Suffering from a scarcity of Arabic scientific content on the Internet, and finding it difficult to obtain Arabic studies and books from reliable sources without spending hours sorting search results? Don't have an account on university digital repositories? You may not pay a download fee for each search. I found you an Arabic alternative that searches in many Arab and foreign universities' repositories open with the support of Google, and the results are direct and from reference sources and complete files for letters, research and books. This is what you will get with the paid version in addition to communicating with the developer from the interface of this application that allows you to download research, with the paid application you will not need to spend more time or money as it provides many alternatives and sources, including books, letters, Word files, and open PowerPoint presentations.
