Duolingo has been launched 148 new courses, fully AI-generated. Literally anyone can learn languages.

Previously, most of the courses were available only in English. For example, it was impossible to learn Japanese in Spanish — now there is such an opportunity.

This can be used to make a powerful charge for the brain. If you've already mastered a second language, try learning a new one. This will help you learn two non-native languages at once.
