AI marking tools compared: an honest guide
Last checked: 17 July 2026.
I'm Cheryl, a Head Teacher in a NSW secondary school, and I built MarkMate. That makes this page biased in an obvious way, so it plays fair: what each tool actually does, according to its own site, and who each one suits. Where a competitor does something well, it says so.
This page is mainly for teachers choosing a tool for a faculty or school. Students after free essay help: jump to the student tools further down.
First, the thing that confuses everyone: there are at least 4 products called MarkMate. This site, markmate.education, is the one built by a NSW teacher for Australian schools. The others are covered at the bottom, in case the MarkMate you were looking for is one of them.
The short answer
Which tool fits depends on the job in front of you.
A NSW teacher marking class sets across any faculty: MarkMate. It's the only tool here that marks against your rubric in every NSW subject area, not just English, with AI detection and batch upload built in.
An English faculty that also wants a resource library: Jeddle. English only, but the study guides and comment banks are a real library, and it's in 150+ Australian schools by its own count.
A senior English teacher who wants published accuracy numbers and compliance badges: Edexia. English only (VCE, HSC, QCE, WACE, IB), free for teachers, SOC 2 and ISO 27001 certified, Australian servers.
An HSC English student who wants free help: Artie by Art of Smart. Free, NESA module rubrics, predicted marks. It's the free front door to a tutoring business, and it's good at what it does.
A student practising past papers across states: AusGrader or Study Marker. Exam-practice platforms first, essay markers second.
Tracking whole-school writing growth over years: Mark My Words. Skill analytics and NAPLAN alignment; pricing is by demo.
The rest of this page is the detail behind those calls.
What's the best AI marking tool for NSW schools?
For a NSW school marking across multiple faculties, none of the other tools on this page combines rubric-aligned marking in 30+ NSW subjects, AI detection with a teacher-facing evidence report, and a class dashboard; MarkMate is built as exactly that combination. For senior English alone, Jeddle and Edexia are both worth trialling, and Artie is purpose-built free help for HSC English students. The right tool depends on the job, which is why the rest of this page shows the working.
Teacher-side tools compared
Everything in this table comes from each product's public site on 17 July 2026. “Not published” means exactly that. One note on the Marking.ai column: its site publishes the least detail of the five, so its cells say “not stated” more than the others. It's included because it's likely the first tool you'll meet in a search, and what a vendor's public pages don't say is worth knowing in itself.
| Feature | MarkMate | Jeddle | Edexia | Mark My Words | Marking.ai |
|---|---|---|---|---|---|
| Built for | NSW Years 7–12, all faculties | Australian schools, English | Senior English (VCE, HSC, QCE, WACE, IB) | Australian schools, writing skills Years 1–12 | High school and university, international |
| Subjects | 30+ NSW subjects | English only | English only | Writing across subjects | Any (no curriculum alignment stated) |
| Marks against your rubric | Yes, criterion by criterion | Yes | Yes, calibrated to study designs | Yes, plus 1,000+ tracked skills | Not stated |
| Handwritten work | Yes | Yes | Yes | Yes | Yes |
| AI detection | Yes, 4-category evidence report plus cross-student similarity | Not mentioned | Yes, with keystroke replay | Not mentioned | Not mentioned |
| Batch marking | Yes, 30 files with live progress | Not stated | Yes | Yes | Yes |
| Price entry | Free plan; teacher plans from $9.99/month AUD | Not published | Free for teachers | Not published | Not published |
| Data | Sydney database; no student names sent to the AI; never used to train AI | Not stated on page | Australian servers, SOC 2, ISO 27001, ST4S | Not stated on page | Not stated |
Two honest notes on that table. Edexia holds organisation-level certifications; MarkMate doesn't. Our authentication provider (Clerk) is SOC 2 Type II compliant, the database lives in Sydney, and no student names ever reach the AI; the compliance page carries the detail, and we'll complete your school's vendor assessment or DPA on request. Edexia also publishes accuracy testing (81.2% exact match with teacher grades, 98.3% within 1 mark, on 579 essays at one school).
If you teach senior English only, try both. The moment you also mark Modern History source analyses, Business Studies reports, or PDHPE long responses, the English-only tools are out of the race, and that's most of a school.
Student-side tools compared
| Feature | MarkMate | Artie | Study Marker | AusGrader | markmateai.com.au |
|---|---|---|---|---|---|
| Built for | NSW Years 7–12, any subject | HSC English | HSC/VCE exam prep, multi-subject | Year 12 past papers, all states | Australian Years 7–12 essays |
| Marks against your actual task rubric | Yes, upload the task notification | NESA module rubrics | Exam-style criteria | Official past-paper marking guides | Upload a rubric |
| Free | Demo free, no sign-up, up to 500 words | Free plan | Free trial, then paid | Not published | Free to try |
| Handwriting | Yes, photograph each page | Not stated | Not stated | Photo upload | Not stated |
| Teacher visibility | Yes: share a class link, see every check on your dashboard | No dashboard mentioned | No teacher platform mentioned | Some school tools | None visible |
Two more come up in the same searches: MaxHSC (instant band-direction feedback for 5 HSC subjects) and Polarbear (free examiner-style marking for VCE, HSC, and QCE). Their public sites don't say enough to compare them fairly, so they get a mention here rather than a guess in the table.
The free student tools are exactly that: free, and useful, and pretending otherwise would insult your intelligence. What none of them offer is the loop MarkMate is built around: a teacher shares the link, students check drafts against the real task rubric, and the teacher sees who checked what before the pile lands. Self-check without the teacher in the loop is a study tool. With the teacher in the loop, it's formative assessment.
The other MarkMates
Different products, same name. None of them are us, and none of them are NSW-curriculum tools.
markmate.ai is an international AI essay marking site for students and teachers. It's usually the first result when you search the name; it isn't Australian.
markmate.co.uk (Mark Mate) is a UK voice-to-text marking assistant, all subjects, £4.99 a month, known from Dragons' Den. If you saw MarkMate on television, that's the one.
markmateai.com is a UK lesson-planning and resource generator in public beta. It doesn't mark work.
markmateai.com.au (also markmate.live) is an Australian student essay marker with a very familiar pitch. No relation, no teacher dashboard, students only.
If a colleague says “we tried MarkMate and it didn't do X”, it's worth one question: which one?
Frequently asked questions
What's the best AI marking tool for the HSC?
There's no single best, there's a best fit for the job. English-only faculties have real options in Jeddle and Edexia; students have free tools in Artie and AusGrader; MarkMate is the fit when one tool has to mark against the rubric across every faculty, flag AI use, and keep the teacher in the loop.
Is MarkMate the same as Mark Mate UK or markmate.ai?
No. markmate.education is built by a NSW Head Teacher for Australian schools; the UK Mark Mate is a voice-to-text marking assistant and markmate.ai is an international essay marker. Same name, different products.
Is there a free AI marking tool for Australian teachers?
Several, with different ceilings. MarkMate's free plan includes 2 assignments and 10 student checks a month, with AI detection on the Teacher Pro plan; Edexia says it's free for teachers; Artie and Polarbear are free on the student side.
Can AI marking tools read handwritten work?
The serious ones can. MarkMate, Jeddle, Edexia, Mark My Words, and Marking.ai all state handwriting support; MarkMate has students photograph each page, then verifies the transcription before marking.
How accurate is AI marking?
Treat every tool's marks as a first pass for your judgement, not a verdict. Edexia publishes test figures (81.2% exact match with teacher grades at one school); MarkMate's position is that the rubric-aligned first pass does the repetitive work and the teacher makes the calls that matter, which is why every mark and comment stays editable.
Can I use AI marking tools for subjects other than English?
Most of the Australian tools can't; Jeddle, Edexia, Artie, and Dodie are English-only by design. MarkMate marks against rubrics in 30+ NSW subjects across every faculty, which is the main reason it exists.
How do I know which AI marking tool my school will approve?
Look for Australian data hosting, a public compliance page, and a supplier willing to complete your school's vendor assessment or DPA; an ST4S badge (the national schools assessment) is the strongest signal, and Edexia holds one. MarkMate publishes its full compliance detail, hosts data in Sydney, and completes school assessments on request.
Is MarkMate the same as the marking tool on Dragons' Den?
No, that's Mark Mate UK (markmate.co.uk), a British voice-to-text marking assistant. This MarkMate is markmate.education, built by a NSW Head Teacher for Australian schools.
