Practice Languages with an AI WhatsApp Bot
Parlai is a WhatsApp bot powered by AI you can practice languages with
In plain English
Juan Herrera's Parlai is a WhatsApp chatbot you can practice a language with. It can turn your own study material into practice, then ask questions, explain answers, and sketch a study plan, the way a practice partner would. Learners can start free and pay a student-friendly subscription when they want more, because a human partner is not always free to chat. The AI does most of the practice conversation, and taking payment is handled too. Juan still checks quality, helps learners, and shares Parlai in student communities.
