Use Rolko on supported YouTube watch pages to explore Chinese subtitles for pinyin and meaning, or import a supported transcript into the web app when captions are available.

Worked example: from a YouTube caption to reusable vocabulary

The page keeps the watch-page lookup, transcript-reading, vocabulary, and review paths in one truthful sequence.

Encounter a supported caption
A YouTube watch page exposes usable Chinese subtitle text in a supported desktop browser.
Inspect the word in context
Use the subtitle word panel for pinyin and meaning without replacing the video context.
Save the useful word
With a signed-in account and a plan that permits new-word saving, mark it Learning or Learned in the shared vocabulary.
Continue in text or review
When a supported transcript is available, read it in the web app; otherwise continue with the same saved word in spaced-repetition review.

Yes, when a supported transcript is available. Paste the YouTube URL into the Rolko web app to import and read it line by line.

Do I need the browser extension?

Install the browser extension for interactive subtitles on supported desktop YouTube watch pages. Transcript reading in the web app does not require the extension.

Can I learn from YouTube on mobile?

Use the Rolko web app on mobile to read Chinese text and supported imported transcripts. The watch-page extension workflow is for desktop.

Is Rolko affiliated with YouTube?

No. Rolko is an independent learning product and is not affiliated with, endorsed by, or operated by YouTube.
