How do I summarize a video with AI?

Upload the video file on this page, complete the security check, and select Summarize video. The AI listens to the speech and returns a short summary with a list of key points.

Can I summarize a YouTube video from its link?

Not on this page, which takes video files only. To start from a link, paste it into the YouTube Summary Generator.

Which video formats and sizes work?

MP4, WebM, OGG, MOV, AVI, and MKV files up to 50 MB, one file at a time. A larger file is turned away before it uploads, so pull out the audio first if yours is over the limit.

Does it summarize what is shown on screen?

Not reliably. It works from what is said, so text on slides, charts, and visual demos may be missing unless the speaker says them aloud. A silent screen recording gives it little to summarize.

Does the summary have timestamps or a length setting?

No to both. You get one summary and one list of key points. For the full wording of the video, use Video to text.

요약의 정확도는 어느 정도인가요?

It depends mostly on the audio. Clear speech from one person at a time gives the best result, while music, echo, and overlapping voices lead to gaps. Check names, numbers, and quotes against the video before you use them.

Is the video summarizer free?

Yes. It is free and needs no account.

Are my uploaded videos stored?

Uploads are deleted after processing. Upload only videos you own or have permission to use.

Why did my video fail to summarize?

The file may be damaged or contain no clear speech. Check that it plays with audible speech, then try again. If processing times out, try a shorter clip.

What the video summarizer does

It listens to the speech in your video and writes a short summary with a list of key points. It works from what is said, so on-screen text and visuals may be left out. A silent screen recording or a music video gives it little to work with.

Upload one file at a time. The summary appears next to the video player. Copy it, or download it as a .txt file that includes the key points.

Videos that summarize well

Recordings where people explain something out loud work best.

Lectures and recorded classes
Webinars, talks, and conference sessions
Meeting recordings with one speaker at a time
Interviews and tutorials with a narrator

Results get worse with loud background music, a distant microphone, or several people talking at once. Slide-only videos, silent demos, and music videos have little speech to summarize.

Video over 50 MB? Pull out the audio

The limit is on file size. If your video is bigger, save only its sound. Run it through the MP4 to MP3 converter, which takes video files up to 500 MB, then upload the MP3 to the podcast summarizer. It accepts audio up to 50 MB and returns a summary and a transcript.

Starting from a MOV or MKV file? Use the MOV to MP3 or MKV to MP3 converter instead.

Check a summary before you rely on it

A summary leaves things out by design, and the AI can mishear a word. Before you quote it or act on it, check the names, numbers, and dates against the video. If a point matters, find that moment in the video and watch it.
