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 (ZhipuAI) for OCR processing. Teachers upload photos of attendance sheets and receive structured data instantly — no manual transcription. 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.
