Why you have to paste the transcript in
ChatGPT, Claude, and Gemini cannot reliably watch a YouTube video or pull its captions themselves. Handed a bare link, most assistants guess from the title, the description, and whatever comments they can see, which produces an answer that sounds confident and is often wrong. Pasting the real transcript replaces that guess with the video's actual words, so the assistant is answering from something it has actually read.
That is the whole idea behind this page. Paste a YouTube link above, get the transcript, press Copy for AI, and paste the result into whichever assistant you already use. The assistant does the reasoning. This site only gets the accurate transcript onto your clipboard.
What Copy for AI puts on your clipboard
Copy for AI copies the timestamped transcript wrapped in a fixed prompt. It asks for a one paragraph overview, the key points as bullets, and notable quotes each with its timestamp, and it appends the video's title, channel, and URL underneath the transcript so the assistant has context. That is all it does. It does not send the transcript anywhere by itself, it only prepares what lands on your clipboard when you press it.
Five prompts worth trying after you paste
The default Copy for AI prompt covers a general summary. Once the transcript is in the conversation, you can ask for something more specific without pasting it again. Try one of these underneath the pasted transcript, or as a follow up question.
Summary
Summarize this transcript in three sentences, then give me five key points as bullets.
Study notes
Turn this transcript into study notes with headings for each topic and a one line takeaway under each.
Action items
Pull out every action item or recommendation mentioned in this transcript as a checklist.
Quote check with timestamps
Give me the three strongest quotes from this transcript, each with its timestamp so I can verify it against the video.
Translation
Translate this transcript into Spanish, keeping the paragraph breaks and the timestamps.
Handling a very long video
A two hour lecture or a long podcast produces a long transcript, and very long transcripts may need to be pasted in parts rather than all at once. Use the timestamped view to split the transcript at a natural break, paste each part in turn, ask for a summary of that part, then ask for one combined summary once every part has gone in.
What happens to what you paste
The transcript is pulled from YouTube's own caption data and copied to your clipboard entirely in your browser. From there it goes only to whichever assistant you paste it into. This site never sees what you paste and is not part of the conversation you have with ChatGPT, Claude, or anyone else. Transcripts of public videos are cached so they can be served as readable pages in the transcript library, and that is caption data YouTube already publishes, not anything of yours.
