How I Won Hacktoberfest: Building StudySnap in One Day 🏆
I won at Hacktoberfest Hack Day Chittagong — and everything, from the idea to the deployed app, happened in a single day at the event.
The idea
When the rulebook landed — campus/study problems only, open-weight models only — I brainstormed around a simple frustration: studying from handwritten notes is painful. That became StudySnap: snap a photo of your notes, get a summary and a quiz.
What I built in ~4 hours
StudySnap turns a photo of handwritten notes or lecture slides into:
- A summary in Bangla or English (toggle)
- An interactive quiz generated strictly from the notes — every question cites the exact note line it came from
- Follow-up Q&A grounded in the same notes
One vision call to Gemma 4 does the heavy lifting: photo in, structured JSON out. Stack: Next.js, Prisma, Supabase, deployed on Vercel. No auth — device-based history, because there was no time for login flows.
The win

What I learned
- Read the rulebook first. Everything flows from the constraints.
- Constraints are a feature. "Campus problems only, open models only" shaped a sharper idea.
- Speed beats perfection. A shipped quiz with source citations beats a perfect plan that never launches.
- Free-tier tools will betray you at the worst moment. Have a fallback ready.
