Bingy

Bingy is a Chrome extension designed to support language learners by adapting subtitles on Netflix and YouTube to each user's vocabulary level. It enables viewers to learn new words in context while watching shows or videos, offering a personalized approach to language acquisition. The tool addresses the challenge of vocabulary retention by highlighting unknown words and providing real-time translations within the subtitles, making language learning more engaging during entertainment.

One of Bingy's core features is its ability to customize subtitle behavior based on user-defined rules or pre-set modes. Users can set their own rules for how subtitles appear or select from three ready-to-use modes: Chill mode, which translates unknown words inline and switches hard subtitles to the user's native language; Focus mode, which displays both languages side by side for immersion; and Listening mode, which blurs easy subtitles to train listening comprehension. Unknown words are highlighted in yellow, and users can hover over any word to see its translation. As they gain confidence, words can be marked as known with a single click, allowing the tool to track and visualize vocabulary growth over time.

Bingy determines a user's vocabulary level through an initial vocabulary test during setup, estimating known words and refining accuracy as the user continues to watch content. The platform is intended for anyone looking to improve their language skills, including those with specific learning needs, as highlighted by user testimonials mentioning support for dyslexia through multimodal exposure to words.

The extension is free to install and use, and is available exclusively for Chrome browsers on computers. Bingy is developed by a two-person team, and users can contact them via email for feedback or questions. The tool positions itself within the class of language learning aids that enhance streaming experiences by integrating adaptive subtitle technology.
