The Courses of Language Atlas

Have you ever wondered what the best way is to learn a new language?

I have been learning languages for over 20+ years and I was always frustrated with books, courses, and classes that I had tried.

It never really seemed to work for me.

I wanted to learn a language in the most effective and efficient way, and there was nothing out there for me.

So I thought, “why not make something myself?“.

Using my experience and by doing research I created Language Atlas, a platform where people can learn French and Spanish in the most effective and efficient way.

I created free lessons and quizzes so that there would always be a easy and accessible way for people to learn or brush up on their language skills.

However, I also created courses that are much more comprehensive and in-depth.

These courses are easy to follow, clear, and allow you to become fluent in the most effective and efficient way.

The courses of Language Atlas have:

  • 800+ Lessons with audio
  • 800+ Quizzes
  • 10,000 Flashcards with explanations, images, and audio
  • A gamified way of learning a new language
  • A vibrant community (including support from me)

You can register for free and try the French A0/A1 and Spanish A0/A1 Courses for free!

This includes over 60 lessons and quizzes, 500 flashcards that adapt to how you learn, and access to the community (including support from me).
