Détecteur de Fautes is an educational and entertaining application that will allow you to test your French language skills.

This application is made for people who want to improve their French language skills, either by self-study or with the help of an instructor.

The official application of the Détecteur de Fautes is divided into four sections.

The first section, "Repérer les Fautes par Catégories," is where you will find the most difficult exercises. In this section, you will have to locate the errors by category, which will be presented in random order.
