Frequently Asked Questions

Everything you need to know about YouTube subtitle tracks, API rate limits, and caption formats.

How do I extract a transcript from a YouTube video for free?

Paste any valid YouTube video URL, YouTube Shorts link, or 11-character Video ID into our online extractor tool above and click 'Extract Transcript'. The tool automatically fetches and parses the official or auto-generated caption track into timestamped segments.

What export formats are supported for YouTube transcripts?

You can export YouTube transcripts as Plain Text (.txt), SubRip Subtitle (.srt), WebVTT (.vtt), or raw JSON (.json). You can also copy pre-formatted AI prompts designed for Google Gemini, Claude, or ChatGPT.

Can I extract YouTube transcripts programmatically via API?

Yes, send a POST request to /api/transcript with a JSON body containing {'url': 'https://www.youtube.com/watch?v=VIDEO_ID'}. The API returns an array of timestamped segments, full merged text, and total segment count.

Why does transcript extraction fail for some YouTube videos?

Transcript extraction requires the YouTube video to have accessible captions (either human-uploaded or auto-generated by YouTube). Videos with disabled captions, private videos, or newly uploaded videos without processed subtitles will return an error.

How do I format YouTube transcripts for AI viral moment scoring?

Our tool includes a dedicated 'AI Prompt Ready' tab. It formats the full transcript into timestamped chunks with a structured system prompt so LLMs like ChatGPT, Claude, or Gemini can score virality (0-100) and highlight top hooks.

Is this YouTube transcript extractor free to use?

Yes, 100% free with no account or registration required. Developers can also reuse our open-source Next.js API route implementation in their own commercial or open-source projects.
