Learn a language from content you actually enjoy.
Paste a YouTube video or an article. Click the words you don't know. They become Cards you practice until they stick.
No signup. The demo reader is the real thing — click around.
👆 Click a word — first tap gives the meaning, saving makes a Card.
Watch. Click. Practice. That's the app.
No lessons, no courses, no cartoon owl guilt. A workspace built around one loop that works.
Bring anything.
YouTube videos, articles, pasted text, subtitle files. If you can watch or read it, you can learn from it.
Tap a word. Keep reading.
Instant translation in context — no tab-switching, no flow-breaking. AI explanations exist too, but only when you ask.
↑ You already did this in the live demo above.
Practice what you clicked.
Flashcards, typing, listening — spaced so each Card comes back right before you'd forget it.
Save words in the demo above and they show up here.
the real Flashcards surface — keyboard included
Watch video the way power users do.
Everything you bolt onto YouTube with three extensions — built in, synced to your Cards.
▶ Press Play — the spoken word lights up as you hear it. Click any word to hear just that word. Saving words: hero demo ↑
Hear it. Don't just read it.
Sentence audio cycles target → native → target, hands-free. Train your ears and mouth, not just your eyes.
In the app: Passive Loop replays material you've already studied — familiar audio, not noise. Shadowing mode adds loop + slow-down for mouth practice.

Built for serious learners.
Audio Drill
Hands-free sentence audio. Repeat, slow down, shadow — eyes-free practice for commutes. Try it ↑
Cards with full context
Every Card keeps its sentence, source, and timestamp. You never study a word floating in space.

Lookups are instant and free. AI explains grammar and nuance on demand — it never spams every click.
Your data, portable
Export your Cards to Anki or CSV anytime. Free. Your vocabulary is yours.
One workspace, everywhere
Web, mobile app with share-sheet import, and a browser extension — same Cards, same progress. See mobile ↑
Calm and private
No mascots, no guilt streaks, no selling your reading habits. A quiet tool that respects your focus.
No magic. Mechanisms.
No fluency promises, no "learn like a native". Every feature maps to a learning mechanism with real evidence behind it.
Comprehensible input
You acquire language fastest from material you mostly understand — not from grammar tables, not from incomprehensible native noise.
In the app: your own content, with known-word signals and an honest "too hard for now" state.
Context-rich vocabulary
Words stick when learned inside real sentences you care about — not as isolated dictionary pairs.
In the app: every Card keeps its sentence, source, and timestamp forever.
Retrieval practice
Actively recalling a word beats re-reading it. Recognition, listening, typing, and production are different skills.
In the app: Practice tracks each skill separately — recognizing a word isn't the same as producing it.
Spaced repetition
Memory consolidates when practice returns right before you'd forget — not in one cram session.
In the app: every Card gets a nextPracticeAt; Learn surfaces what's Ready today.
Sentence-level listening & shadowing
Ears and mouth train on whole sentences — rhythm, liaison, speed — not word-by-word beeps.
In the app: Audio Drill cycles target ↔ native audio with repeat, slow-down, and hands-free control. Passive Loop replays only material you've already studied.
Small daily output
A few sentences produced from memory each day turn passive knowledge into usable language.
In the app: a daily 5-sentence habit — completion counts, perfection doesn't.
We name mechanisms, not miracles: comprehensible input, retrieval practice, spaced repetition, and sentence-level listening are among the most consistently supported ideas in language-learning research. What we don't do: promise fluency dates, guarantee CEFR levels, or pretend one method fits everyone.
The best parts of your current stack. One tool.
We use these apps daily. We built what we wished they were.
