Turn YouTube into your personal language classroom.
Slova lets you watch any YouTube video with dual subtitles — original
language on top, your target language below — so you always understand
what's being said while staying immersed in the original audio.
INSTANT WORD LOOKUP
Tap any word in the subtitles to instantly 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. Words you've saved are
automatically highlighted in subtitles across all your videos — so you
always know which words you're working on.
WORD REVIEW SLIDER
Dedicated 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 after.
LEARNING STATISTICS
Track your vocabulary growth over time. See how many words you've 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.
FLEXIBLE SETTINGS
Choose your interface language, subtitle original language, and
