Frequently asked questions
The Winston AI Essay Grader is an AI-powered grading tool built for teachers. It reads student essays against your rubric, suggests scores for each criterion, and drafts detailed written feedback, so you spend your time reviewing and refining instead of starting from scratch. It connects directly with Google Classroom.
No, it’s a first draft, not a final grade. The Essay Grader suggests scores and writes initial feedback based on your rubric, but you review everything before it reaches students. You stay in full control: edit any score, rewrite any comment, and publish only what you approve. Think of it as a grading assistant that does the heavy lifting so you can focus on the judgment calls that actually require a teacher.
Yes. Upload your rubric as-is and Winston AI will grade against your criteria, your point values, and your performance levels, exactly the way you already assess student work. If you don’t have a rubric in a shareable format, you can also build one from scratch inside the tool in a few minutes. Either way, the AI grades to your standards, not a generic template.
Yes. Winston AI is GDPR compliant and SOC 2 certified. Student essays are never stored beyond your session or used to train AI models. Your students’ work stays private. For schools and districts, this means you can use the tool with confidence that you’re meeting your data protection obligations without any extra configuration on your end.
