Everything you need, nothing you don't

Built because every other subtitle downloader sends you to a website to paste a URL. This one works inside your browser, on the video you're already watching.

⇩

In-browser download

No redirect, no copying URLs. A download button appears directly in the popup while you're on any YouTube video page.

🌍

Every language

The popup lists every caption track YouTube provides for that video. Choose the language you want, download instantly.

📄

SRT, VTT, and clean TXT

SRT for subtitle editors. VTT for web video players. TXT strips all timestamps for a clean, readable transcript.

🤖

Auto-generated captions

YouTube's automatic captions work too. If the video has any caption track available, you can download it.

🔒

Session-based, always works

Captions are fetched in your own YouTube session, so YouTube PO Token changes don't break downloads.

🌐

AI translation Pro

Translate any subtitle file to your language automatically. Powered by GLM AI and returned as a ready-to-use SRT file.

📋

One-click copy Pro

Copy the full transcript to clipboard in one click, ready to paste into ChatGPT, Claude, Notion, or any document.

Frequently asked questions

Everything you need to know before installing.

Does this download the video or audio?

No. YouTube Subtitle Downloader downloads only subtitle and caption files (SRT, VTT, TXT). Captions are user-permitted text data. This extension does not download or circumvent any video or audio content.

Why does it work when other tools break?

Most web-based tools paste-and-fetch caption data through their own servers, which break when YouTube changes its PO Token requirements. This extension fetches captions inside your own authenticated YouTube session in Chrome, so it keeps working as long as you can watch the video.

What if a video has no subtitles?

If YouTube has no caption tracks available for a video (not even auto-generated), the popup will show a "No subtitles available" message. There is nothing to download because YouTube itself has nothing to provide.

Is this affiliated with YouTube or Google?

No. YouTube Subtitle Downloader is an independent Chrome extension by Peak Productivity. It is not affiliated with, endorsed by, or connected to YouTube or Google in any way.

What does Pro AI translation cost to run?

Pro translation runs on GLM AI via our backend. The $5/month or $39/year Pro subscription covers this server cost. Free users cannot access translation.

Can I get a refund?

Yes. Within 30 days of purchase, email support@peakproductivity.online and we will refund you, no questions asked.

What permissions does the extension need and why?

storage: save your settings, daily quota counter, and license. activeTab and scripting: read the YouTube page's caption track list when you click the extension icon. downloads: save the subtitle file to your Downloads folder. youtube.com host permission: access caption data on YouTube pages. peakproductivity.online: license verification and Pro translate API.

Does my subtitle data get sent to your servers?

Free downloads are entirely local. For Pro AI translation, the subtitle text is sent to our server so GLM AI can translate it. No video content, no personal data, only the subtitle text you choose to translate.
