Summarize any type of YouTube video and of any size in under 30 seconds for free, no account required.

Paste a YouTube video URL into YouTube Summary and click Summarize. The tool extracts available English subtitles and uses AI to identify the main ideas and key points. Read the result on a public summary page instead of watching the entire video first.

Yes. YouTube Summary is free to use, with no account, subscription, or payment required to generate a summary. Temporary request limits can apply to keep the service available.

No. YouTube Summary runs in your web browser on desktop or mobile. Open the website and paste a YouTube link. There is no extension or software to install.

Yes. YouTube Summary can process long videos, including multi-hour lectures, interviews, and podcasts, by splitting long transcripts into smaller parts and combining the results. Available English subtitles are required, and processing time depends on the transcript and service availability.

YouTube Summary accepts regular YouTube video links, youtu.be links, Shorts links, live replay links, and video IDs. The video must be accessible and have English subtitles available to the extractor. A supported link format alone does not guarantee that subtitles can be retrieved.

No. YouTube Summary works from subtitles rather than transcribing the video audio or analyzing its images. If the required subtitles are missing or cannot be retrieved, it cannot generate a summary. Information shown only on screen may not appear in the result.

Summaries are written in English. The current extractor requests English subtitles, including English automatic captions when available. A video spoken in another language can only be processed if an English subtitle track is available to the extractor; support for every language is not guaranteed.

An existing summary can open immediately. A new summary requires subtitle extraction and AI processing, so the time varies with transcript length, YouTube access, and service load. The progress indicator shows the current processing stage.

Accuracy depends on the subtitles and the AI output. YouTube Summary categorizes videos and uses topic-specific prompts to extract relevant points, but summaries can omit context or contain mistakes. Check important details against the original video or transcript.

Yes. Use the separate YouTube transcript extractor to retrieve available subtitle text rather than an AI summary. The video must have subtitles that the service can access; the tool does not create a transcript from audio when captions are missing.

Yes. Each completed summary has a public URL you can bookmark or share by email, message, or social media. You can also search the community history for existing video summaries. Generated summaries are public, so do not treat a summary link as private.
