Overview

YouTube Transcript fetches caption-based transcript segments and plain text for a public YouTube video URL or 11-character video ID when captions are available. Use it to turn one video into text for summaries, quote pulls, clip notes, repurposing briefs, or timestamped research.

Use cases

  • Convert available YouTube captions into timestamped transcript segments and plain text.
  • Pull wording, hooks, claims, examples, or structure from one public video for review.
  • Check returned language and caption tracks before summary, clip, or comment analysis.

Input tips

  • Provide a public YouTube video URL, Short URL, or 11-character video ID.
  • Leave language blank for the default caption track unless you need a specific code such as en or en-US.
  • Use YouTube Video Details first when you need video context or caption-track availability.
  • If a requested language is unavailable, retry without language to request the default track.

Expected output

The AI Tool returns availability status, source video ID or URL, requested language when provided, returned language when available, transcript segments, plain transcript text, caption tracks, unavailable-language or not-found flags, normalization notes, additional recovered fields, and cost metadata. Segments can include spoken text, start and end times in milliseconds, formatted start time, and recovered per-segment fields when returned.

Caveats

  • Captions must be available; some public videos return no transcript.
  • A requested language can be unavailable even when another caption track exists.
  • Segment timing, wording, and language can vary by caption source.
  • Verify important quotations against the video before publishing or citing them.
