When Your AI Tool Can't Read a YouTube Video

NotebookLM, ChatGPT, and Gemini all hit the same wall on certain YouTube videos. Here's why, and how to get a transcript and summary anyway.

NotebookLM, ChatGPT, and Gemini don't watch or listen to a YouTube video when you paste in a link. They read the caption track YouTube generated or the uploader provided. No caption track, no transcript — the tool has nothing to work with, no matter how the error is worded.

That single point of failure explains most of the rejections people hit: videos with captions disabled by the uploader, videos too new for auto-captions to exist yet, videos in a language YouTube doesn't auto-caption well, and private or age-restricted videos the tool can't open at all.

YouTLDR takes a different path: it transcribes the actual audio (Whisper large-v3 class) for videos up to 5 hours long in 125+ languages, so it doesn't depend on a caption track existing in the first place. Pick the specific error you hit below, or jump straight to the fix.
