A faster way to review essays without handing judgment to AI.
Grade Harbor exists to give writing teachers a practical way to move from essay stack to reviewed feedback faster. AI prepares the draft work; teachers decide what is accurate, useful, and final.

Why this exists
Writing teachers need time back and better next steps.
Essay grading asks teachers to be accurate, fast, fair, and instructional all at once. Grade Harbor focuses on the part teachers actually need help with: preparing rubric-aligned draft evidence so review can happen sooner.
Product boundary
AI can prepare feedback. It cannot know your classroom.
The system can draft a score, explain a pattern, and summarize class needs. Only a teacher understands the assignment, the student, the class context, and what feedback will actually help. Grade Harbor is built around that boundary.
Public promise
The page stays focused on what a reviewer needs to verify: teacher control, rubric-first grading, protected student data, and clear paths to support, legal, privacy, and FERPA details.
Core values
What we stand for
These principles keep the public promise practical: save teacher time, preserve teacher agency, and treat student writing as protected education data.
Draft work teachers can inspect
Control stays with the teacher
Student data has one job
Rubric — persuasive essay
A static rubric example with four writing criteria scored across beginning, developing, proficient, and exemplary levels.
| Criterion | Beginning | Developing | Proficient | Exemplary |
|---|---|---|---|---|
| Thesis and argument | 1 | 2 | 3 | 4 |
| Evidence and support | 1 | 2 | 3 | 4 |
| Organization | 1 | 2 | 3 | 4 |
| Style and conventions | 1 | 2 | 3 | 4 |
- Beginning
- Developing
- Proficient
- Exemplary
Why rubrics matter
Rubrics are more than a scoring tool.
They give teachers and students a shared map for what good writing looks like. When expectations are explicit, AI drafts can be reviewed against the same criteria a teacher would use.
Grade Harbor keeps AI-assisted scores anchored to your rubric, not a generic writing standard. That makes the draft easier to inspect, adjust, and explain before anything is final.
- Criterion-by-criterion scoring keeps feedback actionable.
- Consistent standards across all students in a class set.
- AI scores against your rubric — nothing generalized.
