LangPanda
LangPanda is a browser extension for learning languages from streaming video with instant subtitle lookup, flashcards, vocabulary tracking, and SRS for 36 languages.
Overview
LangPanda is a language-learning browser extension and companion study system built around watching video content. It lets learners click subtitle words for instant definitions, audio, readings, and context, then save useful items into flashcards or review them later in PandaMemory or Anki.
The product is designed for immersive study across 36 languages and 20+ supported video sites, including Netflix, YouTube, Disney+, Amazon Prime, Hulu, HBO Max, Bilibili, Viki, and Plex. Its workflow combines subtitle mining, vocabulary tracking, spaced repetition, and a multilingual dictionary so learners can study from shows they already watch.
Features
Contextual AI explanations
Use one-click AI explanations to unpack a word or phrase in the surrounding line and save that explanation to a flashcard.
PandaMemory SRS review
Save words, sentences, audio, and screenshots into PandaMemory, which uses the FSRS-5 algorithm for spaced repetition review.
Anki export and sync
Export cards to Anki with audio and screenshots, or connect AnkiConnect for deck-based workflows.
Vocabulary tracking
Track known, learning, and ignored words, plus vocabulary progress with heatmaps and streaks.
Cross-site study workflow
Use the extension across supported video sites and on mobile for review on the go, with subtitle mining and audio capture included in the paid plans.
Use Cases
Learning from shows you already watch
Watch an episode or clip on a supported streaming site, click unfamiliar subtitle words, and keep moving without switching tabs. This works well for learners who want to turn passive viewing into study time.
Building flashcards from subtitles
Mine sentences, audio, and screenshots from interesting lines to build flashcards from real context. This is useful when you want example-based vocabulary study rather than isolated lists.
Reviewing and exporting study material
Review saved words later in PandaMemory on the web or mobile, or export them to Anki if you prefer an external spaced-repetition deck.
Monitoring vocabulary growth
Track known and learning words, then watch your progress through heatmaps, streaks, and per-episode vocabulary counts. This is a fit for learners who want visible study momentum over time.
