“Learn from my own interests?
Game-changing.”
Real language lives in real content
Textbook dialogues are written to be easy. YouTube is the opposite: real people speaking at real speed about things they genuinely care about — cooking, gaming, football, politics, vlogs. That’s the language you actually want to understand, and studies of successful learners agree: massive input of content you enjoy is rocket fuel.
The problem was always the friction: pausing videos, typing words into dictionaries, losing them in notebooks. Björn removes it. Add the channels you love, watch with captions, and save any word or phrase with a tap.
From caption to conversation
Saved words don’t rot in a list. They land in your wordbook, become dynamically generated flashcards, and resurface in your conversations with Björn — so the phrase you heard from a Berlin vlogger on Tuesday is one you’re confidently using yourself by Friday.
That loop — hear it in the wild, capture it, practise it, use it — is how vocabulary actually becomes yours.
Your creators, your curriculum
Subscribe to channels inside Björn, and your language course starts looking like your YouTube home feed — because it is. Learning from content you’d watch anyway is the difference between discipline and momentum: one runs out, the other doesn’t.
YouTube learning is included in the free tier, together with conversations and flashcards. No credit card required.
Learn from creators you love
Any YouTube channel in your target language becomes study material — vlogs, sport, cooking, anything.
One-tap word capture
Save words and phrases straight from captions — no pausing, no dictionary tabs, no lost notebooks.
Words flow into practice
Everything you save becomes flashcards and shows up in your conversations until it’s truly yours.
Motivation that doesn’t run out
Content you’d watch anyway keeps you learning on the days discipline fails.
