Frequently asked questions
The questions teachers and school leaders ask most often.
What is Marking.ai and how does it work?
Marking.ai is an AI marking platform for secondary schools. A teacher uploads the mark scheme they already use and their class's work - typed or handwritten - and every answer comes back marked criterion by criterion, with the exact words from the student's answer that earned each mark, plus drafted feedback. The teacher reviews, edits anything they disagree with, and approves. Nothing reaches a student before that.
What it marks, and how
Will it replace or deskill teachers?
No. Marking.ai drafts; teachers decide. Nothing is released until a teacher approves it. It removes the repetitive first pass so teachers spend more time teaching and on the judgement only they can make.
Isn't AI marking inaccurate?
Marking.ai marks to your marking guidelines and mark scheme criterion by criterion, and shows the evidence behind every mark - so it's accurate and auditable, not a black box. It stays consistent across a whole class, and a teacher reviews and approves every mark before it reaches a student: a faster first pass, not an unchecked final mark.
What kinds of assessment can it mark?
Assessments with multiple questions, both exam-style and essay-style - it is at its best on subjects that ask for longer written answers. It reads typed and handwritten work and the images on a page, marks each answer against your criteria, and a teacher approves every mark.
Can it mark handwritten work?
Yes. Handwritten scripts are read directly from an uploaded scan or photograph, so work does not need to be typed up first. One answer can span several pages.
Can it mark maths and science?
Mathematics, Further Mathematics and Statistics are supported subjects, and the sciences are covered. We publish accuracy evidence subject by subject, and we have not yet run a study on equation or diagram marking - so we describe those as supported without making an accuracy claim we cannot yet back. The evidence and accuracy page explains how we measure it.
Do I have to change the mark scheme I already use?
No. You upload the marking guidelines or mark scheme you already work from, and Marking.ai marks against those.
Which subjects does it cover?
English, Maths, the Sciences, the Humanities, Languages, Business and Computing - all the common curriculum subjects - across UK GCSE and A-Level, South African NSC and CAPS, and Australian HSC, VCE and QCE, plus an "Other" option. The subject is read from your marking guide and you can change it.
How does it match answers to questions in a multi-question script?
It works through the uploaded script and marks each answer against the matching question and its criteria, so marks land on the right sections even when everything is submitted in one document.
What is the re-mark feature?
If something changes - new information, or a student query - a teacher can re-mark a question and review the new result before anything is shared. Re-marking a question does not use up your submission allowance.
Trying it and uploading work
Is there a free trial?
Yes - every new account gets 20 free submissions, one time (not per month), with the full Pro feature set, and no payment card is needed to start.
How do I get started?
Create a free account and upload a mark scheme and a class set - there is no setup project and no data migration. If you would rather see it first, book a demo and we will mark your own work live.
What format should I upload in?
PDF. Typed and handwritten work are both fine - if you have photos of a script, save them as a PDF first, and a clear, well-lit image reads best.
Can students upload their own work?
Yes. A teacher can share an upload link that a student opens without an account - on a phone or a computer - and submit their work. The mark goes to the teacher first, and a student never sees a mark until the teacher has reviewed and shared it.
Feedback, control and insights
Does it give feedback as well as marks?
Yes. For each question it drafts feedback you can edit and share, alongside a breakdown of where marks were earned and lost - with the student's own words quoted as the evidence behind each mark.
Can I edit the marks and feedback?
Yes, and you are meant to: every mark and comment is a proposal until you approve it. Change anything you disagree with, then release it. Nothing reaches a student before you do.
Can I shape the feedback style?
You can give Marking.ai standing instructions about the feedback you want - its focus and its tone - so the drafted feedback matches how you teach and your school's marking policy.
What reporting do I get?
Question-level results for the individual student and for the class that sat the assessment - where marks were won and lost, and the common errors across the class. Cohort, department and whole-school attainment reporting are not available today.
Does it detect AI-generated answers or plagiarism?
Not yet - AI-detection tools are still unreliable, and we would rather not ship one we cannot stand behind. If that is a concern for your school, we are happy to talk through approaches and third-party tools.
Student data and security
Is student data safe with Marking.ai?
Student work is encrypted in transit and at rest, stored in the EU, and reachable only by the teacher who uploaded it - and a teacher approves every mark before a student sees it. Where data is processed, who our sub-processors are, and how deletion works are all set out on the security pages.
Do you use student work to train AI?
No. We do not use student work, marking guides, marks or feedback to train, fine-tune or develop any AI model - ours or anyone else's - and our AI provider is contractually barred from using it to improve its own models.
Where is student data stored?
Your data is stored in the EU (Frankfurt). AI processing and transactional email run in the United States, under Standard Contractual Clauses and the UK Addendum. The platform security page has the full detail.
Are you GDPR and POPIA compliant?
For student work the school is the controller and we are the processor, under a data processing agreement. Data is stored in the EU, never used to train models, our sub-processors are published, and we have a registered Information Officer for POPIA. There is no official 'GDPR certification' to hold, so we document how we meet the framework rather than claim a badge - the compliance pack and data-protection pages set it out.
How do we delete our data?
Ask us and we will do it - for a school, we delete or return all student data within 30 days of your written instruction under our DPA. Deleting work in the product removes it from your account immediately; permanent erasure of the underlying records is available on request.
Plans and billing
How much does it cost?
Individual plans are $29, $49 and $89 a month (Starter, Pro and Plus), each with a monthly submission allowance. Whole-school licences cover the school on a pooled annual allowance and are agreed with us directly. All payments are processed in US dollars.
What payment options are there, and can I cancel?
Individual subscriptions are paid by card through our payment provider, Lemon Squeezy, as merchant of record. You can cancel at any time; cancellation takes effect at the end of the billing period, and any top-ups you have bought do not expire.
Do you offer refunds?
A first subscription payment carries a 14-day money-back period. Refunds are processed by our payment provider under its terms.
Do you integrate with my school's LMS?
Not yet - we are focused on the experience on our own platform. If your school would like a bespoke integration, get in touch and we will talk it through.
Assessment terms explained
Plain-English definitions of the vocabulary used on this page.
- AI markingAI marking is the use of artificial intelligence to assess student work against defined criteria - a mark scheme or a teacher's own marking guidelines - and to draft marks and feedback for a teacher to review.
- Assessment for learningAssessment for learning is the practice of using evidence of what students currently understand to decide what to teach next, and to help students see what they need to do to improve.
- Assessment objectivesAssessment objectives are the categories of skill a qualification tests - commonly labelled AO1, AO2 and AO3 - each carrying a defined share of the available marks.
- Comparative judgementComparative judgement is an assessment method in which markers repeatedly choose the better of two pieces of work, and those paired decisions are combined statistically into a rank order.
- Criterion-referenced assessmentCriterion-referenced assessment judges work against defined standards of what a student should know or be able to do, rather than against how other students performed.
- ExemplarAn exemplar is a piece of work - often a real student answer - presented with its marks and commentary to show what a particular standard looks like in practice.
