Building an AI-Powered Language Learning Platform: Lessons We Learned

When we started building Mocko.ai, we weren't trying to create another language learning app. We wanted to solve a problem we kept seeing among language exam candidates: people were spending countless hours practicing but still had no idea whether they were actually improving.

Most preparation platforms rely on static exercises and answer keys. They tell you whether an answer is right or wrong, but they rarely explain why. They also struggle to adapt to each learner's individual strengths and weaknesses.

With the rapid evolution of large language models (LLMs), we saw an opportunity to build something different.

In this article, I'd like to share some of the lessons we learned while building an AI-powered platform for language exam preparation.
