How to download the transcripts of a whole YouTube channel or playlist (without an API key)

A channel's back catalogue is hours of expert talk that search engines and AI tools never see. Turning it into
text makes it searchable, quotable and ready for an AI knowledge base, show notes or a newsletter. Copying
captions one video at a time does not scale, and the official API does not hand out other people's captions.

This guide gets you the transcript of every video in a channel, playlist or search, as clean text with
timestamps, for $2.50 per 1,000 videos.

What you get

One row per video:

Field Example
Title, channel, link the video's details
Published, length, views when, how long, how popular
Transcript the full text
Segments each caption line with its start time, for quoting or jumping to the moment
Caption language, auto-generated which track was used, and whether it was typed by a person
Word count 487 for a three-and-a-half-minute music video

Videos without captions are listed in the run summary and are not charged.

Step 1: open the tool

Go to YouTube Transcript Scraper and click Try for free.
No Apify account? Create one free; no card needed. The free plan returns
up to 100 transcripts per run.

Step 2: paste a channel, playlist or videos

{
  "videos": ["https://www.youtube.com/@YourChannel"],
  "maxVideosPerSource": 50,
  "languages": ["en"]
}
Enter fullscreen mode Exit fullscreen mode

Use a playlist link, single video links or searchQueries the same way. Ask for another language with
translateTo.

Step 3: run and export

Click Start. A single video comes back in about a second. Export as JSON for an AI pipeline, or as CSV or
Excel for reading.

New videos only, every week

Add "onlyNew": true, "monitorName": "my-channel" and schedule it weekly: each run returns only the videos
earlier runs did not deliver. A ready n8n workflow
puts them in a Google Sheet every Friday.

Ideas

  • Feed a channel into a retrieval (RAG) knowledge base and answer questions with sources and timestamps.
  • Turn talks into blog posts, show notes or newsletter quotes.
  • Track what competitors and creators say about your product across their videos.
