Built for high-trust AI-assisted grading.

Why we built Grade Harbor this way
Grade Harbor was designed by an AI systems leader with experience building human-reviewed AI workflows in high-stakes industries. The product is built around the same principles required in serious AI systems: transparent reasoning, human approval, auditability, and careful handling of sensitive data.
Why teacher control comes first
AI can draft a score. It can explain a pattern. It can prepare feedback. But only a teacher understands the student, the classroom context, the assignment goals, and what feedback will actually help.Grade Harbor is built around that boundary.
What we stand for
These principles are not aspirational. They are design constraints that govern every product decision we make.
Human-in-the-loop, always
AI prepares a draft; the teacher decides. No grade is recorded, no feedback shared, and no action taken without explicit teacher approval. That commitment is enforced in the product — not just claimed in marketing.
Teacher agency first
Teachers set the rubric, define the criteria, override any score, and edit any feedback. The system surfaces information and recommendations — the teacher retains full authority over every instructional decision.
Student data is never sold
Student essays, scores, and skill data exist for one purpose: helping teachers improve instruction. The data is never sold, licensed, or used for advertising. Ever.
FERPA is a hard requirement
Student education records are protected by law and by design. We will sign Data Processing Agreements with institutions as required, and no student data is sent to third-party services without explicit authorization.
