Marking transformed

See the difference Marky makes to a typical teacher's week.

Without Marky

  • Approximately 5 hours marking a class set of papers by hand
  • Inconsistent marking across 30 papers
  • Generic feedback: "needs improvement"
  • No analytics so you guess which topics need work
  • Weekends and evenings lost to the marking pile

With Marky

  • Approximately one hour for a class set of 30, or 15 minutes for a single paper on demand
  • The same mark scheme applied consistently to every paper, without fatigue or drift
  • Detailed, personalised feedback per question
  • Instant analytics so you see exactly where gaps are
  • Get your evenings back and spend time planning, not marking

How Marky works

Three steps: upload, mark, and share.

Learn more about how it works
1

Upload Mark Scheme & Papers

Upload the mark scheme first, then the class set. Scan the papers or photograph them on a phone: PDFs and images both work, with no conversion needed.

2

AI Marks Every Answer

Our AI reads each answer, compares it against the mark scheme criteria, and assigns marks, as a trained examiner would.

3

Review & Share

Get detailed results with scores, grades, and feedback. Share with students through the portal or export reports for parents and leadership.

How marking accuracy is verified

Every mark is measured against examiner marking, independently verified, and returned with the reasoning attached.

99.8% within two marks

and 92.4% marked exactly

Measured against examiner marks

Across 3,276 question sections marked by a verified examiner, spanning GCSE and AS mathematics and A-level physics, 99.8% of Marky’s marks fall within two marks of the examiner’s, 98.9% within one, and 92.4% match exactly. At AS and A-level, every section falls within two marks. Section counts are published because a percentage without a denominator is not evidence.

2 passes

applied to every paper

Two independent marking passes

A second verification pass re-reads the paper against the mark scheme and challenges the first set of marks. Disagreements between the two passes are resolved before the mark is released, and the reasoning remains attached to the question.

6 flag reasons

each with a stated reason

Targeted review, with stated reasons

Rather than requiring a review of every paper, Marky identifies those warranting human attention and states why. The reason may be a mark near a grade boundary, handwriting that could not be read confidently, a possible integrity concern, disagreement between marking passes, arbitration, or wide variance. The remainder can be signed off as returned.

The most relevant benchmark is your own. During the 3-day trial, submit a set of papers you have already marked and compare the results question by question against your specification and your students’ handwriting.

Frequently asked questions

How accurate is the AI marking?
Measured against a verified examiner across 3,276 question sections spanning GCSE and AS maths and A-level physics: 99.8% of Marky's marks are within two marks of the examiner's, 98.9% are within one, and 92.4% are exactly the same mark. At AS and A-level, every section is within two marks. Marks are applied from the same mark scheme criteria a human examiner uses, papers that need a second look are flagged for you with the reason, and you can always review and adjust before sharing results.
What file formats do you accept?
Student papers and mark schemes can be uploaded as PDF files. You can scan handwritten papers using your phone camera or a document scanner. Marky's AI reads handwriting accurately.
Is student data secure?
Absolutely. Marky is built with security and GDPR compliance at its core. All data is encrypted in transit and at rest, hosted on secure cloud infrastructure, and we maintain comprehensive audit logs. Student data is never used for AI training.
Can I integrate with my school's LMS?
Yes. On School plans, you can connect your learning management system to import students and class groups automatically. We are continually adding integrations based on teacher feedback.
How long does marking take?
A class set of approximately 30 papers is returned in approximately one hour, measured end to end on a full cohort. Papers are processed together rather than sequentially, so most of that time is fixed overhead and substantially larger sets do not take proportionally longer. A notification is sent when results are available.
