Since the content disappears after erasing, we have developed a matching app to save notes. The software uses machine vision and image processing algorithms. After finding the border of the book, you can cut and straighten, and you can choose a variety of image enhancement effects. The Elfinbook companion app has powerful document management functions, uses Windows tree file structure for category management, and can be searched, so you can easily find your own paper data. In addition to the powerful local file management functions, most of the common cloud docking can be generated by uploading PDF files to the cloud, such as Evernote, Baidu Cloud, etc., no longer afraid of missing notes, where to go.
