Just paste in the URL of the YouTube video and click the Search button. It will go out and find all the available closed caption tracks that have been uploaded for that video and display them in the list. Choose one or more of the provided languages, then choose the format of how you want your transcripts. You can either download them as Text Transcripts, SRT, or VTT caption files. If you choose Text Transcripts, you can choose between text in paragraph form or line-by-line, with or without timecode. Then click the Download button and it will save each language as a separate file. It's that easy!
Or if you want to do a word search on a captioned YouTube video, it will return a list of how many instances of the search term is used in the video and provide you with direct links to the points in the video where the search term is used. The search results can also be saved as a text file along with the timecode where the search term appears. No need to watch the whole video to see if it contains the content you're looking for!
