Before you start.

A few things to know about captions, collections, and your downloads.

What if a video has no captions?

YouTube Video Transcript retrieves existing caption tracks; it does not transcribe audio from scratch. Accuracy depends on the manual or automatic captions YouTube supplies. If no transcript can be fetched, you are not charged for it; bulk jobs refund that reservation. You can still collect comments separately when comments are available.

How much can I collect in one job?

Website jobs support up to 5,000 videos. Channel collections cover long-form uploads, not Shorts. Transcript jobs must fit your available credits; comments collections stop at the credit limit you set. Bulk transcript jobs created through the API or MCP require a paid plan and have separate per-plan limits.

Does ‘all available’ include replies too?

Replies are optional: turn on Include replies to collect them alongside the top-level comments. All available means continuing through the comments YouTube makes available until the collection finishes or your credit limit is reached. Reply pages use the same budget. If the limit is reached first, the results collected so far are saved.

Can I close the browser while a collection runs?

Yes. Once the job appears in History, transcript and comments collections run on the server, not in your tab. You can close the browser and return to History with the same account to check progress, cancel, or download saved results. Download your files before the job's 100-day retention period ends.

Which files will I get?

Transcripts export as TXT, SRT, JSON, CSV, or Markdown in the website; DOCX is also available through the API. Bulk transcript downloads bundle the files into a ZIP, with optional comment samples as separate JSON files. Standalone comments collections include JSON and CSV in one ZIP. The comments preview beside a single transcript downloads as TXT.

Do I need to sign in?

You can preview one video's transcript without an account. Sign in with Google to download files, search, fetch video details or comments, and run collections. Your free account includes 30 credits every 30 days, with no credit card required. Those credits share one balance across the website, API, and MCP.
