Direct answer
Turnitin Self Checker is a tool designed to help students review their drafts for similarity before submitting to their instructors. By running a pre-submission check, students can identify unintentional plagiarism, improve their paraphrasing, and ensure proper citation — all before the final grade is at stake [1]. Understanding what this tool covers, and what it does not cover (such as AI detection scores), is essential for students who want to submit with confidence and maintain academic integrity.
Can Students Use Turnitin to Check Their Own Work Before Submitting?
Yes, but the answer depends on what type of check you mean. Turnitin's Self-Checker lets students upload drafts and receive a similarity report that highlights text matches against the Turnitin database [1]. This helps students spot missing citations or overused sources before the instructor ever sees the paper.
However, the AI writing detection report is a different matter. While similarity previews are available through Self-Checker at many institutions, the AI writing report is typically only visible to the instructor [2]. Students can see their AI writing score only after the instructor releases it — meaning pre-submission AI checking through Turnitin's native tools is not always available [2].
Some institutions have chosen to enable pre-submission AI checking for students, but this is not a universal feature. If your school has not enabled this option, you will not be able to preview your AI detection score through Turnitin's own interface before your final submission [3]. This gap leaves many students unsure about whether their work will be flagged.
What Scores Does a Turnitin Self-Check Show — Similarity, AI, or Both?
A standard Turnitin Self-Checker is primarily focused on similarity scoring. When you run a draft through the Self-Checker, you receive a similarity index percentage that shows how much of your text matches existing sources in Turnitin's database [1]. The report highlights matched passages and provides source links, allowing you to revise citations and paraphrasing accordingly [1].
The AI writing score, which indicates what percentage of your text may have been generated by an AI tool, is not typically included in the Self-Checker preview. Turnitin's AI writing detection report is a separate feature, and most institutions restrict student access to this report until after the official submission and grading process [2]. Students who want to know their AI detection score before submitting often need to seek alternative pre-submission checking options [3].
This distinction is critical: the Self-Checker helps with similarity (plagiarism) concerns, but it generally does not address AI detection concerns. Students who have used AI writing tools — even for legitimate purposes like brainstorming or editing — should be aware that the Self-Checker alone may not reveal how their work will appear in the AI writing report [3].
How Can You Get a Real Turnitin Report Preview Before Your Final Submission?
If your institution does not provide pre-submission access to the full Turnitin report (similarity + AI), you have limited options through Turnitin's own tools. The Self-Checker gives you similarity data, but the AI writing score remains hidden until the instructor releases it [1][3].
One practical approach is to use a trusted third-party service that runs your draft through the same Turnitin detection engine used by universities. These services can provide both the similarity report and the AI writing report, giving you a complete picture before you submit [4]. This allows you to make revisions — whether improving citations or adjusting AI-flagged content — before the official check.
Adopting good academic practices also helps. Review your citations carefully, ensure you have paraphrased properly, and keep a record of your sources [4]. If you have used AI tools for research or editing, review your text critically to ensure your own voice and analysis remain central. Knowing your scores in advance puts you in control of your submission and helps you avoid surprises [4].
Turnitin0 offers a real Turnitin checking service that gives you both the similarity report and the AI writing report — the same reports your instructor sees — before you submit. With over 100,000 reports delivered and 20,000+ students served, you can check your draft in minutes and submit with confidence.

FAQ
Q1: Is Turnitin Self-Checker free for students?
A: Some institutions provide Turnitin Self-Checker access free of charge to enrolled students through their learning management system. Availability depends on your school's Turnitin license. Check with your instructor or library to find out if Self-Checker is enabled for your courses [1].
Q2: Does Turnitin Self-Checker detect AI writing?
A: The standard Turnitin Self-Checker is designed for similarity checking (plagiarism detection), not AI writing detection. The AI writing report is a separate feature that instructors typically control. Most students cannot preview their AI score through the Self-Checker before submission [2][3].
Q3: Can I run my draft through Turnitin multiple times before submitting?
A: Yes, the Self-Checker generally allows multiple submissions so you can revise and recheck your work. However, your institution may set limits on the number of checks per assignment. Each check helps you refine your citations and paraphrasing before the final submission [1].
Q4: What is the difference between a similarity score and an AI writing score?
A: The similarity score measures how much of your text matches existing sources in Turnitin's database (indicating possible plagiarism). The AI writing score estimates the percentage of text that may have been generated by an AI tool. They are two separate reports, and both appear in the Turnitin Feedback Studio [2].
Q5: How can I check both my similarity and AI scores before submitting?
A: If your institution does not offer pre-submission AI checking, you can use a service like Turnitin0 that provides both reports — the same similarity and AI writing reports your instructor sees — before your official submission. This gives you a complete picture so you can make revisions and submit with confidence.
