YouTube video summarizer

Find out what a video actually says before you spend twenty minutes on it — a short summary, the concrete points, and who it is worth watching for.

Reads the video's captions and summarises what is actually said. One free summary, then one more with a free account.

What a good video summary contains

Not a description of the video — a compression of it. The claims made, the steps shown, the numbers cited. If a summary could have been written from the title alone, it tells you nothing you did not already know from the search result.

When to summarise and when to read the transcript

  • Summarise when you are deciding whether to watch, or need the gist of something a colleague sent you.
  • Read the transcript when you need an exact quote, a specific timestamp, or the wording someone used.

Why the captions matter

Every summary here is built from the caption track, so it inherits its quality. Clear speech summarises cleanly; heavy jargon, several speakers talking over each other, or a strong accent will show up as vagueness in the result. When the summary feels thin, the transcript usually explains why.

The comments are the other half of the video

PostLink analyses the comments alongside the transcript and surfaces the questions viewers keep asking — your strongest leads for the next video and its title.

Questions

How does the summarizer work?

It reads the video captions — the same text a transcript tool returns — and summarises what is said. Nothing is guessed from the title or thumbnail, so the summary reflects the actual content.

Can it summarise a two-hour video?

It reads a long stretch of the transcript and tells you when a video was long enough that the summary comes from the first part. For podcasts and lectures, use the transcript tool and read the section you care about.

Does it work without captions?

No. Summaries are built from spoken text, so a video with captions disabled or no speech returns nothing rather than an invented summary.

How accurate is it?

It is as accurate as the captions underneath. Auto-generated captions handle clear speech well and struggle with names, jargon and crosstalk, so check specifics against the video before quoting them.

Is it free?

One summary without an account and one more after signing up free. Beyond that it runs on a paid plan, because each summary costs both a transcript fetch and model time.
