ClipQuery is a web app (clipquery.com) that lets you ask questions about YouTube videos: it answers from what is actually said, shows the exact moment, and can compare what several videos say in one table.
Watching them one by one works, but it is slow, and you have to remember what each one said. A tool that reads all of them at once is faster: with ClipQuery you pick up to 10 videos, ask one question, and get one comparison table with a column for each video.
Open the video's transcript and search it, or use a tool that does it for you. With ClipQuery you type a question in plain words, and the answer comes with a time chip; tapping the chip opens the video at that exact second.
Use a tool that reads the transcript and writes the summary for you. In ClipQuery you paste a video link and get a summary, clickable chapters and the full transcript with timestamps, and every chapter jumps to its place in the video.
Yes, there are several. ClipQuery is one: you paste a YouTube link, ask a question in plain words, and it answers only from what is said in the video, with a time chip that opens the exact moment.
YouTube shows a basic transcript under each video. A tool like ClipQuery goes further: it gives the full transcript with timestamps, lets you ask questions about it instead of reading it, and exports it to PDF.
