Why Pre-Grading Works
Most students submit their essay and hope for the best. But research on deliberate practice shows that reviewing your own work against clear criteria is one of the most effective ways to improve writing quality. A pre-grader gives you that structured self-review in seconds.
Unlike a basic spell-checker, our AI essay grader evaluates argument logic, evidence integration, and paragraph-level structure. It flags the things your grammar tool misses — weak thesis statements, unsupported claims, and structural imbalances.
Combine this tool with Lorea's full study platform to prepare for essay-based exams: generate mock exams from your course material, practice timed essays, then pre-grade them here before submitting.
