Learn languages from Netflix, YouTube, and real-world texts with dual subtitles and AI
View your target language together with a translation, pause, replay single lines, and jump back to the previous subtitle with a hotkey.
Hover or click any subtitle word to see definitions, part of speech, and pronunciation without leaving the video.
Automatically saves looked-up words and phrases, then quizzes you with the original context to build durable recall.
Bring the same translation and lookup workflow to ebooks, PDFs, articles, and other web pages.

Reach ChatGPT from the menu bar either through the website or natively with your own API key, without leaving what you are doing.
Copy an entire conversation as a clean, readable transcript instead of fighting with selection across the UI.
