Summario: AI YouTube Summarizer & Chat

Summarize any YouTube video with AI. Get key takeaways, timestamps, and chat — save hours of watch time.

───────────────────────────────────────────── 🎬 SUMMARIO — AI YOUTUBE SUMMARIZER & CHAT ───────────────────────────────────────────── Summario is a free AI YouTube summarizer for Chrome. It reads the transcript of the video you are watching and generates a summary, key takeaways, clickable timestamps, and a watch-or-skip verdict — in a sidebar on the YouTube page itself, in under 30 seconds. You can also ask the video questions in chat, and read the summary in any of 70+ languages, whatever language the video was spoken in. Summarize any YouTube video without leaving YouTube. No copy-pasting transcripts into a chatbot. No tab switching. One click. ───────────────────────────────────────────── 🚀 HOW TO SUMMARIZE A YOUTUBE VIDEO ───────────────────────────────────────────── 1. Install Summario and open any YouTube video. 2. Click "Summarize" in the Summario sidebar widget. 3. Read the quick TL;DR in a few seconds; the full breakdown finishes writing itself underneath. There is nothing to configure and nothing to paste. Summario detects the video you are on automatically, and it works on standard YouTube videos, Shorts, and YouTube Music. ───────────────────────────────────────────── 📦 WHAT YOU GET FROM EVERY VIDEO ───────────────────────────────────────────── • A one-line TL;DR — the entire video in a single sentence • Key takeaways — the points that actually matter, each savable • A watch-or-skip verdict — with the reasoning, so you can decide before you spend 45 minutes • A clickable timeline — every section timestamped; click to jump • AI chat — ask follow-up questions, answered from the transcript • Audience reaction — what the comments think, scored as a positive / mixed / negative percentage split ───────────────────────────────────────────── ✨ FEATURES ───────────────────────────────────────────── ⚡ QUICK SUMMARY, THEN THE DEEP ONE Summario gives you a TL;DR and the key points within seconds of clicking, while the full breakdown is still being generated. You skim first and go deep only if the video earns it. Most videos do not, which is the entire point. 🧠 FULL AI SUMMARY WITH TIMESTAMPS The complete YouTube summary includes key takeaways, a section-by- section timestamped timeline, and a watch-or-skip verdict. It handles podcasts, lectures, tutorials, interviews, keynotes, and earnings calls — anything with spoken content. Unlike a general-purpose video summarizer, Summario is built only for YouTube, so it reads the player, the chapters, and the comments too. ⏱️ CLICKABLE TIMELINE Every section of the video is timestamped, and clicking a row seeks the player straight to that moment. Long videos collapse to the top moments with a one-click "show all timestamps." You stop scrubbing through two hours to find one quote. 💬 AI CHAT ABOUT THE VIDEO Ask the video anything: "What did they say about pricing?" "Summarize the part after 15:00." "List every company mentioned." "What did I miss?" Every answer is grounded in the video's actual transcript, so it cannot invent things the speaker never said. 👥 AUDIENCE REACTION Summario summarizes the comment section into a verdict with a positive / mixed / negative percentage breakdown. You learn whether the tutorial actually worked for people, or whether the top comment is a correction, without scrolling through a thousand replies. 🌍 SUMMARIES IN 70+ LANGUAGES Watch in one language and read the summary in another. Summario generates summaries in over 70 languages — including Spanish, German, French, Portuguese, Italian, Hindi, Arabic, Chinese, Japanese, Korean, Turkish, Polish, Vietnamese, and Indonesian — regardless of the video's original language. Set it once in settings, or leave it on Auto to follow the video. 📝 TURN VIDEOS INTO NOTES — NOTION & OBSIDIAN EXPORT (Pro) Select any text on a YouTube watch page and press Cmd+Shift+H (Ctrl+Shift+H) to save it as a Highlight, or save any key takeaway with one click.

A: Install Summario, open the video, and click "Summarize" in the sidebar widget. A TL;DR and key points appear within seconds, followed by the full YouTube summary with timestamps. You do not need to copy the URL, open another site, or paste a transcript anywhere. Q: Can AI summarize a YouTube video accurately? A: Yes, when it works from the real transcript rather than guessing from the title. Summario reads the video's actual transcript and passes it to state-of-the-art AI models, so takeaways trace back to something that was genuinely said. Accuracy is high for spoken-word content — podcasts, lectures, interviews, news, tutorials. Music videos and content without dialogue will not produce a useful summary. Q: Can ChatGPT summarize a YouTube video instead? A: A general chatbot can summarize a video only if you fetch the transcript yourself and paste it in, and it has no access to the player, the timestamps, or the comments. Summario is built for the job: it pulls the transcript automatically, renders the summary inside YouTube, links every section back to the exact moment in the video, and lets you ask follow-up questions without re-pasting anything. Q: Is Summario free? A: Yes. The free tier includes 1 full summary, 3 quick summaries, and 1 AI chat message per day, on videos under 30 minutes, with no credit card. Pro removes every limit, including the video-length limit. Q: What is the longest video Summario can summarize? A: Free accounts are limited to videos under 30 minutes. On Pro there is no length limit for videos that have captions, so 4-hour podcasts and full conference days work. Videos without captions must be transcribed from audio first, and that path supports videos up to 2 hours. Q: What if the video has no captions? A: Summario transcribes the audio automatically using speech-to-text AI, then summarizes the transcription. You do not have to do anything differently — it happens in the same click. Q: Can I get the transcript of a YouTube video? A: Yes. Every video you summarize is saved to your Summario library at app.summario.net with its full transcript, alongside the summary, your highlights, and your chat history for that video. Q: Can I turn a YouTube video into notes? A: Yes. Save any key takeaway with one click, or select text on the watch page and press Cmd+Shift+H (Ctrl+Shift+H) to capture it as a Highlight. Pro users export the collected notes to Notion, Obsidian, PDF, or Markdown, and Cmd+Shift+S (Ctrl+Shift+S) pushes the latest highlight straight to a preferred destination. Q: What languages does Summario support? A: Summaries can be generated in over 70 languages regardless of the video's original language, so you can watch in English and read the summary in Spanish, Hindi, or Japanese. The extension interface itself is available in English, Spanish, German, French, and Italian, with more added regularly. Q: Does Summario work on YouTube Shorts? A: Yes. Summario supports standard YouTube videos, Shorts, and YouTube Music, as long as there is spoken content to summarize. Q: Does Summario work on livestreams? A: Summario summarizes livestream archives once they are available as recorded videos. Real-time summarization during an ongoing stream may be supported in a future update. Q: Can I summarize private or unlisted videos? A: Yes — you can summarize any video you are able to watch on YouTube. If you have access to it, Summario can process it. Q: Can I get video summaries by email or WhatsApp? A: Yes, on Pro. Subscribe to channels in your Summario account and each new video is summarized and delivered automatically to your inbox or WhatsApp. Q: Do I need an account? A: Yes. An account tracks your daily usage and syncs summaries across your devices. Sign up with Google in one click. Q: How does Summario handle my privacy?
