After learning and teaching Arabic for a while, I noticed a need for quality resources for new learners.
Popular classical Arabic textbooks for beginners like the Medina Books and Arabiyyah Bayna Yadaik are completely in Arabic and require a teacher. As for Arabic grammar books in English, most are overwhelming for beginners.
So, Arabic for beginners is a step in the direction of creating easy to use resources for beginners in English.
Learners progress in gradually through simple lessons, quizzes and exercises.
The core content of the course is free. A few additional resources are available when you sign up for Pro.
