AI YouTube video transcriber

Captions are the fastest and usually the most accurate source, so TubeTranscript tries them first. If none can be read, the worker downloads the audio and transcribes it with Whisper, which takes longer because it needs the whole file. See YouTube transcript without captions for what to expect.

Want the gist instead of the full text? The YouTube summarizer turns a transcript into a summary with key points linked to the video.

The example above is the start of a real Whisper transcript of a public video without captions, exactly as stored. Whisper turns the speech itself into text, so its mistakes differ from caption mistakes: it can mishear names, technical terms and overlapping speakers, and it does not say who is speaking. Like captions, it also slips on numbers and noisy audio.

Before you quote or publish an AI transcript:

• Check every name, number and quote against the video. SRT, VTT and JSON keep the time of each line, so you can jump to the spot and listen.
• Add speaker names yourself where they matter; the transcript has none.
• Read technical terms and product names twice. They are the words most often misheard.

Videos with captions are not re-transcribed. If a video has readable captions, you get the captions, not a Whisper transcript, because they are faster and usually more accurate. Whisper runs only when no readable captions exist. In the YouTube transcript API, the source field says whether a transcript came from captions or from audio.
