Frequently Asked Questions
What types of YouTube videos can be summarized?
Our AI can summarize virtually any YouTube video with spoken content — tutorials, lectures, podcasts, interviews, reviews, vlogs, and more. Videos with clear audio and speech produce the best results.
How long does it take to generate a summary?
Most summaries are generated in under 30 seconds, regardless of the original video length. Even hour-long lectures are summarized quickly.
Can I summarize videos in languages other than English?
Yes. The AI supports videos in multiple languages and can generate summaries in your preferred language, making it great for multilingual content consumption.
How accurate are the summaries?
Our AI produces highly accurate summaries by analyzing the video's audio transcript and context. Key points, timestamps, and takeaways are extracted with high fidelity to the original content.
Can I download the transcript as a text file?
Yes. After extracting the transcript, you can copy the full text with timestamps using the Copy button. The transcript includes clickable timestamps that link directly to each section of the video, making it easy to paste into documents, notes, or any text editor.
Does it work with auto-generated YouTube captions?
Yes. Our tool works with both manually uploaded subtitles and YouTube's auto-generated captions. Auto-generated captions are available for most YouTube videos in 100+ languages. If a video has no captions at all (auto-generated or manual), the tool will let you know.
What is the difference between the transcript and the summary?
The transcript is the complete word-for-word text of everything said in the video, organized into timestamped segments. The summary is an AI-generated condensed version that extracts only the key points, main arguments, and important takeaways. Use the transcript when you need the full text; use the summary when you want a quick overview.
Is there a video length limit?
There is no strict length limit. Our tool can extract transcripts and generate summaries for videos of any length — from 1-minute clips to 4-hour lectures. Longer videos may take slightly more time to process, but most results are ready within 30 seconds regardless of video duration.
