I took home 𝘀𝗲𝗰𝗼𝗻𝗱 𝗽𝗿𝗶𝘇𝗲 in the 𝗜𝗠𝗣𝗔𝗖𝗧 𝘁𝗼 𝗩𝗶𝗲𝘁𝗻𝗮𝗺 track at the Codex Hackathon in HCMC this weekend. I competed as 𝗧𝗮𝘀𝘀-𝗠𝗶𝗻𝗱𝗹𝗼𝗼𝗽. Technically, I entered solo, but my real team had four members: Codex, Claude, Gemini, and me 😆 . The whole weekend became a real stress test: how far can one developer go in a hackathon timeline with the right AI agents, sharp product focus, and a lot of caffeine? The project is called 𝗠𝗶𝗻𝗱𝗹𝗼𝗼𝗽. The thesis is simple: Vietnam scrolls for hours every day. Most learning apps try to fight that habit by asking people to leave Facebook, TikTok, or Reels and open a separate "study" app. 𝗠𝗶𝗻𝗱𝗹𝗼𝗼𝗽 𝘁𝗮𝗸𝗲𝘀 𝗮 𝗱𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝘁 𝗮𝗽𝗽𝗿𝗼𝗮𝗰𝗵. Instead of fighting the scroll, it 𝗶𝗻𝘁𝗲𝗿𝗰𝗲𝗽𝘁𝘀 it. Mindloop turns your saved articles, notes, and technical content into personalized flashcards, then injects those cards directly into your Facebook feed as you scroll. It hides distractions like ads, suggested posts, irrelevant groups, and low-value reels, then replaces part of that attention sink with active recall. The goal is not to shame people into studying harder. The goal is to lower the activation energy until learning fits into habits people already have. For Vietnamese workers, especially in tech, English and technical fluency can be a serious career multiplier. But after long commutes, 6-day work weeks, and constant context switching, the problem is often not motivation. It is friction. 𝗠𝗶𝗻𝗱𝗹𝗼𝗼𝗽 𝗶𝘀 𝗺𝘆 𝗮𝘁𝘁𝗲𝗺𝗽𝘁 𝘁𝗼 𝗿𝗲𝗱𝘂𝗰𝗲 𝘁𝗵𝗮𝘁 𝗳𝗿𝗶𝗰𝘁𝗶𝗼𝗻. Thanks to Codex Community Vietnam , especially An Nguyen , for organizing the hackathon, and to OpenAI and Tasco JSC for sponsoring a space to build for real problems in Vietnam.
