Direct answer
The Turnitin program is the academic integrity suite used by universities worldwide to screen submitted work for similarity and AI-generated writing [1]. If you have ever seen the phrase "submitted to Turnitin," this is the system that produces the originality and AI writing reports your instructors review. This guide explains what the Turnitin program actually does, how its detection engines work, and how you can preview the exact same reports before your assignment is officially submitted.
What Is the Turnitin Program and How Does It Work?
The Turnitin program is not a single checker but a family of tools that universities connect to their learning management systems, including similarity checking, AI writing detection, and feedback and grading features [2]. When a student submits a paper, the program scans the text against a large database of academic papers, web pages, and previously submitted student work, then produces two separate reports: an originality report with a similarity score and an AI writing report that estimates AI involvement [2].
The AI writing report in the Turnitin program analyzes prose to estimate the percentage of text likely generated by AI tools, and it flags specific sentences for review rather than stamping a verdict on the whole paper. Because the program is designed to support instructor judgment, its reports are presented as indicators to be interpreted in context, not as proof of misconduct. Turnitin also publishes detailed guidance on how these indicators should be read, including how to interpret asterisked score bands [2].
For students, the practical takeaway is that the Turnitin program evaluates both borrowed text and machine-written text, and both reports appear before a grade is set. Understanding which part of the program generates which score helps you know exactly what will be reviewed in your submission.
How Does the Turnitin Program Detect Plagiarism and AI-Generated Writing?
Similarity detection in the Turnitin program works by matching submitted text against its content database and reporting the percentage of text that overlaps with existing sources [3]. The similarity report highlights matched passages and links each one to the original source, which is why even properly cited quotations can raise a similarity score when they are lengthy. Plagiarism, in this model, is identified through text matching rather than intent, so the report is a starting point for instructors to review.
AI detection in the Turnitin program uses a different engine that examines writing patterns commonly associated with machine-generated text, such as uniformity in sentence structure and predictability [3]. The program estimates what percentage of the document may have been produced by AI tools and flags those passages in the AI writing report. Turnitin emphasizes that these results are estimates that can produce false positives, and advises instructors to use the report as a discussion tool rather than an accusation [3].
Between the two engines, the Turnitin program gives instructors a fuller picture of how a paper was produced: one report for borrowed text and one for generated text. Knowing this distinction matters because a paper can pass the similarity check and still carry a high AI score, or vice versa.
How Can Students Check Their Turnitin AI and Similarity Scores Before Submitting an Assignment?
The Turnitin program generates its reports after submission, but students can and should see the same information on a draft before the official deadline [4]. Some universities enable draft or re-submission workflows inside Turnitin itself, while many students use third-party checking services that generate the identical AI writing and similarity reports their instructors would see [4]. Previewing your own report lets you fix heavy similarity matches and reduce AI detection risk while you still have time to revise.
When you check early, pay attention to the AI writing report's score band, because the Turnitin program displays any AI score below 20% as an asterisk rather than a single-digit percentage, and 0% is the clearest low outcome [4]. If the report flags a high percentage of AI-written text, revising the flagged passages is the only way to change that number before submission. If the similarity report shows large overlaps, rewriting or tightening citations will bring the score down.
A pre-submission check is essentially a rehearsal of the instructor's review: you see the cover page, the score, the flags, and the similarity summary in the same format used inside institutional systems [4]. That visibility turns the Turnitin program from an unknown risk into a checklist you can act on.
Now that you know how the Turnitin program scores your work, the smartest step is to see your own report before your instructor does. Turnitin0 delivers the exact Turnitin AI and similarity reports that match institutional systems, so you can review the cover, score, flags, and similarity summary on your draft — and revise with confidence instead of guessing.

FAQ
Is the Turnitin program only a plagiarism checker?
No. The Turnitin program bundles similarity checking, AI writing detection, and grading and feedback tools into one academic integrity suite [1].
Can the Turnitin program detect AI-generated text?
Yes. Its AI writing report estimates the percentage of a document likely produced by AI tools and flags the relevant passages for instructor review [2].
What does a *% AI score mean in the Turnitin program?
Any AI score below 20% is displayed as *% rather than as a single-digit number, and 0% is the clearest low outcome students can see [2].
Does the Turnitin program save my paper in its database?
Institutional settings determine whether submissions are stored and compared against future papers, so database retention depends on how your university configures the program [1].
Can I check my Turnitin AI and similarity scores before submitting?
Yes. You can check drafts through your institution's workflow or through services that mirror the exact reports instructors see, allowing you to revise before the official submission [4].
