YouTube AI Video Summarizer — Gemini Brief, Q&A & Transcript

Turn YouTube videos into briefs, answers and transcripts with AI. Paste video links, a channel or a search. Google's Gemini AI watches and listens to each video and gives you a summary, the key points and chapters with clickable timestamps, answers to your own questions, your own JSON fields, and if you want, a full timestamped transcript.

🤖 Gemini AI reads the video itself (picture + sound) · ⏱️ Every moment links to that second of the video · 🌍 Output in 25 languages · 🗣️ Transcripts also for videos without captions · 💵 A brief is $0.02 per 10 minutes of video, transcripts $0.004 per minute · 🚫 No login, no API key

🎯 What you get for each video

Output	What it is
AI brief (on by default)	tldr (one sentence), summary (at most 120 words), 3–8 keyPoints with timestamps, chapters with timestamps (YouTube's own when the creator made them, otherwise written by the AI), topics
Your questions	up to 5 questions answered from each video, each answer with the timestamp where it is said or shown. If the video doesn't answer a question, it says so and you are not charged for it
Your JSON schema	your own fields (for example products shown, prices, a verdict), filled from each video into extracted
AI transcript	a timestamped transcript of everything said, in the language spoken, written by the AI from the audio. Works for videos without captions

Every timestamp comes as startSeconds, a readable timestamp (3:16) and a url such as https://youtu.be/MBRqu0YOH14?t=196 that opens the video at that second. The AI's timestamps are checked against the video's length, and any that fall outside the video are removed.

The brief, your questions and your schema all come from one AI read of each video. YouTube's own data is in the same row: title, channel, publish date, views, likes, comment count, length, description and thumbnail.

🚀 How to use it

Summarize videos. Paste links: watch links, youtu.be links, Shorts or video ids.

{ "videoUrls": ["https://www.youtube.com/watch?v=MBRqu0YOH14", "https://youtu.be/dQw4w9WgXcQ"] }

Ask your own questions, and get the brief in Spanish:

{ "videoUrls": ["https://www.youtube.com/watch?v=MBRqu0YOH14"], "questions": ["What does optimistic nihilism mean?", "Which books are recommended?"], "outputLanguage": "es" }

Pull structured data from product reviews, using your own JSON schema (or just {"field": "what to put in it"}):

{ "searchQueries": ["best robot vacuum 2026"], "maxVideos": 5, "includeBrief": false,
  "extractionSchema": { "products": "Products reviewed, with brand", "winner": "The product the reviewer recommends", "pricesMentioned": "Prices said in the video" } }

Get transcripts of a channel's latest videos up to 30 minutes long:

{ "channels": ["https://www.youtube.com/@kurzgesagt"], "maxVideos": 10, "maxVideoMinutes": 30, "includeBrief": false, "includeTranscript": true }

Other options: channelSortBy (newest or popular), searchSortBy (relevance, date or views), country (the country searches run from), and outputLanguage (en, es, pt, fr, de, hi, ja, … or original, which uses the language spoken in the video).

• aiStatus tells you what happened. done means you got everything you asked for. partial means you got part of it. skipped means the video was not sent to the AI (too long, live or upcoming, or its AI read would not finish before your run's timeout). refused means the AI could not open the video because it isn't public. failed means the AI request failed. off means the AI was unavailable on this run. aiNote explains anything missing in plain words.
• aiCharged shows what each row was charged.
• chaptersSource is youtube when the creator made chapters (those are used exactly as they are), otherwise ai.
• answers[].found is false when the video doesn't answer the question. Those answers are free.
• The AI writes the brief and answers. They are usually right, but check anything important by following the timestamp link.

The dataset has five table views: Briefs, Key moments, Answers, Transcript and YouTube details. The run's key-value store holds RUN_REPORT (how the run ended, the videos skipped and why, and what was charged), plus FAILED_INPUTS when needed (channels that don't exist, unavailable videos, and inputs YouTube blocked, none of them charged).

💵 Pricing

You pay per event, per video. Minutes are counted on the whole video.

Event	When	Price
Actor start	once per run (per GB of memory; the default 256 MB = 1)	$0.002
AI video read (per 10 min)	per started 10 minutes of each video the AI read for your brief, questions or JSON schema (one read covers all three)	$0.02
AI answer	each question the video answers; your JSON schema filled = 1 per started 1,000 characters of filled JSON (a typical 5–10 field schema = 1)	$0.002
AI transcript minute	per started minute of each video transcribed (only when AI transcript is on)	$0.004

Examples:

• A brief of a 7-minute video costs $0.002 + $0.02 = $0.022.
• A 25-minute video with a brief and 2 answered questions costs $0.002 + 3 × $0.02 + 2 × $0.002 = $0.066.
• A transcript of a 7½-minute video costs $0.002 + 8 × $0.004 = $0.034.
• Briefs of a channel's 5 latest videos (each under 10 minutes) cost $0.002 + 5 × $0.02 = $0.102.

What is never charged:

• videos longer than your maximum length, and videos skipped because your run's timeout left too little time for the AI;
• live streams and upcoming premieres;
• private, deleted or unavailable videos, and videos the AI cannot open;
• videos where the AI failed or gave an unusable answer;
• questions the video doesn't answer, and a JSON schema the video gives nothing for or the AI rejects;
• everything on a run where the AI is unavailable.

One exception: a transcript is charged for the minutes the AI listened to, even when nobody speaks and the transcript comes back empty.

If you set a maximum cost per run, the actor never sends a video to the AI unless your limit covers everything that video could be charged.

❓ FAQ

Do I need a YouTube account, cookies, or a Gemini or OpenAI API key? No. The actor reads YouTube's public pages like any logged-out visitor, and the AI runs on our Gemini account. You don't need any key.

How does the AI read the video? It uses Gemini's official YouTube video input: Google fetches the public video and the AI watches it (about one frame every 5 seconds, at low resolution) and listens to the full soundtrack. Nothing is downloaded. Because the AI hears the audio itself, transcripts and summaries also work for videos without captions.

Which videos work? Public videos and Shorts. Private and deleted videos are listed in FAILED_INPUTS. Videos the AI is not allowed to open come back with aiStatus refused: unlisted, members-only, age-restricted and region-locked videos, and some live-stream replays. Neither kind is charged. The maximum length is 180 minutes; the default is 60, and longer videos are skipped and not charged.

What do I send to Google, and is my data private? To make each video's output, the actor sends Google's Gemini API the video's public link, its title, channel name, length, description (first 1,500 characters) and chapter list, and your questions and JSON schema. Nothing else about you or your account is sent. This goes through Google's paid Gemini API under Google's terms. YouTube data is read without logging in.

Is it legal to use this on YouTube videos? The actor only reads what anyone can see on YouTube without signing in. It does not download or redistribute videos. It returns summaries, short quotes and transcripts for analysis. Collecting public data is generally legal, but you're responsible for how you use the results. Transcripts and summaries can be covered by the creator's copyright, so use them for research, analysis, accessibility or your own notes, not to republish someone else's content. Results can include names and channel handles, which can count as personal data, so follow privacy laws such as GDPR, PIPEDA and CCPA. If you're unsure, ask a lawyer. More on this: Is web scraping legal?

How accurate is it? The AI is good at summarizing, but it can make mistakes, especially with names, numbers and timestamps. Every point and answer has a timestamp link so you can check it in seconds. Timestamps outside the video are removed automatically. The transcript is written by the AI from the audio, not copied from YouTube's captions.

Can I get the brief in another language? Yes. Set outputLanguage to one of 25 languages, or to "Same as the video". The transcript always stays in the language spoken in the video.

What if the AI is unavailable? You still get rows with YouTube's details for the first 5 videos, with aiStatus set to off. The run stops there and nothing is charged beyond the start. Run it again later.

What happens if YouTube blocks a request? Each request is retried on fresh IPs, starting with Apify datacenter IPs and then the proxy in your input (residential by default). A video that stays blocked is listed in FAILED_INPUTS and not charged. If YouTube blocks the run from the start, the run stops at once and says so, instead of spending your money.

What if my run's timeout is short? The actor stops starting new videos shortly before your timeout and keeps every row already saved. A video whose AI read would not finish in the time left (estimated from its length) comes back with YouTube's details, aiStatus skipped and a note, is not charged, and the actor goes on to the next video. The AI usually takes 5–15 seconds per video but sometimes 2 minutes, so give runs with many videos a few minutes.
