Plagiarism and AI Detection Guide – Please read carefully.
Turnitin Plagiarism Check Instruction
For users who purchased the assisted-check service:
Please send the document you want to check to our official email.
Email: turnitinxofficial@gmail.com
We accept Word, PDF, and other common file formats.
Your plagiarism and AI detection report will be delivered to the email you used for purchase within 30 minutes.
For users who perform the check by themselves:
Use the official Turnitin website only:
https://www.turnitin.com/login_page.asp
Next step, enter the account and password sent to your email.
Note: The password includes letters, symbols, and numbers – copy and paste it directly rather than typing it out to avoid errors.
If there is a high word count, or processing speed is slow
The similarity are may show [blank]
Just refresh it after 5 minutes
You MUST refresh or it will remain blank.
If remains blank and there is no response after refreshing
Please contact customer service.
Please wait a few minutes and refresh the page if needed.
Important: You must click on the colored similarity score in order to download the plagiarism report — this step is essential.
If your paper has already been submitted to your university or previously checked for plagiarism, the similarity score may show as 100%.
This is not related to the check conducted through our service.
It simply means your university has archived your submission.
However, the similarity rate does not affect AI detection. The AI check will still function normally and provide accurate results.

If your AI report shows "*% detected as AI", here's what it means:
Your AI detection score falls somewhere between 1% and 19% — for example, it could be 1%, 5%, or 12%.
However, the AI detection system suspects it may be a false positive, which is why it doesn’t display a specific number or highlight it clearly.
If it is indeed a false positive, you can interpret the result as effectively 0% AI content.
Since July 17, the latest version of the AI detection system has adopted this approach — using “*%” as a way to provide more lenient interpretation for scores under 20%, recognizing that AI detectors are not always perfectly accurate.
Unless your institution or journal explicitly requires an AI score of exactly 0%, this range is generally acceptable.
However, the final judgment ultimately depends on your teacher, supervisor, or journal editor.
Please note:
We do not have access to the exact AI percentage behind the “*%” indicator, and neither do the platforms where you submit your paper. The specific score is not visible to anyone.
Why does the AI report extraction link not look “official”?
This website functions more like a tool platform.
It contains an internal instructor account, which uses the Assignment ID you submit to locate and retrieve your AI report.
The AI detection code you receive acts as a key to trigger the report generation.
In other words, the platform acts as a bridge — it accesses the AI detection system on your behalf using instructor-level permissions, then returns the results to you.
AI Detection – Official Platform Limitations
The official AI detection system has specific requirements and limitations:
- Only English or Spanish documents are eligible for AI detection.
-
The word count must be between 320 and 29,999 words.
(Note: This is based on word count, not character count.)
If you receive a message saying AI report retrieval failed, it may be due to one of the following reasons:
- Is your document written in English or Spanish? And is the main body of the text between 320 and 29,999 words?
- Did you submit the paper using the account provided by our support team, and was the Assignment ID generated through that submission?
-
- If not — for example, if you're using someone else’s Assignment ID or an ID from a university submission — the system will not retrieve any report.
- The error message "AI Report Retrieval Failed" often appears if:
-
- The word count is too low or too high
- The content is not in English or Spanish
- The file format is unsupported (e.g., PPT). These conditions will all trigger a failure notice.
Important:
If you modify your content after AI detection, the previous detection result may no longer apply.
We recommend that you run the check again to ensure the AI score still reflects your latest version.
Once you close the browser page, the data will be automatically deleted.
So make sure to download your AI report immediately before closing.
Please don’t ask to retrieve past reports — reports must be downloaded at the time of generation.
Thank you for your understanding!
And that concludes the complete tutorial for Plagiarism and AI Detection!
Below are some common FAQs, we recommend you read till the end!
Question 1:
Why does the similarity rate in our system seem higher/lower compared to the one submitted to the university, especially in relation to the reference list?
Answer:
Our system uses the strictest settings for plagiarism detection — it scans all content, including reference lists and any other sections that might be overlooked elsewhere.
This means the similarity rate on our end may appear higher, but never lower, than what you might see in a university or journal system.
That said, most universities and academic journals do not count the similarity in reference lists toward the final score, as it is widely understood that these are standardized and often similar across papers.
If needed, you may choose to disable the reference list matching option and save the setting, but please note that our default approach is to include everything for the most thorough check.
Question 2:
What the meaning of the highlights with numbers in my plagiarism report?
Answer: For example, 1, 2, 3, 4 — various numbers and colors each represent a different paper. You may have overlaps with many other papers such as those by John, Emily, or David.
The smaller the number, such as 1 or 2, the higher the overlap.
So, (1) is the paper that shares the most similarity with yours, and (2) ranks second in similarity.
3. What are the AI and similarity rate requirements for academic journals?
Journals typically recommend keeping the similarity rate under 10%, and ideally, the AI detection rate should be 0%.
4. Why might my content be flagged as AI-generated?
If you use translation tools such as Google Translate or Youdao, AI writing tools like ChatGPT for polishing, or content generated directly by AI platforms (e.g., Quillbot, Grammarly, etc.), these can increase the chances of being flagged as AI-generated.
5. Why was a section not initially marked as AI, but flagged after I edited the paper?
AI detection is different from plagiarism checking.
-
Plagiarism detection checks for matching content in a database — it highlights the exact sections that match.
-
AI detection evaluates the entire paper holistically, including context, grammar, formatting, wording, and structure.
So even if a sentence or section wasn't initially flagged, once you edit other parts of the paper, the AI model re-evaluates the entire context, and new sections (even previously “safe” ones) may now be flagged as AI-generated.
For example, imagine a student named Alex writes a 1000-word paper with sections A, B, C, D, and E.
After running an AI check, only Section C is flagged.
Alex edits Section C and runs another check. Now, Section C may no longer be flagged — but Section A might be flagged instead, even though it was clean before.
This happens because AI detection only assesses the current version of the full text — it's not tracking past flagged areas. Any modification to format, grammar, or structure can change how the detection algorithm interprets the entire document.
If Alex decides to undo the changes and revert to the original version, the result would return to the initial detection, where only Section C is flagged.
Therefore, it is strongly recommended to run a new AI check after any edits, even if you’ve only made small changes. The risk of your AI score increasing post-edit is very real.
