Neural network automatically distributes photos in your gallery into 7 types of documents (in ABBYY FineReader PDF for Mobile 8.0 and higher).

The Neural network works with full-resolution photos. If the Optimise iPhone Storage option is turned on in the iCloud Photo settings, then the Neural network cannot find these photos. In this case, iCloud keeps only previews of pictutes to save space, and the Neural network cannot identify and search among such low-resolution photos.
