Free YouTube Transcript Extractor: How to extract and automate captions

Transcripts are essential for AI note-taking, search indexing, video summarization, and language learning. However, extracting clean, timestamped subtitles from YouTube videos can be cumbersome.

In this guide, we cover how to use our free web-based YouTube Transcript Extractor and how developers can automate transcript extraction with our production REST API.

1. Web-based Extractor (No account required)

If you just need captions for a single video, you can use our interactive YouTube Transcript Extractor:

1. Paste any YouTube watch URL (e.g. https://www.youtube.com/watch?v=dQw4w9WgXcQ) or video ID.
2. Complete the quick verification.
3. Instantly view timestamped cues and copy formatted text or download as .txt or .srt files.

This tool is completely free for up to 3 extractions per IP per day and requires no sign-up or credit card.

2. Automating Transcripts at Scale (API)

For AI applications, SaaS platforms, or batch processing pipelines, you need an automated, high-concurrency API rather than manual copy-pasting.

With ytapi, fetching transcripts is as simple as a single HTTP GET request:

curl "https://api.ytapi.dev/v1/transcripts/dQw4w9WgXcQ?lang=en&format=json" \
  -H "Authorization: Bearer yta_YOUR_API_KEY"

Key API Advantages:

• Zero failure billing: You are only billed 1 credit for HTTP 200 successes. Unavailable transcripts or deleted videos cost 0 credits.
• Probe before fetch: Check available subtitle languages for free with GET /v1/transcripts/{id}/languages.
• Multi-language support & translation: Retrieve native auto-generated or manual captions, or translate on-the-fly with ?translate=es.
• Multiple formats: Request format=json, format=srt, format=vtt, or format=text.
