You’re finishing your thesis. Or you’re preparing a research paper for journal submission. And someone mentions iThenticate.
You’ve heard of Turnitin. But iThenticate? That’s new. And it sounds intimidating.
Here’s the thing: iThenticate is stricter than Turnitin. Journals using it have higher standards. And if you’re planning to publish after graduation, you need to understand what it is and how it differs from student Turnitin.
This guide walks you through everything you need to know about iThenticate. What it is. How it works. Why journals use it. And what you can do about it.
iThenticate is Turnitin’s professional-grade plagiarism and content similarity detection tool.
Think of it this way: Turnitin is built for students checking their theses. iThenticate is built for professionals—researchers, publishers, journal editors—checking published work.
Who uses iThenticate:
The key difference: iThenticate has stricter standards and accesses a much larger database than student Turnitin.
When you submit to a journal that uses iThenticate, your paper gets analyzed against:
1. Billions of Academic Sources
2. Web Content
3. Internal Publisher Repositories
This is a MUCH larger database than Turnitin, which mostly focuses on student papers and some web sources.
The result: iThenticate detects matches that Turnitin might miss because it has access to more published research.
Let me be clear about what this means for you practically.
| Aspect | Turnitin (What You Use Now) | iThenticate (What Journals Use) |
|---|---|---|
| Main users | Students | Researchers, publishers, journals |
| Database size | Moderate (student papers + web) | Massive (all academic sources + web) |
| Similarity tolerance | Under 20% usually acceptable | Under 15% often required |
| AI detection | Basic | Advanced |
| Strictness | Moderate | Very strict |
| False positives | Common | Less common (more refined) |
| Cost | Included in tuition | RM 500-800 per report |
| Used for | Thesis/coursework | Journal submissions, research integrity |
Real example:
Your thesis gets 18% similarity on Turnitin. Your university is fine with it (under 20% threshold).
You graduate. You try to submit the same paper to a journal. They use iThenticate.
iThenticate shows 22% similarity because it found additional academic sources that Turnitin didn’t have access to.
The journal automatically rejects it. Too high.
This happens more often than you’d think.
iThenticate includes what they call “Originality Intelligence”—basically AI detection technology.
What iThenticate’s AI detection looks for:
Why iThenticate’s AI detection is stricter than Turnitin:
Real talk: If your thesis has disclosed AI usage that your university accepted, that same disclosure might get you desk-rejected at a top journal.
Publishers using iThenticate:
If you’re submitting to a journal, check their submission guidelines. They’ll specifically say:
“All submissions are screened using iThenticate plagiarism detection software.”
If you see that, your paper will be checked with iThenticate standards, not student Turnitin standards.
For your thesis (Turnitin):
For journal submission (iThenticate):
What this means practically:
If you’re planning to publish your thesis as a journal article after graduation, you need to:
They’re different standards.
This depends on your plans.
Many universities have iThenticate licenses. Ask your institution if you can check your thesis with iThenticate before submission.
This gives you a preview of how journals will see it.
Cost: Free (if university allows) Timeline: Same day usually Benefit: Know exactly what journal editors will see
Ask your Faculty Office or Institute of Postgraduate Studies (IPS/SPS). Most have access.
Professional editing services can generate official iThenticate reports for you.
PM Proofreading can provide same-day iThenticate reports.
This is useful if you know you’re planning to publish. You can fix issues before submitting to journals.

If you’re just finishing your thesis now:
This is reasonable because: You’re focused on completing your degree. Journal publication is a future concern.
But know this: The humanizing you do for Turnitin also helps with iThenticate. So you’re solving both problems at once.
Here’s the honest truth that nobody tells students:
Universities have accepted AI as an assistive tool. They say “disclose it and keep it under 20%.”
Journals haven’t accepted AI. Many journals say “any AI-generated content = desk rejection.”
Why the difference?
Universities are thinking: “Students are learning. AI is a tool to help them learn.”
Journals are thinking: “This will be published as original research. If it’s AI-written and we publish it, we’re lying to the scientific community.”
Different contexts. Different standards.
What this means for you:
If you disclose AI usage in your thesis and your university accepts it, don’t assume a journal will accept the same disclosure. They won’t.
In fact, some journals have explicit policies: “Any indication of AI-generated content will result in automatic rejection.”
This is especially true for top-tier journals (Scopus Q1, ISI, Nature-tier publications).
If you want to check your work before submitting to journals, you have a few options:
Option 1: Ask the publisher directly
Some publishers will do a screening check for you before you submit. Not all, but some. Call their author support line and ask.
Option 2: Use your institution’s license
If your university has iThenticate access, use it. Most institutions do.
Option 3: Professional report services
Services like PM Proofreading can generate iThenticate reports for you in 2-4 hours (same day).

Option 4: Use Turnitin as a proxy
If you don’t have iThenticate access:
This gives you reasonable confidence without formal iThenticate access.
This is what most researchers do. They don’t check beforehand. They just submit.
What happens:
No explanation. No chance to revise. Just rejected.
How to avoid this:
Check your work with Turnitin (at minimum). Aim for under 15% to be safe.
If you can access iThenticate through your university or via professional service, even better.
Whether you use iThenticate or not, here’s what you need to do:
For your thesis (right now):
For future journal submission (planning ahead):
The humanizing you do for your thesis prepares you for iThenticate later. So doing it right now solves both problems.
Q: Does my university use iThenticate?
A: Probably not for student theses. Most universities use Turnitin for students. But ask your IPS office. Some institutions use iThenticate for final-year projects or research.
Q: Can I get an iThenticate report same day?
A: Yes. Professional services can generate iThenticate reports in 2-4 hours. Get Same-Day iThenticate Report →
Q: Is iThenticate the only tool journals use?
A: No. Some journals use Turnitin, some use iThenticate, some use other tools. Check journal guidelines before submitting.
Q: If I pass Turnitin, will I pass iThenticate?
A: Maybe. Turnitin 18% might be iThenticate 22% because iThenticate has a bigger database. So aim for Turnitin under 15% to be safe.
Q: What if a journal rejects me for high similarity?
A: You can revise and resubmit to a different journal, or fix the issues and resubmit to the same journal if they allow it. But most journals don’t allow resubmission of the same paper.
Q: Should I disclose AI usage to journals like I did with my thesis?
A: No. Different standard. Universities accept AI with disclosure. Journals often reject any AI. Don’t disclose unless asked directly.
Q: How much more expensive is iThenticate than Turnitin?
A: For a single report: iThenticate RM 500-800 vs Turnitin RM 300-500. For institutional licenses, iThenticate costs more.
Q: Can I use iThenticate to check my thesis?
A: Only if your institution has a license and allows it. Ask your faculty office.
For now, focus on getting your Turnitin score under 20% for graduation.
After graduation, if you’re publishing, you can check with iThenticate and get professional iThenticate reports to ensure journal acceptance.
If you need to check your work against iThenticate standards:
