Hey everyone! 👋 I built this tool because I personally use Obsidian for my math notes, and typing LaTeX on a mobile keyboard is honestly a nightmare. I tried existing OCR apps, but I hated that they required an internet connection (privacy risks) or expensive subscriptions. The Challenge: I wanted to see if I could bring desktop-class accuracy to a phone without the cloud. Porting GOT-OCR 2.0 via llama.cpp to Android was a huge technical hurdle—especially managing memory on 8GB devices like my Pixel 7! It's still in "scrappy beta," but it works. I'm actively looking for feedback on performance and accuracy. Happy to answer any questions about the tech stack (NDK/JNI) or the struggle of on-device AI! 🚀
