LangPanda turns subtitles on Netflix and YouTube into clickable vocabulary lookups and flashcards.
Grounded in available product and source data
No textbook phrase like 'the pen is on the table' actually comes up in real conversation, yet that's still how most language apps teach. LangPanda is built to learn a language from Netflix and YouTube instead, turning the subtitles of a show a person would watch anyway into clickable vocabulary.
Clicking a word mid-scene brings up a full dictionary entry — definition, reading, frequency rank, and pitch accent or tone marking — without breaking the flow of the show, and an AI Explanation feature goes further on request, explaining exactly how a word functions in that specific line rather than giving only its generic dictionary meaning. Sentence mining then captures the audio, a screenshot, and the surrounding sentence automatically, turning a moment from the show directly into a flashcard rather than requiring it to be typed out from memory later.
Review runs on PandaMemory, a spaced-repetition system built on the FSRS-5 scheduling algorithm and synced across web, iOS, and Android, or exportable straight to an existing Anki deck for anyone who already has one. Tonal and pitch-accent languages get specific visual support too — color-coded tones for Mandarin and Cantonese, and pitch-accent dots for Japanese, rendered inline with the word itself rather than requiring a separate reference.
The underlying approach is framed explicitly as comprehensible input, a concept the site attributes to linguist Stephen Krashen, positioned against textbook-style grammar drilling. 36 languages are supported with native dictionaries, each paired with real show recommendations in that language, and the tool works across Netflix, YouTube, Disney+, Amazon Prime, and 20 other video sites.
No — clicking a word brings up its definition, reading, and frequency rank inline, and hovering to pause is optional rather than required, so the lookup doesn't have to interrupt watching.
That's specifically what AI Explanation is for — on request, it explains the word's nuance in that exact line of dialogue rather than just returning the generic dictionary meaning, and the explanation can be saved directly to a flashcard.
No — captured flashcards can be exported directly to Anki with AnkiConnect support, so an existing deck can keep growing rather than being replaced by a separate review system.
No — tone and pitch-accent rendering is built in specifically for Mandarin, Cantonese, and Japanese, with color-coded tones and pitch-accent dots shown inline, alongside support for scripts like Korean, Thai, and Arabic among the 36 supported languages.
The site doesn't frame it that way — the underlying comprehensible-input approach is positioned as an alternative to textbook grammar drilling generally, built around watching a show a person already wants to watch rather than requiring existing fluency first.
