I've always eventually removed site blockers, or just had them become a nuisance that I reflexively dismiss before getting to distracting sites.

I built an AI app that turns any study material into a gamified learning journey Hi everyone! After several months of development, I'm excited to finally launch my project: Odyssa. The idea came from my frustration with reading long PDFs, taking notes manually, and forgetting what I'd learned. Instead of just summarizing content, Odyssa transforms your study material into a complete gamified learning journey powered by AI. You can upload PDFs, documents, and other learni
