribe with local Whisper or a Gemini/OpenAI key.

YouTube channel assistant: lets agents upload videos, edit titles, descriptions and thumbnails, and manage playlists, captions, comments and live streams; also works as a CLI. Requires enabling the YouTube Data API in Google Cloud and creating OAuth credentials; daily API quotas apply.

Fetches captions and transcripts for YouTube videos and Shorts, with language selection and fallback, optional timestamps and sponsor segments filtered by default. No API key for transcripts; the optional visual analysis tool needs a TwelveLabs API key and a direct video URL.

Community YouTube server built on the YouTube Data API: look up video and channel data, fetch transcripts, browse playlists, and filter creators by subscriber count and upload frequency for influencer scouting. Needs a YouTube Data API key (daily quota) and Node.js.

Uses yt-dlp to pull YouTube subtitles into the agent, so asking it to summarize a video gets you the key points; handy for teachers prepping lessons, researchers and creators. No API key, but needs yt-dlp (Homebrew or WinGet) and Node.js.

Skill pack for YouTube creators with 14 subcommands: channel audits, video SEO, retention-focused scripts, hooks, thumbnail briefs, content calendars, and Shorts and cross-platform repurposing. Works with data you provide; add a YouTube API key or DataForSEO for live data.

Official BibiGPT skill: hand agents YouTube, Bilibili, podcast or local audio and video to get summaries, timestamped transcripts, chapter notes and mind maps. Needs a BibiGPT account (free tier has daily limits) plus its desktop app (with the bibi CLI) or an API key.

Official VideoDB skills: agents ingest video from local files, URLs, YouTube or live streams, then transcribe, index, search clips by content, generate subtitles, edit and dub, returning playable links. Needs Python 3.9+ and a VideoDB API key (free credits on sign-up).
