It sits beside the work. Not in another dashboard.

Many AI grading tools create a separate workflow. Grade Drafter starts in Google Classroom, beside the document you were going to grade anyway.

01

Open the submission

Grade Drafter reads the active Google Doc or Slides submission and identifies the student response areas.

02

Link the marking guide once

For worksheets, point Grade Drafter at the completed version. It maps the same answer spaces rather than guessing from page layout alone.

03

Generate a draft

AI-assisted marks, concise comments and overall LPTR feedback are drafted. You can grade one student or let it work through the class.

04

Review, then apply

Teacher review is required. Check the draft, jump to evidence, resolve genuine uncertainties, then decide what to apply. The teacher retains responsibility for the final judgement.

✓
Routine answers stay routine.

Correct and incorrect responses get concise draft feedback instead of paragraphs of filler.

⚠
Uncertainty is explicit.

When an answer genuinely needs judgement, it stays visible for teacher review.

↗
Jump back to the evidence.

Review by category, then move straight back to the response you need to inspect.

Designed around professional judgement

The AI drafts. The teacher decides.

✓
Teacher retains final judgementAI-generated marks and feedback are drafts. The teacher reviews them and decides what is applied or returned to students.
✓
Human oversight stays visibleAmbiguous responses are separated into a genuine “To review” queue rather than being treated as certain.
✓
No Grade Drafter copy of student workStudent work is read from Google Workspace when needed. Grade Drafter does not store submissions.
✓
School-controlled AI connectionFor real student work, use an AI account or API key approved under your school’s AI and data-protection arrangements.
✓
No mystery AI billYou bring the Gemini API key. The provider bills the actual model usage directly.

Pay for the workflow. See the AI cost.

Grade Drafter charges for the workflow, not for reselling AI tokens. Connect your own Gemini API key — or one approved or provided by your school — and see what the underlying model actually costs.

Different work needs different grading.

A worksheet is not an essay. An essay is not a slide deck. Grade Drafter uses a different review pattern for each instead of forcing everything through one rubric-shaped funnel.
