How Neriah works
Six steps from submission to verified grade. Built for handwritten work, African curricula, and teachers who have been buried under exercise books for too long.

The full workflow
Teacher sets up their class
One-time setup per term. The teacher creates a class, adds students by typing the register or photographing the register page, and selects the education level. Our ground team assists with the first session — under 20 minutes total.
Supported: Grade 1–7, Form 1–6, Tertiary.
Teacher uploads the answer key
The teacher photographs the question paper and correct answers. Neriah OCRs and stores this as the grading reference. No answer key? Neriah generates a marking scheme from the question paper alone — teacher reviews and approves before grading begins.
AI-generated schemes require teacher approval before use.
Student submits their work
The student photographs their handwritten homework and sends it via the Neriah app, WhatsApp, or email. No broadband required. A shared family phone is enough.
Three channels: App (offline-capable), WhatsApp, Email.
Neriah AI Engine grades it
The engine reads the handwriting, compares each answer against the marking scheme calibrated to the selected education level. A Grade 3 composition is not evaluated with the same rigour as a Form 4 essay.
Results returned in approximately 8 seconds.
Teacher receives an annotated result
The teacher sees the original photo alongside an annotated version showing ticks, crosses, and the AI-suggested score. The teacher approves or overrides in one tap. Every final grade is a teacher decision.
Low-confidence submissions are flagged and require full review.
Analytics unlock after 10 submissions
Once a student has 10 graded submissions, Neriah surfaces weak topics, strong topics, score trend, and three personalised study recommendations. Class-level summaries are available on demand.
Analytics update automatically — no configuration needed.

Frequently asked questions
Is student data safe?
All data is stored on encrypted cloud infrastructure. Raw submission images are deleted after 90 days. Grade records are retained for the licence period plus one year. Neriah complies with Zimbabwe's Data Protection Act (2021). We never sell student data.
What if the AI grade is wrong?
Every AI grade is a suggestion. The teacher reviews and approves every grade before it is treated as final. Teachers can override any grade with one tap and an optional comment.
Does it work without internet?
The Neriah app has an offline mode. Students can photograph their work without data, and submissions queue until connectivity is restored.
What subjects does it cover?
Any subject with written answers — Maths, English, Science, History, Geography, Shona, and more. Multiple choice, short answer, and essay questions are all supported.
How accurate is the OCR?
Our target benchmark is 85%+ field-level accuracy on Zimbabwean secondary school exercise books under normal lighting. Low-confidence results are flagged for mandatory teacher review rather than auto-approved.
How long does school onboarding take?
Under 20 minutes for the first teacher session. Our ground team visits the school, demonstrates the app, sets up the first class and rubric, and runs a test marking session.
Does it support tertiary institutions?
Yes. The Institution licence ($199/month) is designed for colleges, polytechnics, and universities still on paper-based workflows.
How is it different from ChatGPT or Google Classroom?
ChatGPT has no structured marking workflow, no curriculum alignment, and no student record-keeping. Google Classroom requires students to have personal devices and reliable internet — neither holds in most Zimbabwean schools.

Contact Kundai →The company
Neriah Africa (Private) Limited was incorporated in Zimbabwe. Neriah Education is the first product — an AI-powered assignment grading platform for African schools. Education is where we started, but it is not the limit of what we are building. The same AI infrastructure that grades exercise books can read insurance claim forms, digitise medical records, and process paper-based workflows across every sector that Africa still runs on paper.
We are building AI infrastructure for Africa. Education is the first application. The foundation data collected through the Neriah Foundation exercise book exchange — real African handwriting, labelled and anonymised — is the asset that makes everything else possible.
