The access gap
The report exists.
You are not the reader.
This is the honest reason people search for a Turnitin alternative, and it has nothing to do with which engine is better. It is a question of who the product is sold to. The result is generated for the institution, arrives in the marker's view, and by the time it exists your submission is already in.
An institutional suite
Turnitin is a plagiarism-detection product licensed by schools, universities, and publishers. The customer is the institution, and the account, the settings, and the thresholds all belong to it.
Inside the similarity report
Its AI writing indicator is delivered alongside the similarity report in the instructor's view, in whatever LMS the institution runs. The report is a marking tool, and it is built to be read by the person marking.
No login to go and get
As an individual writer there is generally no way to sign up and run it on your own draft. If your institution has enabled a practice or draft submission folder, that is the one route to your own result — ask before you assume you have one.
None of that is a criticism. An institutional integrity suite is supposed to sit with the institution, and bolting a student-facing self-service tier onto one would create obvious problems of its own. But it does leave a real gap. A writer working in good faith — who used a model to unstick a paragraph, or who simply writes in the flat, careful register that gets misread — has no way to look at their own draft the way it will be looked at. The only moment that look is actually useful is before submission, and that is exactly the moment it is unavailable.
Before you submit
A pass over the draft,
not a score to beat
The useful version of this is not sanding a document until a number drops. It is finding the paragraphs where you let a model do the thinking and putting your own thinking back in — which is the same edit that makes the essay better.
Scan the draft you are actually going to submit
Not the outline and not the version before the edit pass. The point is to see the document as it stands, while there is still time to change it.
Read the shaded sentences, not the headline
Every sentence gets its own score on a four-step strength scale, shaded in place. The dark lines are where the writing stops sounding like you, and those are the lines to reread out loud.
Put your own thinking back in
Flagged passages are usually the ones where you let a model do the reasoning: connective filler, tidy summaries of a source you did not really engage with, conclusions that restate rather than argue. Replace them with the specific thing you actually think.
Rescan and keep your working
Run it again after the rewrite to see whether the shading moved. Keep your notes, outlines, and version history regardless — process evidence is worth more in an academic conversation than any detector output, ours included.
Read this part
Three things a
self-check is not
Every one of these matters more on a page aimed at students than a feature list does, so they are stated here rather than in the small print.
This is not a prediction of your school's result
A verdict here says what this engine thinks about your text. It does not and cannot tell you what any institutional checker will report on the same document. Different training data, different thresholds, different answer.
A clean scan is not a clearance
Nothing on this page grants permission to submit AI-written work as your own. If your course has an AI policy, that policy is the thing that governs — a detector result does not override it in either direction.
Your own writing can still get flagged
Formal, tightly structured, heavily edited prose is the hardest kind for any detector to read, and non-native English is harder still. If you wrote it and it comes back dark, that is a reason to keep your drafts, not a reason to rewrite until a number moves.
On benchmarks
We publish no head-to-head benchmarks and no accuracy percentage — not for markhuman and not for Turnitin. We have no third-party-verified figure for either, and inventing one on a page aimed at students would be the least defensible thing a detector could do. No detector is perfect. A report here is evidence to weigh, especially on short passages, non-native English, and heavily edited drafts — never proof on its own, and never a substitute for your own account of how you wrote something.
What the detector does and does not claim is set out in more detail on the AI detector page.
FAQ
Student questions
Access, false flags, what an AI-Assisted verdict means for coursework, and what happens to the text you paste.
Can I run Turnitin on my own essay before I submit it?
Generally not directly. Turnitin is licensed to institutions and its AI writing indicator is surfaced inside the instructor's view of the similarity report in the school's LMS, so the result is produced for the institution rather than for the writer. Some courses set up a practice or draft submission folder that lets students see a report on their own work — if yours has one, use it, and ask your instructor if you are not sure. That access gap is the reason a self-check tool is useful at all.
If markhuman says Human-Written, will my university's checker agree?
Nobody can honestly promise you that, and you should not trust a page that does. Detectors are trained on different data and set their thresholds in different places, so two of them can read the same paragraph differently. Use this as a private read on your own draft while you can still change it — not as a guarantee about a result you will not see.
I wrote every word myself and it came back flagged. What should I do?
First, do not rewrite it into something worse to chase a score. False flags land hardest on formal, tightly structured writing and on English written by non-native speakers. Read the shaded sentences and check whether they are genuinely generic — if they are, sharpening them is a real improvement. Then make sure you can show your process: outlines, notes, draft history, and browser or document version history are the evidence that actually settles these conversations.
What does the AI-Assisted verdict mean for a coursework submission?
It means the text carries both a human and a machine signature — a model draft you edited, or your draft that a model rewrote. Whether that is allowed is a question for your course policy, not for a detector. Many policies now permit assistance if it is declared and prohibit it if it is not, and the middle verdict is there precisely so that situation has a name instead of being rounded into one extreme.
Is it free, and do I need an account?
No account and no card. You get 50 scans a day at up to 2,500 words per scan, which covers most essays and assignments in one pass; anything shorter than 50 words is too short for the engine to score reliably. Longer dissertations and higher monthly volumes are what the paid plans are for.
Do you keep a copy of my essay?
No. Text is processed in memory to produce the score and discarded when the response returns. It is not retained, not added to any repository, and not used for training. That is a meaningful difference from submitting a draft anywhere it gets stored — a self-check should not create a record of your unfinished work.
