Overview
Ask questions about any YouTube video and get a short summary. Study with flashcards. Also works on webpages and any file.
SummarizAI is an AI YouTube Summarizer helps you understand YouTube videos — and any webpage — faster with AI-powered summaries, chapters, timestamps, chat, flashcards, quizzes, study notes, and fact checking. Use the in-page panel on YouTube watch pages, or open the Chrome side panel on articles, docs, and other sites for Summary, Chat, and Flashcards. Stop wasting time scrubbing through long videos or rereading dense pages. SummarizAI adds an AI summary experience beside YouTube and a side-panel toolkit for the rest of the web so you can capture key ideas, important moments, and useful takeaways quickly. What SummarizAI can do: • Summarize YouTube videos with AI Generate clear, structured summaries from video transcripts and captions. • Summarize any webpage Open the side panel on HTML pages to extract readable text and get a concise AI summary. Browse previous page summaries in History and reload a saved summary anytime (no re-run required). • Create timestamped chapters See the main sections of a video and jump directly to the moments that matter. • Chat with YouTube videos Ask questions about the video and get answers based on the content. • Chat about the current page Ask grounded questions from the side panel using the readable text of the active tab. • Generate flashcards Turn educational videos, tutorials, lectures, podcasts — and webpage content — into study cards. • Take quizzes Test your understanding with AI-generated quiz questions. • Create study notes Convert long videos into organized notes for learning, research, or review. • Fact check video claims Analyze key claims from a video and review AI-assisted verification. • Customize your summary Choose summary length, format, language, style, and AI persona. Privacy note: webpage text is sent only when you use Summary, Chat, or Flashcards in the side panel. Whether you are watching educational videos, tutorials, interviews, podcasts, documentaries, business content, coding lessons, or reading articles and documentation, SummarizAI helps you save time and understand more. No more endless rewinding. No more missing the main point. No more watching an entire video — or skimming an entire page — just to find one useful idea. SummarizAI brings AI video summaries, YouTube transcript summarization, webpage summarization, AI chat, flashcards, quizzes, study notes, fact checking, timestamped chapters, and side-panel page tools into one simple Chrome extension. Watch less. Read less. Learn more.
