Not just scoring. Real feedback that improves writing.
An essay checker reviews your writing and highlights what needs attention. Most tools stop at fixed, generic checks. Clasa works differently: you define how each evaluation should happen, so the review follows the rubric or instructions you provide instead of preset logic alone.
That means grading is never one-size-fits-all. Clasa evaluates writing against the structure, priorities, and standards you set, whether you're focused on argument quality, clarity, or organization. Every score is backed by feedback that explains how the essay was assessed, so the outcome is transparent and easy to act on.
Use Clasa as an essay evaluator, essay reviewer, or AI essay grading tool across evaluation essay formats, college essays, and academic writing. Clasa even helps you learn how to write an evaluation essay by showing exactly where the writing breaks down and how to fix it in a single pass instead of several manual readings.
When originality matters, Clasa's built-in AI detection lets you check whether content may be AI-generated, available right alongside your essay grading results.
