Redator AI — ENEM Essay Correction
// PROBLEM
Students often lack fast, objective feedback on ENEM essays; manual grading is slow and inconsistent.
// ARCHITECTURE
React frontend for image upload, FastAPI backend for preprocessing (OpenCV) and Tesseract OCR; LangChain + Gemini evaluates text against ENEM criteria and stores results in PostgreSQL.
// IMPACT
Automated, rubric-based scoring and actionable feedback reduce turnaround time and provide consistent evaluations at scale.
