The grading loop is broken
- Teachers spend 4–6 hours per class set grading essays — time that cannot be spent on instruction.
- Feedback arrives days after submission, when students have already moved on to the next assignment.
- Grading is disconnected from instruction — patterns across a class remain invisible without hours of manual analysis.
Grade Harbor breaks the loop
- AI prepares draft scores and feedback for every essay against your rubric — with per-criterion reasoning you can read, edit, and approve.
- Review, override, and approve grades on your schedule. Feedback is ready when you are — not when manual grading finally ends.
- Skill profiles update automatically across every assignment — you see exactly which students need help and what to teach next.
Everything you need to grade with confidence
AI grading with transparent reasoning
Each criterion scored individually with a written justification you can read and verify.

Persistent skill tracking across assignments surfaces gaps before they widen.
Teacher-guided instruction
Instructional priorities surfaced from real student data — not gut feel.
Human-in-the-loop, always
AI prepares; you decide. No grade is recorded until you approve it.
