How to Summarize a YouTube Video (Free, in Any Language)

The fastest way to summarize a YouTube video is to paste its link into a free YouTube video summarizer and read the key points in a few seconds. You can also ask Gemini, which can read YouTube videos directly, or paste the video's transcript into ChatGPT or Claude for exactly the kind of summary you want: bullet points, chapters, study notes or action items.

1Use a free YouTube video summarizer

The URL to Text Video Summarizer turns a YouTube link into a structured summary. It's free, needs no account, and writes the summary in the language you choose, whatever language the video is in.

1. Open the Video Summarizer.
2. Under Summary language, leave Same as the video or pick one of 33 languages (English, Spanish, Portuguese, French, German, Hindi, Arabic, Japanese, Korean, Chinese and more).
3. Paste the YouTube link in the Paste a link box. Regular videos, Shorts and youtu.be links work. You can paste the link together with the video title or other text; the link is picked out.
4. Click Summarize. You'll see "Getting YouTube's captions…" and then "Summarizing…".
5. Read the result, then click Copy or Download .md.

Every summary has the same three parts:

• Summary: two to four sentences on what the video is about and its main point.
• Key points: 5 to 10 bullets with the specific details: names, numbers, steps and claims.
• Takeaways: 2 to 4 bullets on what to do or remember.

Click the Transcript tab to see the full text the summary was written from, and Download .txt to save it.

How it works

For YouTube videos with captions, the summarizer reads YouTube's captions directly. Nothing is downloaded, which is why it's quick. It also works with TikTok, Instagram, Facebook, X, Vimeo, Loom and podcast links, and with files you upload (MP3, M4A, WAV, MP4, MOV and more, up to 95 MB). Those are transcribed first with Whisper, an AI speech recognition model, then summarized.

Limits: up to 15 minutes per video without an account, or up to 60 minutes when you sign in (free). Free use allows 5 summaries an hour without an account and 30 an hour signed in. For longer videos, see section 6.

Tip: Want a translation of the whole video rather than a summary? The Video Transcript Translator translates every word into any of the same 33 languages.

2Use YouTube's Ask button

YouTube has its own AI assistant, powered by Gemini, on the watch page of many videos. It's called Ask (YouTube's help pages call it "Ask YouTube"), and you can ask it to summarize the video or answer questions about it without leaving the page.

1. Open the video in the YouTube app or on youtube.com, signed in.
2. Tap or click the Ask button below the video, next to buttons like Share.
3. Choose one of the suggested prompts, or type your own, such as "Summarize this video in 5 bullet points."
4. Ask follow-up questions in the same panel. Answers often include timestamps you can tap to jump to that part.

On a smart TV or game console, press up or down on the remote while watching to show the video details, then select Ask.

Limitations:

• It only appears on select videos, in supported countries and languages, and only for signed-in users who meet the minimum age (13 or older in most countries). It isn't available for supervised accounts or in YouTube Kids.
• You can't pick the output language or format the way you can with a summarizer or a chatbot.
• Answers come from an AI model and can be wrong. YouTube keeps conversations for 45 days, and reviewers may read some of them, so don't type anything private.

If you don't see the button, the video or your account isn't eligible yet. Use one of the other methods.

3Summarize a YouTube video with Gemini

Google's Gemini can read public YouTube videos from a link, which ChatGPT and Claude generally can't. It works at gemini.google.com and in the Gemini app.

1. Go to gemini.google.com (or open the Gemini app) and sign in with your Google account.
2. Paste the YouTube link into the prompt box, followed by your request. For example: "Summarize this video in 7 bullet points, then list the 3 main takeaways: https://www.youtube.com/watch?v=VIDEO_ID"
3. Press Enter.
4. Ask follow-ups in the same chat: "What did they say about pricing?", "Turn this into a checklist", or "Answer in Spanish."

You can also ask Gemini to find a video first ("Find videos on how to repot an orchid"), then say "Summarize the first video."

Limitations:

• You need to be signed in, with Keep Activity turned on in Gemini's activity settings, or YouTube features aren't available.
• Work and school (Google Workspace) accounts may have this turned off by an admin.
• In testing by reviewers, Gemini does best on videos with captions. If it says it can't access the video, or the answer sounds generic, use the transcript method below instead.
• It may summarize from the title and description when it can't read the video. Ask it to "include timestamps for each point" and spot-check one or two.

4Summarize with ChatGPT or Claude using the transcript

ChatGPT and Claude are excellent at summaries, but they usually can't watch a YouTube video from its link. ChatGPT may search the web and summarize what other pages say about the video, or just the description, which isn't the same thing. The reliable way is to give them the video's words:

1. Paste the video's link into the free YouTube Transcript Generator. Tick Include timestamps if you want the summary to point to moments in the video, then click Convert.
2. Click Copy.
3. Open ChatGPT or Claude and start a new chat.
4. Paste one of the prompt templates below, then paste the transcript underneath it.
5. Press Enter. Ask follow-ups in the same chat ("Expand point 3", "Make it shorter").

For a very long transcript, save it as a .txt file and attach it with the + button in ChatGPT or Claude instead of pasting.

Prompt templates for different kinds of summaries

Copy a template, paste it into the chat, and paste the transcript below the last line.

Bullet summary

Summarize this YouTube video transcript.
- Start with 2 sentences on what the video is about and its main point.
- Then give 7 to 10 bullet points with the most useful specifics (names, numbers, steps, claims).
- End with 3 takeaways.
Only use what the transcript says. If something is unclear, say so.

Transcript:

Chapters with timestamps (turn on Include timestamps first)

Here is a YouTube transcript with timestamps like [12:34].
Split it into 6 to 12 chapters by topic. For each chapter give:
- the start time, exactly as written in the transcript
- a short chapter title
- one sentence on what is covered
Format each as: 12:34 Title: summary. Use only timestamps that appear in the transcript.

Transcript:

Study notes

Turn this lecture transcript into study notes for a student.
Use headings for each main topic, bullet points under each, and bold key terms.
Add a "Key terms" list with one-line definitions, then 5 quiz questions with answers at the end.
Keep the explanations simple and don't add facts that aren't in the transcript.

Transcript:

Action items

This is a transcript of a tutorial (or meeting, or talk).
List every concrete action the viewer is told to take, as a numbered checklist in the order given.
Include any tools, settings, links or numbers mentioned for each step.
Then list any warnings or common mistakes mentioned.

Transcript:

Summary in another language

Summarize this transcript in [Spanish] for someone who hasn't watched the video.
Write 1 short paragraph, then 5 bullet points. Keep names and product terms in their original form.

Transcript:

Tips for better results:

• Say who it's for and how long. "For a busy manager, in under 150 words" beats "summarize".
• Ask it to stick to the transcript. "Only use what the transcript says" cuts down invented details.
• Use timestamps to check. Ask for the time behind each point, then click through to verify the ones that matter.
• Name the format. Table, checklist, email, tweet thread, or Markdown notes for Notion or Obsidian.

5Use a browser extension

If you summarize videos every day, a browser extension can add a summary button right on YouTube's page. The best known is YouTube Summary with ChatGPT & Claude by Glasp (Chrome and Firefox), which pulls the video's transcript and sends it to the AI chat of your choice, with a customizable prompt.

1. Install it from the Chrome Web Store (or Firefox Add-ons).
2. Open a YouTube video. The extension adds a panel beside the video with the transcript.
3. Use its summarize button to send the transcript and your prompt to ChatGPT, Claude or another AI chat.

Before you install any extension: check its permissions and reviews, and remember it can see the pages you visit. Free tiers of many summary extensions limit how many videos you can do, and like every transcript-based tool, they need the video to have captions.

6Summarize long videos, podcasts and lectures

A 1-hour video is roughly 9,000 words of transcript, a 3-hour podcast close to 30,000. Gemini, ChatGPT and Claude can usually take in that much, but summaries of very long inputs get vague: the middle gets less attention than the start and the end. For better results, summarize in parts.

1. Get the whole transcript with the YouTube Transcript Generator with Include timestamps on. It reads the captions, so there's no length limit.
2. Split it into parts of about 20 to 30 minutes each. With timestamps, that's easy: cut at [20:00], [40:00], and so on.
3. In one chat, paste each part with: "This is part 1 of 4 of a video transcript. Summarize it in 8 bullet points with timestamps. Wait for the next part."
4. When all parts are in, ask: "Now combine the part summaries into one summary: an overview paragraph, the 10 most important points, and the key takeaways."

The result keeps the details from every part of the video, not just the first and last few minutes.

Shortcuts:

• Videos up to 60 minutes: sign in (free) and the Video Summarizer handles them in one go.
• Only care about one topic? Skip the full summary and ask: "Find every part of this transcript that talks about [topic], with timestamps."
• If the video has no captions, transcribe it first with Audio & Video to Text, then summarize the text.

How to make sure a video summary is accurate

Any AI summary can miss a point or get one wrong. A few habits help:

• Check the captions are good. Summaries built on poor auto-generated captions inherit their mistakes, especially with names, numbers and jargon. If the transcript looks garbled, transcribe the audio instead.
• Watch for confident filler. A summary full of general statements ("the speaker discusses the importance of...") often means the model didn't have the real content. Ask for specifics, or switch to the transcript method.
• Verify numbers and quotes. Ask for timestamps and check anything you'll repeat or act on.
• Know what's missing. Transcripts only contain speech. Anything shown on screen but not said (slides, code, charts) won't be in the summary.
• Compare two tools for important videos. If the Video Summarizer and ChatGPT agree on the key points, you can trust them more.
