File contents

grab 🫳

Download and archive content from URLs into organized folders.

Setup

Dependencies

brew install yt-dlp ffmpeg openai-whisper

Save Location

On first run, grab asks where to save files (default: ~/Dropbox/ClawdBox/). Config stored in ~/.config/grab/config. Reconfigure anytime with grab --config.

Transcription (Local Whisper)

Transcription runs locally via Whisper (turbo model) — no API key or network calls needed.

AI Summaries & Smart Titles (Optional)

Set OPENAI_API_KEY to enable:

AI-generated summaries of content
Smart descriptive folder names (from transcript/image analysis)

Without it, everything still works — you just won't get summaries or auto-renamed folders.
