What is CoGrader?

CoGrader is an AI-powered essay grading tool designed to help teachers evaluate student writing quickly and consistently. It analyses essays against customisable criteria and provides detailed feedback on structure, grammar, argumentation, and style. The tool integrates with Google Classroom and other learning management systems, allowing teachers to import assignments directly and distribute feedback to students automatically. Rather than replacing teacher judgement, CoGrader aims to reduce the time spent on initial marking and consistency checks, freeing educators to focus on more meaningful feedback and instruction.
