Duolingo is a free app that is designed to help people who want to learn a new language. It has a very attractive UI, fun lessons, and a very comprehensive language database. Now, Duolingo has introduced bots to its application.

These artificial intelligence bots would be able to hold artificial conversations with people. To make matters even more interesting, the bots have been given different personalities.

Text-based chatbots are a little different from the back-and-forth translation, as it's more intuitive for the learner. The personality bots would each react differently to answers and correct people if the need be. 

The bots are primarily aimed at helping people improve their conversational skills and topics of conversation most often have uses in real life, such as ordering food, visiting a tourist attraction, shopping for clothing or catching a cab.

"One of the main reasons people learn languages is to have conversations," wrote Duolingo CEO and co-founder Luis von Ahn in a statement. "Students master vocabulary and comprehension skills with Duolingo, but coming up with things to say in real­-life situations remains daunting. Bots offer a sophisticated and effective answer to that need."

At the moment, this new feature is only available for the Duolingo iPhone app. A version for Android users is expected to be soon.
