Slova Lingua

Turn the videos you already love into your personal language classroom.

Slova Lingua shows dual subtitles for online videos: the original language on top and your target language below. You always understand what is being said while staying immersed in the original audio.

INSTANT WORD LOOKUP
Tap any word in the subtitles to see its translation and hear its pronunciation using your device's built-in text-to-speech. No need to switch apps or break your flow.

SMART PERSONAL DICTIONARY
Save any word to your dictionary with a single tap. Tag words as "Learning" or "Learned" to track your progress. Saved words are automatically highlighted in subtitles across all your videos, so you always know which words you are working on.

WORD REVIEW SLIDER
A flashcard-style review page lets you go through your saved words one by one, hear their pronunciation, and update their learning status at any time.

VIDEO WORD EXPLORER
Browse every unique word that appears in a video's subtitles. Great for previewing vocabulary before watching or doing a deep dive afterwards.

LEARNING STATISTICS
Track your vocabulary growth over time. See how many words you have saved, how many are marked as learned, and how many are still in progress.

DICTIONARY OVERVIEW
View all your saved words in one place with a full summary: total words, learned count, and words currently in progress.

Choose your interface language, subtitle original language, and translation language from the home screen. Customize your learning experience to match your goals.
