YouTube Video Summarizer

A real summary built from a video's actual caption track — keyword-scored extraction, not an AI watching the video.

Pulls the video's real captions and picks the highest-signal lines to form a summary. Requires the video to have captions available.

Creator guide

An extractive summary is honest, not a black box

The summary is built by scoring your video's real caption lines by keyword frequency, not by an AI model interpreting the content — you can trust every word came directly from the video.

What this tool does

Extracts the real caption track and keeps the highest keyword-scoring lines, in original spoken order, as a summary.

How to use the result

Use it for a fast overview — it's extractive, not an AI-generated summary.

Data to note

This is an extractive, keyword-frequency summary of the real transcript — explicitly not an AI model that watched or understood the video.

A simple way to use this tool

  1. Use it as a fast overview, not a substitute for watching.
  2. Longer, denser videos produce longer summaries automatically.
  3. Edit the summary into your own words before publishing it anywhere.
FAQ

Common questions

No. It's extractive — we score every real caption line by keyword frequency across the transcript and keep the highest-scoring lines in their original order. No model reads or interprets the video.

The video needs auto-generated or uploaded captions available on YouTube. Very new uploads sometimes don't have auto-captions yet.
