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.

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.

Getting started is easier. The new language setup and Reinforce guidance walk you through choosing a learning language, watching your first video, and saving words to practice.
When you have no viewing history, open Immerse to find curated starter videos for supported languages. If no curated list is available, you can discover videos other learners have watched when available and open suggested YouTube searches with the subtitle filter applied. Copy a video link back into zeroStudy to watch.
Captions now prioritize your learning language when available. Recent videos now show thumbnails, and we fixed issues with recording first views and refreshing the list.
You can resend your verification email from the sign-in screen. Sign-in and registration errors are now clearer and localized.
Vocabulary cleanup now includes previously practiced words that are at least 30 days overdue. Check their practice count and last practice date, then select the words you want to remove. Cleanup deletes the selected words and their practice history.
