Qfza Video Search: Find Words Inside YouTube Videos

Qfza is a video search tool for finding a spoken word or phrase inside a public YouTube video. Paste the video link, search the transcript, and jump to the moment that matches.

Search inside a YouTube video in four steps

1. Open Qfza and paste a link to an individual public YouTube video.
2. Enter a word, phrase, or quote you remember hearing.
3. Review the matching transcript lines and timestamps.
4. Open a match to jump the video to that moment.

Qfza searches the transcript text; it does not need you to scrub through the timeline or watch the full video to find a passage.

Find a moment in a lecture, interview, or tutorial

Use Qfza when you remember what someone said but not where it appeared. Search for a definition in a lecture, a quote in an interview, a step in a tutorial, or a topic discussed in a long video. Each match gives you the surrounding line and a timestamp so you can check the context in the video.

What videos can Qfza search?

Qfza works with public YouTube videos that have a transcript available. If captions or transcript text are unavailable, there is nothing for the search to match. Enter a video URL rather than a channel or playlist URL.
