Selecting subtitles is easier. Touch and hold, then drag the handles to choose the words or phrases you want to look up and mark.
Turn the YouTube videos you already enjoy into a language-learning routine. zeroStudy brings interactive subtitles, vocabulary capture, and spaced repetition together, so watching, understanding, and remembering flow in one place.
LEARN WITH YOUTUBE
• Paste a YouTube link and watch without leaving zeroStudy.
• Follow interactive subtitles as the video plays.
• Select a word or phrase to understand and save it in context.
• Continue recently watched videos and track your daily immersion progress.
REMEMBER WITH REINFORCE
• Review vocabulary with spaced repetition at the right time.
• Use active recall to build durable memory.
• Hear pronunciation and revisit the original sentence.
• Add your own words and phrases manually, with optional AI Auto Fill.
• Track your streak, retention, and learning progress.
KEEP YOUR LEARNING CONNECTED
Your vocabulary and progress stay synced across zeroStudy. The optional Chrome extension gives you another way to collect vocabulary while watching on desktop, but it is not required to use the iPhone app.
Watch what you enjoy. Save what matters. Reinforce what you want to remember.
Ratings & Reviews

Selecting subtitle ranges is now more convenient.
Previously, you used the left and right expansion buttons to choose what to look up. In Immerse, you can now touch and hold the subtitle below the video, drag the selection handles to adjust the range, then tap Look up. The existing expansion buttons remain available.
