Script Looper: Learn English

Native YouTube too fast to understand? Memorizing words and grammar won't get you there. The real answer: consistent listening to native speech you can actually understand. And the best source is YouTube - endless, authentic, and free. Script Looper makes it comprehensible. 20+ YEARS OF PROVEN METHOD, BUILT INTO ONE APP The developer knows the struggle firsthand. Even after studying in the U.S. on a government scholarship and serving at an international organization in Switzerland, fast native speech remained a wall. Starting listening practice in his mid-40s, he broke through by training only with real native audio - a method he documented in two published books on English learning (including one by a leading English-education publisher in Korea) and shared with a 50,000-member listening-study community he founded. After years of studying with existing PC browser extensions, he built Script Looper to fix everything they couldn't do: no auto-repeat, poorly segmented subtitles, no way to fix sync issues, and machine-level translations. KEY FEATURES - Loop Any Section Tap once to repeat a subtitle line until you catch every word. Drag to select part of a line - or several lines - and loop exactly what you need. - Speed Control No speech is too fast at 0.75x or 0.5x. Adjust speed even while looping. - AI Context Translation ChatGPT and Gemini generate context-aware translations in your language, displayed line by line under subtitles restructured into natural sentence units. Long videos are divided into 5-minute sections, with completed sections marked so you can pick up where you left off. - Don't Understand? Drag & Ask Words, idioms, even slang you won't find in dictionaries - drag to select anything and tap Ask. Get the meaning in context, nuance, and example sentences instantly, in your language. - Sync Adjustment If subtitles and audio don't match, fix it on the fly in 0.1s or 0.5s steps. Especially useful for auto-generated captions. - Review Quizzes & Study Tracking Everything you've asked about comes back as quizzes. Set a daily goal and track your study time by day and week. NEVER WONDER WHAT TO WATCH Sitcoms, news, talk shows, lectures, kids' content and more - open our curated channel collection (Script Looper YouTube Picks) right from the app. From Friends to TED to CNN, every channel is checked for subtitle quality. PERFECT FOR YOU IF... - Your test scores are fine, but real listening and speaking aren't - You've tried learning with shows or YouTube and gave up - You believe in acquisition through comprehensible input - not memorization When enough comprehensible native speech accumulates, one day your ears open and the words start coming out on their own. Enjoy native YouTube - and get there. Note: Script Looper is a learning tool that works on top of YouTube. Some features require a ChatGPT account (both free and paid accounts are supported).
