Weird app. Handwriting recognition for file conversation is the worst I've tried. I have terrible handwriting but most apps can find something. The weird part is the AI tool then summarized the same document perfectly. If it can read it and summarize it, why can't it read it and create a nice looking document from it? For that feature, working, I would pay well.

As a student managing tons of PDFs, notes, and assignments, this app has genuinely made my life easier. The AI features are incredibly helpful — I can quickly pull out important points, summarize long documents, and even organize my study material without spending hours. It feels like having a smart assistant for all my academic work. The interface is clean and easy to use, so I didn’t have to struggle to get started. Honestly, it has saved me so much time and effort.
