Draft feedback is ready to edit. Nothing is final until the teacher locks the grade.
The grading pain
The work is not just slow. It is disconnected from instruction.
Teachers do high-effort grading, then still have to translate every score into what students and the class need next.
Teacher payoff
Faster drafts should lead to better teaching decisions, not a black-box final grade.
Grade Harbor prepares the score evidence, feedback language, and class patterns. You decide what is accurate, what changes, and when a grade is ready to lock.
- Teachers lose nights and weekends to repeated essay stacks.
- Feedback arrives after students have moved on from the assignment.
- Class-wide writing patterns stay hidden inside individual papers.
- AI prepares rubric-aligned draft scores, reasoning, and feedback.
- Teachers review, edit, override, and approve before anything is final.
- Skill patterns turn grading evidence into the next instructional move.
