Learn How It Works

Why Teachers Love It

Save time, improve fairness, and keep student data private — fast, mobile-first grading that teachers trust.

Explainable and Evidence-Backed Scoring

Scores are explained, not guessed. Each decision is linked to visual evidence in the original answer image and supported by a clear, step-by-step rationale. Review becomes fast, transparent, and auditable.

Grade an Entire Class in Minutes

No more manual correction marathons — the AI handles handwriting recognition, scoring, and feedback automatically. Reclaim your time to focus on what truly matters: teaching and mentoring your students.

Detailed Control & Custom Scoring Rules

Set precise scoring schemes, including partial credit and question-specific rubrics. Upload a question sheet with detailed marking rules, and the grader automatically applies them — ensuring both consistency and flexibility across all exams.

Mobile-Friendly Workflow

Capture answers with your phone or upload images — no scanner needed.

Secure & Private

Open-source and auditable. Self-host to keep data on your infrastructure and retain full control over student data.

Simple 3-Step Process

Upload the question sheet, capture answers, and receive graded results — no setup or model training required.

How It Works

Get started in three simple steps

1

Upload Question Sheet

Upload a PDF containing your exam questions, correct answers, and the mark allocation for each question. This will be used as the grading reference.

2

Capture Answer Sheets

Take photos of students' answer sheets using your device's camera or upload existing images. Multiple images per student are supported.

3

Get Instant Results

The AI analyzes handwriting and automatically grades each answer. Get detailed feedback, scores, and explanations for each question.
