Language Reactor LinguaCap

LinguaCap helps you learn languages through videos you want to watch. Explore YouTube videos with interactive subtitles, look up unfamiliar words, and turn useful phrases into a review habit.

Learn from real speech, context and topics that keep you interested. Whether you are starting out, building confidence or refining your listening skills, LinguaCap lets you study at your own pace.

Learn with videos
Open captioned YouTube videos in LinguaCap and follow along with dual subtitles. See the original text and a translation side by side while the video plays. Caption availability depends on each video.

Understand words in context
Tap a word in the subtitles to view its translation, pronunciation and example sentences without leaving your video.

Review what matters
Save words and phrases to flashcards. Spaced-repetition reviews help you revisit saved vocabulary over time.

Train listening and pronunciation
Use dictation mode to listen to a segment, write what you hear and compare your answer with the subtitles. Replay individual lines, slow down playback and practise shadowing to work on pronunciation, rhythm and intonation.

Study beyond a single video
LinguaCap saves the videos you study with their transcripts, timestamps and vocabulary, so it is easy to continue where you stopped. The built-in browser can also show a dual-subtitle overlay on supported video websites with subtitles.

Build a learning habit
Set daily reminders, keep your streak and make steady progress in short study sessions.

Languages
Use LinguaCap to study English, Spanish, French, German, Italian, Portuguese, Japanese, Korean, Chinese, Russian, Turkish, Arabic and more.
