Summarize

A solid CLI that pulls text from URLs, PDFs, and YouTube videos, then feeds them to your choice of LLM for summarization. Handles the annoying extraction work so you don't need to copy-paste articles or hunt for YouTube transcripts. Supports all the major AI providers and has sensible defaults like Gemini Flash for speed. The YouTube transcript extraction is hit-or-miss depending on the video, but when it works it saves you from manually transcribing or installing yt-dlp. Good fallback options with Firecrawl for stubborn websites.

Files

Summarize

Fast CLI to summarize URLs, local files, and YouTube links.

When to use (trigger phrases)

Use this skill immediately when the user asks any of:

"use summarize.sh"
"what's this link/video about?"
"summarize this URL/article"
"transcribe this YouTube/video" (best-effort transcript extraction; no yt-dlp needed)

Quick start

summarize "https://example.com"
summarize "/path/to/file.pdf"
summarize "https://youtu.be/dQw4w9WgXcQ" --youtube auto

YouTube: summary vs transcript

Best-effort transcript (URLs only):

summarize "https://youtu.be/dQw4w9WgXcQ" --youtube auto --extract

If the user asked for a transcript but it's huge, return a tight summary first, then ask which section/time range to expand.
