LangPotato

LangPotato is a browser extension that turns YouTube videos into interactive language learning tools, so the time you already spend watching videos can actually improve your language skills.

It works for both beginner and advanced learners, making it easy to get the most out of every video you watch, no matter your level.

Current features include dual-language subtitles and a floating transcript window, helping you follow along and look up what you hear without leaving the page.

More features are on the way, including hover-to-translate, AI-generated quizzes, and AI-powered speaking practice, so you can soon test yourself and practice speaking directly from the videos you enjoy.
