All three major YouTube URL formats work: standard watch URLs (youtube.com/watch?v=...), shortened links (youtu.be/...), and YouTube Shorts (youtube.com/shorts/...). The AI extracts the video transcript, processes it through a two-pass summarization pipeline for long videos, and returns a clean summary with an overview, key points, actionable takeaways, and main topics. For long lectures or podcasts the transcript is chunked and each section is summarized before combining into a coherent final output.

The summary output is always structured the same way: a brief overview paragraph, a numbered list of 5 to 10 key points covering the main content in the order it is discussed, a bullet list of 3 to 5 actionable takeaways you can apply right away, and topic tags for all the main themes and subjects covered in the video. This structured format makes it easy to scan the summary in under a minute and decide whether to watch the full video or use the key points directly in your notes.

Handles Long Videos and Lectures With Multi-Pass Summarization

YouTube lectures, conference talks, and full podcast episodes can run for hours. The summarizer handles any length by automatically chunking the transcript when it exceeds the direct processing limit. Each chunk is summarized independently and then all chunk summaries are combined into a final synthesis pass. This means you get a coherent summary whether the video is 5 minutes or 3 hours long. Most two-hour lectures produce a summary you can read in under 3 minutes.

Getting the Best Results

The summarizer works best with certain types of videos. Understanding what affects summary quality helps you choose the right videos to summarize.

What Types of Videos Work Best

The summarizer requires the video to have captions or auto-generated subtitles available. Educational content, TED Talks, news reports, product reviews, tutorials, interviews, and most professionally produced videos have captions. Music videos, videos with only background music, and videos where the creator has disabled captions will not work. Auto-generated YouTube captions are supported and work well for standard English content.

How Long Videos Are Handled

Videos under about 20 minutes are processed in a single AI pass. Longer videos use a two-pass approach: the transcript is split into sections of roughly 6000 characters each, each section is summarized individually to extract key points, and then all section summaries are combined into a final synthesis. This means even a 3-hour lecture produces a coherent summary that covers all the major topics discussed across the entire video.

Short videos (under 20 min)Single AI pass, faster processing, very detailed summary

Long videos (over 20 min)Two-pass chunked summarization, full coverage of all topics

Very long videos (over 2 hours)Supported but processing takes slightly longer

Understanding the Summary Structure

Every summary follows the same structure: a brief overview, key points, actionable takeaways, and topic tags. The overview captures the main argument or topic in 2 to 4 sentences. Key points are the 5 to 10 most important facts, arguments, or pieces of information presented in the video in the order they appear. Actionable takeaways are 3 to 5 things you can do or apply based on what was covered. Topic tags identify all the main subjects discussed.

When to Use Basic vs. Advanced Model

The Basic model works well for most everyday videos: tutorials, explainers, news reports, casual interviews, and standard educational content. It produces accurate, well-structured summaries at 10 credits per video. The Advanced model is better for dense technical content, academic lectures, complex financial or scientific presentations, and any video where you need a more nuanced and detailed analysis. Use Advanced for your most important videos and Basic for everyday research.

Basic model (10 credits)Tutorials, news, casual interviews, standard educational content, product reviews

Advanced model (50 credits)Academic lectures, technical deep-dives, complex financial or scientific content, research presentations

Note: The summarizer requires the video to have captions or auto-generated subtitles. Videos without captions cannot be summarized.
