About Slova

Slova turns YouTube & TikTok into your personal language classroom.
Watch content you actually enjoy — and learn the language at the same time.


🎬 SUBTITLES THAT WORK WITH YOU

Dual subtitles overlay directly on YouTube & TikTok.
Original and translation, synced word by word in real time.
Active segment and its translation is always visually highlighted — and each spoken word is highlighted as it plays.

Tap any word for extended translation — synonyms, other uses of the word in the text,
examples from other texts, word definitions (for some languages).
Write your own custom translation alongside the default one.

Customize the subtitle overlay — size, position, style, visibility:
· Turn on/off translation display, translation popup, or auto-show of words being studied
· Configure separate highlighting by word status — new, studying, learned
· Auto-scroll to the active segment so it's always in view
· Choose scroll behavior — always centered, page-by-page (segments scroll automatically
as audio plays), or set custom scroll boundaries
· Or disable auto-scroll entirely


💬 TAP ANY WORD — KNOW IT INSTANTLY

Tap a word and the video pauses automatically.
You see the translation, your own notes, example sentences,
other uses of that word in the video, and Tatoeba context examples.
The word and translation are read aloud — so you hear it, not just see it.

Word popup settings:
· Toggle: show or hide each translation section, and set whether it's open or closed by default
· Text size for each individual translation section
· Audio on tap — 4 levels: word only · word + synonyms/alternatives · with group count
(All audio options can be turned off in settings.)


📖 SAVE WORDS WITH ONE SWIPE

Swipe right → saved as "Already know"
Swipe left → saved as "Studying"

Words marked as "Studying" always appear with their translation
in the subtitles — so you see the meaning every time they come up.


📊 KNOW YOUR WORDS — BEFORE, WHILE, OR AFTER WATCHING

Open any video and see exactly how many words you already know,
are currently learning, or have never seen before.
Browse every word from the video as individual slides —
with translation, context, and audio.

Turn on auto-play mode — slides change and words are read aloud
automatically. Perfect for background listening while you do other things.

Experimental linguistics mode (English and some other languages) — when enabled,
all related word forms are saved together with the word; if you learned "run",
words like "runs" and "running" are automatically added to your dictionary
with the same status


📚 STUDY FROM YOUR DICTIONARY

Same slide experience — but for words from your dictionary, not a specific video.


🗂 YOUR PERSONAL DICTIONARY

All your saved words in one place.
Every word shown with the original sentence from the video
and its translation — so you always understand the word in context,
not just as an isolated term.

Filter by status · search by word
Sort by: date · name · last action · status · number of actions · alphabet · random
Add, edit or delete words manually

🔁 BACKGROUND STUDY MODE

Turn it on and walk away.
Words from your dictionary cycle automatically with audio —
translation, synonyms, explanations, whatever level you set.
Learn while cooking, commuting, or working out.
