A chat assistant reads text. When you paste a YouTube link and ask for the transcript, it can only work with text that is attached to the video or published about it: the captions, if the video has them, or the title and description. It does not play the video and write down what is said.

That works for a short, popular video with clean captions. It stops working in the case people usually ask about: a long podcast, lecture, sermon or meeting recording that has no captions at all.

Why so many long videos have no captions

YouTube's transcript panel only shows captions that exist. YouTube's own help page on automatic captioning lists the usual reasons that automatic captions are missing:

  • the language is not supported by automatic captions
  • the video is too long
  • the sound quality is poor or not recognised as speech
  • the video starts with a long silence
  • several people speak over each other

The creator can also turn captions off, and recent uploads and live stream recordings may not have them yet. In all of these cases there is no text for a chat assistant, or for a caption-copying tool, to read.

Even with captions, a 3-hour video is a lot of text

A three-hour talk holds tens of thousands of words. A chat reply has a practical size limit, so an assistant asked for every word of it tends to shorten, summarise or stop partway. For a transcript you can quote from, you want the whole text with timestamps, not a summary.

The two-step way that works

  1. Get the transcript first. Paste the link into a tool that reads the audio. Our YouTube transcript tool uses the video's captions when they are good and transcribes the audio when there are none. It splits the video into parts of up to ten minutes, writes each part out in full, and joins them in order, with a timestamp at the start of every paragraph. Videos of up to 6 hours are one payment of $5; the first part is free without an account.
  2. Bring the text to the chat. Copy the transcript or download it as TXT, then paste it into ChatGPT, Claude or Gemini with your question: a summary, a list of quotes, show notes. Every job on NoCutoff also has its own chat, so you can ask about the video next to the transcript.

If you need the video's words as subtitles in another language rather than as a document, the YouTube subtitle tool makes an SRT or VTT file, every line on its original timing, also for videos without captions.

Limits worth knowing

Only public and unlisted videos can be read. Private, members-only and age-restricted videos, live streams that are still running and whole playlists are not supported. AI transcription is accurate on clear speech and makes mistakes on noisy audio and overlapping voices, so check names and numbers against the video before you quote them.
