You need
| Account | Why | Free or paid | Plan |
|---|---|---|---|
| mlx-whisper (local transcription, Apple Silicon) | Word-level transcripts for rough cuts, captions, chapter timestamps and YouTube descriptions, all offline. | Free | Free; needs an Apple Silicon Mac with 16 GB+ RAM. Model whisper-large-v3-turbo downloads once (about 1.6 GB). |
| ffmpeg + ffprobe | Every cut, mux, loudness pass, proxy, contact sheet and platform encode. The delivery encoder uses h264_videotoolbox on Apple Silicon. | Free | Free (Homebrew build includes VideoToolbox). |
| Fathom (call recorder) | Client-side call recorder used by clients for lessons and sales calls. The fathom-download skill pulls the MP4 and speaker transcript from a share link; the voc-ingest scripts pull whole libraries through the API. | Free tier available | Free for recording and sharing; the API and webhooks need Fathom Premium or Team. |
| yt-dlp | Downloads YouTube, TikTok and Instagram video, auto-captions and comments for vaults, B-roll, MIDI extraction and quote verification. | Free | Free. |
| Claude Code (Anthropic Claude Pro or Max) | The AI operator every system runs through. Skills, hooks, memory, MCP servers and the Brain plugin all load inside Claude Code. | Paid | Claude Pro (20 USD/mo) works for light use; Max (100 USD or 200 USD/mo) for daily multi-hour sessions. Anthropic terms require each user to hold their own subscription; never share a login. |
| Python 3.12 + uv | Runs every pipeline script (video gates, library export, research cache, Brain export, PDF generator, MIDI tools) inside per-project virtual environments. | Free | Free. |
