Open Björn

How Björn works

Björn is five small apps that share one record of what you know. A word you save while reading turns up in your cards, a mistake from a letter becomes a two-minute lesson, and using a word in a conversation counts as reviewing it. Björn, the guide, keeps track and tells you what's worth doing today.

For beginners

If you're starting a language from zero, the daily plan strings the apps together for you, one short session at a time. Pick a language to see its course.
