YouTube Free AI Summary adds a button to YouTube that grabs the current video's subtitles and drops them straight into a freshly opened AI chat — your choice of Google AI Studio, Gemini, ChatGPT, Claude, or Grok — ready to be summarized.

It is built to solve the two problems other summary scripts run into: they can't get the subtitles of restricted videos, and long transcripts don't reach the AI in one piece, so you end up with a summary of only part of the video.

The Summarize button on a video page

Once installed, a Summarize button (outlined in red) appears next to the like / dislike buttons on the video page. One press and it starts.

Features

  • Completely free — No API key, no payment, no subscription; you only need to be logged into the AI service you picked
  • One click — Adds a button to the YouTube video page: press it and the subtitles are captured, your AI opens, and the summary starts
  • Choice of AI service — Google AI Studio, Gemini, ChatGPT, Claude, or Grok — pick your usual one in the settings
  • Works on restricted videos — Members-only, age-restricted and region-locked videos can be summarized too, as long as you can watch them yourself
  • Long videos aren't cut short — The whole transcript reaches the AI, so the summary won't stop halfway through
  • Summarize without opening the video — Hover any video thumbnail for a button that summarizes it right there
  • Custom prompt — Write your own prompt in the settings to control how the AI summarizes and what it focuses on
  • 10 interface languages — English, 繁體中文, 简体中文, 日本語, 한국어, Español, Français, Deutsch, Português (BR), Русский

How to use

  1. Install Tampermonkey, then install this script
  2. Open any YouTube video that has subtitles
  3. Click the Summarize button next to the like/dislike buttons — the subtitles are captured and your chosen AI opens with the prompt already filled in
  4. Click the gear next to it to open settings: AI service, interface language, custom prompt, timestamps, auto-submit, preferred subtitle languages

Requirements

  • Tampermonkey, or another userscript manager
  • A logged-in account on the AI service you pick — no API key, no payment, no subscription

Privacy

  • No data collection, no analytics, no server of the author's involved
  • Subtitles are read from YouTube itself (same-origin requests from the page) and handed to the AI tab you chose; nothing else leaves your browser
  • Settings are stored locally by your userscript manager
