About LangPanda

LangPanda is a browser extension for language learners who want to study while watching shows they already enjoy. It adds instant dictionary lookups to subtitles on Netflix, YouTube, Disney+, and more than 20 other video sites, covering 36 languages.

Clicking any word shows its definition, readings, frequency and other details without leaving the video. Learners can ask for an AI explanation of how a word works in a tricky line, then save that explanation to a flashcard. Its built-in PandaMemory review system uses FSRS-5 scheduling and stores audio, a screenshot and the sentence with each card, or cards can be exported to Anki.

The product is aimed at people who want input from real media rather than textbook sentences. It also includes vocabulary tracking, tone coloring for Mandarin, Cantonese and Japanese pitch accent, and per-language leaderboards. A seven-day free trial is offered before a paid monthly or yearly plan.
