Our Commitment to Teachers

In November of 2022, ChatGPT’s release opened the Pandora's box on massively available AI-generated content.

At GPTZero, we immediately knew the new challenge that AI could pose to information transparency and academic integrity. Within three months, we built the first AI detector with more than 300,000 teachers from 45 states and 30 countries using our tool to detect AI. We now have more than 3 million users and partner with universities and school systems around the world.

We’re evolving to keep up with the latest in AI detection and offer educators more holistic education solutions: writing reports, origin analysis, advanced scan, and interpretability metrics. With teachers, we want to empower you with the guardrails on technology in the classroom to foster originality, encourage critical thinking and prepare your students for the future with AI.

Much will change with AI technology, but our commitment to educators remains steadfast.

Sincerely,

Edward Tian

Founder & CEO, GPTZero

AI Reviewer evaluates student writing and suggests grades and feedback based on your rubric. It's a grading assistant that speeds up marking by allowing teachers to create shareable templates calibrated to their specifications and perspectives.
AI Reviewer can easily grade and provide feedback on mechanics (grammar, spelling, citation formatting, quote checking), in addition to contributing a second opinion on higher-order concerns. Review templates can also be shared with students so they can receive formative feedback on assignments before final submission.
AI Reviewer makes your grading more consistent and increases the quality and diversity of your feedback by providing a second opinion on each assignment. Our tool works like a safety net, helping ensure that you don't miss obvious content issues or let your emotions cloud your grading decisions.
Educators can leverage the expertise of the larger teaching community by sharing templates or using templates created by domain experts hired by GPTZero. Templates can also be shared with students as a source of formative feedback on early drafts.

AI Reviewer is a force multiplier, not a teacher replacement. However, just because our tool shouldn't be used like a magic grading wand doesn't mean it can't save you time, make your grading more consistent, and increase the quality and diversity of your feedback.

As always, GPTZero recommends that educators disclose their AI use to their students, both to model appropriate behavior and to prevent student confusion over the source of personalized feedback.

AI Reviewer integrates with Google Classroom, Canvas, Blackboard, and more. You can import assignments and then grade directly in the platform, without having to resort to manual uploads.
All files are encrypted and our platform is FERPA and GDPR compliant. AI Reviewer for teachers only collects the data you need to grade assignments and we never sell or share your information.
Our AI grading system is highly accurate for standard assignments, but grading written assignments is inherently subjective. While our tool provides a suggested score, we believe teachers should make the final call.
AI Reviewer can be used to evaluate any written assignment type, from lab reports to comedy sketches. Assignments can be copied directly into the editor, or uploaded as word docs, Google Docs or PDFs. AI Reviewer also supports multi-file uploads.
While grading is most accurate in English, the tool also supports Spanish, French, Portuguese and German.
