Academic integrity system
Zero Cheating
Evidence across the whole assessment.
A Chrome extension, desktop proctoring app, mobile verification flow, and evidence backend for assignments and exams.
Overview
The product
Zero Cheating connects assignment authorship, exam-environment monitoring, identity verification, and educator review through one evidence model.
Challenge
What had to change
A final answer or exam result rarely explains how it was produced. Reviewers miss authorship changes, device activity, identity context, and the environment around the assessment.
Response
The system built
The system captures observable signals while work happens, processes heavier evidence asynchronously, and organizes the result into a traceable reviewer workflow.
Product capabilities
What the product needed to do.
Assignment authenticity
Observe typing cadence, edit history, source reuse, and suspicious document events.
Desktop proctoring

Identity verification
Verify the student on mobile before connecting them to an exam session.
Evidence timeline
Turn time-stamped events and media into a review-ready record.
Async intelligence
Run longer evidence and computer-vision jobs away from interactive requests.
