AI Video Summarizer: the gist of any video in seconds.
A free AI video summarizer that turns any captioned YouTube video — or a pasted transcript — into a concise summary plus the key takeaways in seconds. Paste a link, get the gist without watching the whole video. Built for creators and teams who triage long videos, podcasts, and webinars before deciding what to clip or repurpose.
Paste a YouTube link or a transcript. The summarizer pulls the captions, reads the whole thing, and gives you a 2–4 sentence summary plus the key takeaways — so you get the gist without watching the full video.
Works with any public YouTube video that has captions. No signup.
Who this is for
Creators and teams triaging long videos, podcasts, and webinars before deciding what to clip; researchers and students who need the gist of a video fast.
The problem this solves
Long videos, podcasts, and webinars take far longer to watch than to act on. Before you can clip or repurpose a recording, you need to know what is actually in it — and scrubbing an hour of footage for the good parts is the most tedious step. The summarizer reads the transcript and hands you the gist plus the key moments in seconds.

Frequently asked
Is the AI video summarizer free?
Yes — completely free, no signup or account required. Paste a YouTube URL or a transcript and you get a summary plus key takeaways instantly.
How does it summarize a YouTube video?
It fetches the video’s captions (the transcript YouTube already generates), reads the full text, and uses AI to produce a faithful 2–4 sentence summary plus 5–8 key takeaways. It never invents facts that are not in the transcript.
Does the video need captions?
Yes. The tool reads a video’s captions, so the YouTube video must have captions or auto-captions enabled (most do). If a video has none, paste the transcript directly instead.
Can I summarize a podcast or webinar?
Yes — if it is on YouTube with captions, paste the URL. Otherwise paste the transcript. Long podcasts and webinars are exactly what this is built for: recordings you want the gist of before clipping.
What is the difference between this and Clipflow itself?
This tool gives you the summary. Clipflow (the full product) takes the same video and turns it into short clips, brand-voice captions, and scheduled multi-platform posts — the whole repurposing pipeline.
