Duolingo more than doubled its offerings of language courses to help people learn a second language and become multilingual with the help of generative artificial intelligence.

Following the CEO’s announcement that Duolingo would be ‘AI-first,’ the company is launching 148 new language courses. Duolingo is “more than doubling” the number of courses it has available, a feat it says was only possible because it used generative AI to help create them in “less than a year.”
