It all started at Escuela Internacional de Árabe (eiarabe.com), a fully online academy where we have been teaching Modern Standard Arabic and Moroccan Darija to Spanish-speaking students from all over the world.
Working with students every day, we noticed a pattern: good books were missing, in Spanish, in English and in French. The ones that existed were too academic, too shallow or stuffed with words nobody uses.
So we made them ourselves. We started with '500 words in Modern Standard Arabic' and '500 words in Moroccan' in Spanish. Then verbs and calligraphy. Now we keep adding titles and languages: the mission is big and we are just getting started.
Arabooki is that publisher. Independent, made by teachers, written for real learners.
