How does the plagiarism check work?

You upload your document, and the system compares it against a vast database of academic papers, websites, and publications to generate a similarity report. It also includes AI detection to identify AI-generated content.

What is the No Repository option?

The No Repository option ensures your submitted document is not stored in Turnitin's database, protecting your work from being flagged in future submissions.

How long does it take to get the report?

Reports are typically generated within 3 minutes, and you receive a PDF report via email or download.

Is my submission confidential?

Yes, the service prioritizes confidentiality. With the No Repository option, your document is not stored, and personal information is kept secure.

How much does it cost?

Pricing varies based on document length and service options. Please check the HKAICC website for current pricing and packages.

What is 香港學術誠信檢測中心?

Hong Kong Academic Integrity Detection Center (HKAICC) is an official Turnitin-authorized plagiarism checking service built for Hong Kong students. Users submit a thesis, assignment, or paper and receive a Turnitin similarity report plus an AI-content detection score, delivered as a downloadable PDF. Every submission runs in No Repository mode, so the manuscript is compared against Turnitin's databases but is not written into the student paper repository. A sample report shown on the site displays a 12% similarity figure. Turnaround is typically 3 to 10 minutes, with no need for a university account.

Application scenarios

Pre-submission self-check
Run a paper through Turnitin before uploading it to Moodle, Canvas, or a department portal, so you see the similarity number your instructor will see.
AI-writing risk assessment
Get a separate AI score that estimates whether text was generated by AI, independent of the similarity percentage.
Citation cleanup
Identify whether a high similarity score comes from improper referencing rather than genuine copying, then correct the formatting.
Postgraduate and journal submissions
Check against tighter thresholds — the site notes some research programmes and journal submissions require similarity below 10%.
Group or cohort screening
Students at any of the nine major Hong Kong universities can each run their own check without institutional login.
Rewriting verification
After revising a flagged draft, resubmit to confirm the similarity figure has dropped before the real deadline.
Format and word-count validation
Upload a Word file or paste raw text to get an instant word count and fee estimate before paying.

Core Features

Turnitin similarity checking
Compare your manuscript against the same engine used by over 15,000 educational institutions worldwide, with results presented in a full similarity report.
AI content detection
Receive a dedicated AI score in the report, listed separately from the similarity percentage because the two use different detection mechanisms.
No Repository submission
Submit under No Repository mode so your draft never enters the student paper database and you avoid matching against your own earlier upload.
Large-scale comparison pool
Each check is measured against more than 70 billion web pages and a 190 million student paper database.
Fast PDF reporting
Reports are normally ready in 3 to 10 minutes, extending to roughly 30 minutes during heavy deadline periods or for very long documents.
Flexible input formats
Upload .docx or .doc Word files, or paste body text directly into the page.
Citation format tools
Generate references in APA, MLA, Chicago and other styles to reduce similarity caused by formatting errors.
Similarity safety-line guide
The site publishes reference bands — under 15% is presented as safe, 15%–30% as needing a citation review, and above 30% as warranting a rewrite and re-test.
University-specific policy articles
Guides and updates covering submission rules and similarity expectations across Hong Kong's nine major universities.
Order-based status lookup
Track progress and download your report using the order number issued at payment.
Free academic resource library
Writing guides, citation format instructions, and academic integrity explanations, open to browse at no cost.

Target users

The service targets students at Hong Kong's nine major universities — HKU, CUHK, HKUST, PolyU, CityU, HKBU, Lingnan, EdUHK, and Hong Kong Metropolitan University — and the site organises policy material around those institutions. It fits undergraduates facing a first Turnitin submission, taught postgraduates working to stricter limits, and research students or authors preparing material for journals that demand similarity under 10%. Anyone who wants an independent check before an institutional submission, without registering a school account, is the core user.

How to use 香港學術誠信檢測中心?

Open the checking system on the official site and start a submission.
Upload or paste your text: add a .docx or .doc file, or paste the body text directly. The system calculates word count and cost in real time; the minimum is 1,001 words.
Pay by QR code: the site supports Alipay and WeChat Pay, with the amount shown in Hong Kong dollars.
Wait for comparison: most reports complete in 3–10 minutes; busy deadline periods and long documents can take up to about 30 minutes.
Download your PDF: look up the order with your order number, then download the full similarity report.

Before uploading, the site recommends removing headers, footers, and unrelated attachments so they do not distort the word count.

Effect review

The value here is straightforward: official Turnitin access without an institutional account, paired with No Repository handling that removes the awkward risk of a self-match when the final version is submitted. Running similarity and AI detection as two separate figures is the right call, because a low similarity score says nothing about whether text reads as machine-generated. The 3-to-10-minute turnaround and PDF output make repeat checks practical during a tight revision cycle — you can rewrite, re-upload, and confirm the number moved. The published safety bands and per-university policy articles give students a realistic frame for interpreting results instead of fixating on a single percentage. The main constraint is structural rather than technical: No Repository mode means each re-check is a fresh paid submission, so plan your revision rounds. For students who need a credible, pre-submission read on their own work, the feature set covers the essentials well.
