ExamShield AI is a full-stack online exam platform where admins create MCQ exams and students take them under live webcam proctoring. MediaPipe face detection runs in the browser to flag missing or multiple faces, looking away and tab switches, so no video leaves the student’s device. Each session gets a suspicion score and an approve, review or reject recommendation, and answers are graded on the server. Built with React, TypeScript, Tailwind, FastAPI and MongoDB Atlas, and deployed on Vercel and Render.
