About Qfza
Qfza (قفزة, "jump") searches the transcript of a public YouTube video for an exact phrase and tells you the moment that phrase was actually said — so you can jump straight to it instead of scrubbing.
The problem it solves
Everyone has watched a long video knowing the answer is in there somewhere. Rewinding to re-listen takes minutes; the whole reason people use captions or transcripts is that the words exist but finding them costs time.
Qfza turns that into a search box. Paste a YouTube link, type the phrase, and you get a list of timestamps with the matching line of text underneath. Click one and the player jumps to it and plays.
How it works
- You paste a link to a public YouTube video.
- You type the phrase or word you are looking for.
- Qfza reads the video's transcript and returns every match, in order, with its timestamp.
That is the whole product. There is no account required to search, no AI rewriting your phrase into something else, and no summary in place of the video.
What it does not do
- It is not a video summariser. You get the real transcript matches, not a paraphrase.
- It does not fuzzy-match. Searching for a word the speaker never said returns nothing, which is the honest answer.
- It does not bypass anything. If a video has captions disabled, there is no transcript to search and no result to find. Qfza works with the accessibility data that already exists.
- It does not download or re-host video. You keep watching on YouTube.
Who it is for
- Students and researchers pulling quotes out of lectures and interviews.
- Anyone verifying something they half-remembered hearing in a long video.
- Creators checking how their own video was transcribed.
- People who read faster than they can scrub.
Built as a small, honest tool
Qfza does one thing and shows its work: the timestamp, the matched line, and the link back to the video. If a search returns nothing, it says so rather than inventing a nearby match.
