Idk about the blockchain stuff, but it is semi-featureful since it can extract text from images (I'm assuming its just using Tesseract OCR. At least it could get the text out of this http://www.antigrain.com/research/font_rasterization/msword_...), and I assume audio (but I am having difficulty testing it out). Tbh the formats it accepts as well as the fact that it is available over messenger are huge "selling" points for me and should be way more emphasized on the product page than blockchain and AI.
