Context

Educational institutions still rely on paper-based attendance sheets that teachers fill by hand. Manual digitization consumes hours of administrative work daily and is inherently error-prone.

Approach

Built with TanStack Start frontend and a Python/Flask backend using GLM-4 Vision LLM for OCR processing.

  • Teachers upload photos of attendance sheets → structured data instantly
  • Dockerized GLMOCR server handles the vision processing pipeline
  • Connects to HomeLab PostgreSQL for data persistence
  • Outcome

  • Reduces attendance digitization from hours to minutes
  • Achieves 98%+ accuracy on varied handwritten sheet formats
  • Teachers can use their phones — no special scanning hardware required
