The problem

Manual grading is broken.

Teachers lose entire weekends grading answer sheets by hand. Students wait days for results, then have no way to understand why they lost marks.

Disputes become arguments. Feedback becomes a red mark without context. And school administrators have no visibility into performance patterns until it's too late.

How it works

From paper to results in minutes.

A three-step pipeline that eliminates grading busywork while giving students radical transparency.

01

Upload & define

Scan handwritten answer sheets. Define your question paper with expected answers, keywords, and grading rubric.

02

AI grades automatically

OCR extracts handwritten text. AI evaluates each answer against your rubric — awarding partial credit with detailed reasoning.

03

Review & publish

Override AI scores where needed. Publish results and students instantly see scores, expected answers, and explanations.

Platform

Everything your school needs.

Built from the ground up for the full exam lifecycle — from answer key to final report card.

Handwriting OCR

Google Vision extracts text from scanned answer sheets with high accuracy across handwriting styles.

Context-aware scoring

AI understands conceptual equivalence, awards partial credit, and adapts to OCR artifacts automatically.

Radical transparency

Students see their extracted answer, expected answer, and a per-question scoring rationale.

Structured disputes

Students raise disputes. Teachers accept or reject with written explanations. Every change is audited.

Performance analytics

Score distributions, subject-wise trends, and dispute rates at the class, division, and school level.

Audit logging

Every score modification, publication, and dispute resolution is tracked with user, timestamp, and reason.

Questions

Frequently asked.

How accurate is the AI grading?
The AI handles objective and semi-objective answers very well — awarding partial credit based on keyword matching and conceptual equivalence. For descriptive essay-type answers, we recommend teachers review before publishing. Every score is shown with reasoning, and teachers can override any score in seconds.
What types of answer sheets are supported?
Scanned handwritten answer sheets (JPEG, PNG, WebP) and PDF scans are supported. Google Cloud Vision handles most handwriting styles with high accuracy. OCR confidence scores help teachers prioritize which sheets need closer review.
Is PaperArch free?
PaperArch is currently free for early schools. We use Google Gemini's free tier for AI grading (1,500 requests/day) — enough for small to medium schools. Paid plans with higher limits will launch later.
How is student data protected?
Data is isolated per school at the database level. Every API request is authenticated and scoped. All score changes are logged in an immutable audit trail. Traffic is encrypted with TLS 1.3 and HSTS.
Can students contest their scores?
Yes — the dispute system is a first-class feature. Students raise structured disputes with written reasoning. Teachers respond with explanations and can adjust scores (logged in the audit trail). Both parties are notified throughout.
