How to search inside a YouTube video's transcript

You remember a speaker saying a number, a name, or a specific phrase, but not when. Scrubbing a 90-minute video to find it can take ten minutes. Searching the transcript takes seconds.

Method 1: YouTube's transcript plus browser search (free)

1. Open the video on a computer.
2. In the description, click Show transcript (YouTube Help).
3. Press Ctrl+F (Windows) or Cmd+F (Mac) and type the word.
4. Click the matching line to jump to that moment.

This works on "any video that has captions". The downside: browser search also matches comments and the rest of the page, and the transcript panel is narrow, so long transcripts are awkward to scan.

Method 2: sum.video's transcript tab

Open the video on sum.video, or click Summarize in the Chrome extension. Next to the summary there is a transcript tab:

• search only the transcript, not the page
• click any line to jump to that moment in the player
• copy the exact wording for notes or citations

You also get a summary with timestamps, which often answers the question before you search.

Method 3: ask the chat

If you are not sure of the exact word, ask the chat on the summary page: "When do they talk about pricing?" or "What did the guest say about hiring?". The answer comes from the transcript, and you can then search for a phrase from it to find the moment.

Search tips

• Search for the rare word. "Kubernetes" finds the moment faster than "the deployment thing".
• Try part of a name. Automatic captions often mishear names, so search "Okon" rather than "Okonkwo".
• Search for numbers both ways. "15" and "fifteen" may both appear.
• Use nearby words if the key term is jargon the captions got wrong.

YouTube notes that automatic captions struggle with poor sound quality and overlapping speakers (YouTube Help). If search finds nothing, the word may simply have been transcribed differently.

Common uses

• Quotes: find and copy the exact sentence for an article or paper.
• Fact-checking: check what a speaker actually said before you share a clip.
• Studying: find every place a lecturer mentions a term. See summarize YouTube lectures for studying.
• Livestreams: find the announcement in a three-hour replay. See summarize livestream replays.

Limits

sum.video searches the transcript of one video at a time; it does not search across your whole library. Videos without captions cannot be searched.
