GradingPen is an AI essay grading tool for teachers, with a student AI tutoring feature called Vero. Its core positioning is to connect essay uploads, rubric-based grading, feedback generation, grade export, and class analytics into a single teaching workflow. The website claims that an essay can be graded in under 30 seconds, and that the product is already used by 1,000+ teachers.
The product supports pasted text, PDF, Word, and image uploads, as well as photo recognition for handwritten essays. Based on rubrics uploaded or created by teachers, the AI generates personalized feedback across dimensions such as content, structure, grammar, and argumentation, and also provides class-level trend analysis. Its integrations are fairly comprehensive, with support for Google Classroom, Google Drive, Canvas, Schoology, Moodle, SEQTA, Compass, and CSV gradebook export. Microsoft Teams, RM Unify, and a public REST API are still on the roadmap. It also offers academic integrity flags that can highlight suspected AI-generated content, inconsistent voice, or suspicious patterns, but it does not disclose detection accuracy.
The free plan includes 15 grading runs and does not require a credit card. Student costs $7.99/month and includes 50 AI tutoring sessions. Teacher Pro costs $199/year and includes unlimited essay grading, custom rubrics, class analytics, bulk uploads, grade export, and FERPA-compliant data processing. The School plan costs $2,499/year for up to 25 teachers, while District pricing is custom.
Its strengths are a focused use case, a clear onboarding path, and tight integration with mainstream overseas LMS platforms, making it suitable for bulk grading in real classroom settings. Statements such as FERPA compliance, not selling or sharing student data, and not using student data for third-party training also improve its credibility for school adoption. The limitations are that the website does not disclose the underlying model, validation of scoring consistency, plagiarism-checking coverage, or false-positive rates. AI grading results still need teacher review. For Chinese, it only states support for Mandarin and 15+ languages, without clarifying whether the interface is localized into Chinese or how well it grades Chinese essays.
It is better suited to K-12 and university teachers, schools, and districts that use systems such as Google Classroom, Canvas, and Moodle. There is no clear information on access from mainland China, supported payment methods, or local compliance, so availability is unknown. If it is not usable, alternatives include Gradescope, Turnitin, Class Companion, or using ChatGPT/Claude with custom rubrics to replace part of the workflow.
