There is something most students do not find out until it is too late.
When your university runs your dissertation through Turnitin, two scores are generated, i.e. a similarity percentage and an AI detection score. Your tutor sees both. You see neither.
Students have no access to their own Turnitin AI score. It is not shown in the student submission portal. It is not emailed to you. The first time you find out your score is high is when your department contacts you about it — after submission, after the deadline, when it is already too late to do anything.
Premier Check exists to close that gap. For £2.99, we run your dissertation through a full AI and similarity scan before you submit, using the same detection technology your institution uses, and deliver the complete report directly to you in minutes. Your document is never stored in any student repository.

🔒 Important for 2026: University AI detectors have a known false positive rate, especially for non-native English speakers. Our report lets you see flagged content before you submit, so you can fix it. Your document is never stored in any student repository.
Why Students Choose Premier Check Over Free Tools
Free tools like GPTZero and Quillbot give a rough estimate. But they miss what actually matters: the full similarity breakdown, AI detection flags, and human review that UK universities expect.
AI + Similarity in One Report
Free tools check either AI or plagiarism—not both. Our Premier Check combines both detections in a single PDF, using the same technology as institutional Turnitin.
Never Stored in Any Database
Free tools often store and resell your data. Premier Check never adds your work to any student repository and permanently deletes your file after 30 days.
Reviewed by UK Academic Editors
Every report is verified by a qualified UK academic who interprets your results—spotting safe citations versus genuinely flagged content.
💡 Did you know? 4% of human-written work gets falsely flagged as AI by Turnitin. Non-native English speakers are most at risk. Checking before you submit is the only way to avoid an unexpected academic integrity review.

Frequently Asked Questions
Is this the same as my university's Turnitin check?
Yes — we use the same licensed detection technology. The similarity %, AI flags, and source breakdown will be nearly identical to what your professor sees. The key difference: your file is never stored in any student database, so it won't clash with your final university submission.
I wrote it myself. Can Turnitin still falsely flag my work?
Unfortunately, yes. University AI detectors have been shown to produce false positives at rates up to 15%, particularly for non-native English speakers and those writing in a formal, structured academic style. Our Premier Check lets you see exactly which sections are flagged before you submit, giving you time to revise and avoid an unfair accusation.
Can I check my full dissertation, or just a part of it?
You can check your entire dissertation, thesis, or essay. There is no word limit — our system is built specifically for long academic documents.
Is my document safe? Will it be stored or shared?
100%. Your work is used only once — to generate your report. It is never uploaded to any public or student database and is permanently deleted from our system within 30 days. We never share or sell your work.
How long does it take to receive my report?
Reports are delivered by email within minutes during UK working hours (9am–9pm GMT).
Is this service really free?
You can download a free sample report to see exactly what you'll receive. The full AI + Similarity report for your own document costs £2.99 — a one-time payment, no subscription.
