# Duolingo

**Duolingo** is cited as a brand engineered to capitalize on **micro** [[concept-curiosity-window|curiosity windows]]. It turns brief pockets of [[concept-found-time|found time]] — such as waiting in a grocery line — into language practice via targeted nudges.

It exemplifies the 'micro time gain → simple task' side of [[claim-long-time-gains-enable-deep-exploration]], the counterpoint to the deep, macro-window products like [[entity-coursera|Coursera]] and [[entity-peloton|Peloton]].

**Enrichment context:** canonical at *duolingo.com*; designed for short, gamified sessions in mobile micro-moments — a textbook micro-curiosity-window design.
