About
Built by professionals, made for teachers.
Marker is an AI-assisted grading service operated by Hedron Systems, a Cyprus-based software company. We help teachers reclaim their evenings — without taking the marking decisions out of their hands.
Our mission
Grading scanned exams takes hours of repetitive work that teachers could be spending on actual teaching. We built Marker to take that work off your plate — while keeping you fully in control of every result.
How it works in practice
You upload the blank exam, the answer key, and your students' scanned papers. Marker reads each paper page by page and proposes a mark. Before anything is committed, you review the first paper — and every subsequent one if you want to. Nothing is final until you say so.
Where your data lives
All data is stored within the European Union. We're GDPR-compliant and treat your students' work the way you would — it's used only to produce the grading you requested, and you can delete your account at any time, which removes every file and record we hold on you.
Who's behind it
Hedron Systems is a team of certified Microsoft professionals — Microsoft Certified Solution Developers, Microsoft Certified Professionals, and Microsoft Certified Trainers — with a portfolio of software solutions across multiple industries. Marker is one of those solutions, built specifically for the grading workflow we kept hearing teachers complain about.
“Your success is our success.”
