What is Marking.ai?
Marking.ai is an AI marking platform for schools. It reads typed and handwritten student work, marks it against criteria taken from the marking guidelines you upload, and quotes the words that earned each mark. It drafts feedback for you to edit, and nothing reaches a student until a teacher approves it.
Your marking workflow, end to end
The teacher is the decision-maker at every stage.

Your mark scheme, enhanced by our proven strategies
You can upload a mark scheme and provide additional context such as an examiner's report, model answers and source material. We then utilise that in line with a series of proven marking strategies based on a question's metadata.
- Reads the mark scheme or guidelines you already use
- Criterion by criterion, not an overall impression
- The same standard on every script in the class
Reads handwritten work
Students write on paper. Scan or photograph the scripts and Marking.ai reads them directly - handwriting, typed text and diagrams on the same page.
- Scans and photographs of handwritten scripts
- Several pages per answer, kept in order
- No transcription step
Q12 · Why did the Weimar Republic fail?
The Treaty of Versailles imposed harsh repara reparations on Germany - about £6.6 bn in 1921 - which the Weimar government could not realistically pay. This caused hyperinflation by 1923 and bred deep resentment, fuelling the rise of extremist parties through the late 1920s.

The crossed-out false start is shown struck. The caret-inserted word is resolved into place.
Feedback designed to help your students improve
Every answer comes with high-quality, personalised feedback for each student. Annotated comments, answer based feedback, and student summaries. You're always in control of the feedback structure and tone.
- Drafted from the criteria the work was marked against
- Refers to what the answer did and did not do
- Every comment editable before it goes out
- Nothing reaches a student until a teacher approves it
Data, insights and reporting built in
Teachers can now see which students need support, which questions were the most difficult and where general misconceptions exist. Departments can see the top performing classes and why. Schools can see performance by subject or year group.
- Question-level results, by student and by class
- Median, mean, pass rate and spread on the class you are looking at
- Common misconceptions grouped from the scripts already marked - and not attempted below ten of them
- Built out of the marking itself, rather than entered again somewhere else

What teachers told us
Don't take our word for it - hear from the teachers loving using Marking.ai
Before Marking.ai, feedback often took 5–10 days to reach students - evenings and weekends disappeared into marking. … Turnaround is now days faster, feedback quality is richer and more consistent, and I've been able to set more varied assessment - homework checks, spot tests - without the marking backlog piling up.
Emmanuel Selvarajah
Mathematics teacher, St Albans Secondary CollegeWith 120+ ESL essays weekly, I was drowning. The game-changer? It was able to decipher my students' illegible scrawl, handwriting I'd previously needed a Rosetta Stone for. What took countless hours now takes ninety minutes. I've reclaimed my evenings, my sanity, and given proper feedback instead of panic-scribbled “good effort!”
Robert Morrison
English teacher, St Rose of Lima's CollegeMy biggest marking challenge was providing meaningful, individualized feedback to large numbers of students while still meeting deadlines. … What surprised me most was not just the time saved, but the quality of the feedback. Students have commented on how helpful and detailed it is.

Frequently asked questions
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.
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. A single answer can run across several pages.
What does it cost to try?
Every new account gets 20 free submissions, one time - not per month. The trial exposes the full Pro feature set rather than a cut-down version.
