Common questions
What to know before you start
Does Rolko work with every YouTube video?
No. Interactive subtitles and transcript import depend on Chinese captions or transcript data being available through a supported watch or import flow.
Can Rolko import a YouTube transcript?
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.
