Questions? Answers.
Is the YouTube summarizer free?
Yes — paste any public video URL and get a summary free, no signup or credit card. It reads the video's captions, so no download is needed.
How does it summarize a video without watching it?
It reads the video's transcript (captions) and uses AI to pull out a TL;DR, the key points, and the moments worth clipping. The same transcript Nova uses to find your best clips.
What videos work?
Any public video that has captions or auto-generated subtitles — most YouTube videos do. If a video has no captions we'll tell you; you can still upload it to Nova to clip it.
What are the 'moments worth clipping'?
The summarizer flags the specific lines and moments that would make strong short-form clips. Sign up to Nova and it cuts those moments into captioned, vertical, ready-to-post shorts automatically.
Can I turn the summary into clips?
Yes — that's the point. Nova takes the same video and turns its best moments into vertical clips with captions and reframing in minutes. Try it free.
