PreGrade is a Chrome extension designed to assist students by providing instant feedback and estimated scores on assignments before submission. This innovative tool integrates seamlessly with the Canvas learning management system, allowing users to upload their work and receive AI-generated evaluations within seconds. The primary aim of PreGrade is to help students refine their submissions based on immediate insights, fostering an environment of continuous improvement.

Beyond just grading, PreGrade employs machine learning algorithms to analyze professors' grading trends and course complexities over time. This feature enables the tool to adapt its predictions based on actual grades entered by the user, effectively learning the grading leniency of individual professors. Key functionalities include tailored feedback for each assignment, a smart learning model that reflects the grading style of each course, and the ability to help students enhance their work prior to final submission.
