Direct answer
To check a document for AI, you run it through an AI writing detector that analyses prose at sentence level and returns a percentage of qualifying text flagged as AI-generated, alongside highlighted passages you can inspect. Turnitin's detector is built into the similarity report workflow, and the AI writing indicator sits in the report sidebar next to the match overview [1]. The result is a probability signal for review, not a verdict on authorship [1]. Most students checking their own draft want the same report their instructor would see, generated before the final deadline rather than after it.
How Do I Check My Writing for AI Content Before I Submit It?
The practical sequence is straightforward: finish the draft, export it in a format the checker accepts, run the check, then read the report at sentence level rather than staring at the headline number. The AI writing report shows an overall percentage together with sentence-level highlighting of the passages that triggered the detector, so you can see exactly which paragraphs are carrying the signal [2]. That matters more than the total, because a single dense methods paragraph can drive a score that says nothing useful about the rest of the paper.
Only prose is analysed. Reference lists, block quotations, and very short fragments fall outside the qualifying word count, which is why a heavily cited literature review often scores lower than its word count would suggest [2]. The report also separates AI-generated text from AI-paraphrased text in its breakdown, so a draft you wrote yourself and then ran through a paraphrasing tool will not look identical to one generated from a prompt [2]. In institutional accounts the report is usually available within minutes of submission, which is why checking early enough to revise is realistic rather than aspirational [2].
What you do with the result is the part most guides skip. If a handful of sentences are flagged, rewrite them in your own voice, add the specific evidence only you have, and re-check. If a large block is flagged, the problem is structural and a light edit will not fix it. Reading the highlighted sentences first, and the percentage second, keeps the check useful [2].
What Does the AI Score in a Turnitin AI Writing Report Actually Mean?
The percentage is the share of qualifying prose flagged as AI-generated — not the share of the whole document, and not a confidence rating about your intent [3]. A report showing 34% on a 4,000-word essay is saying that roughly a third of the analysed prose matched the detector's AI patterns, with the remainder of the file (references, quotes, tables) excluded from the calculation entirely [3]. Students routinely misread this as "34% of my paper is fake," which is not what the figure reports.
Low-confidence results are displayed differently. When the signal falls below the detector's confidence threshold, Turnitin shows an asterisk in place of an exact percentage, signalling a weak result rather than a precise one [3]. Treat an asterisk as "inconclusive" and look at the highlighted text instead of quoting a number to anyone.
Two boundaries are worth internalising. The score is not a measure of writing quality, and it is not evidence of intent to cheat [3]. Equally, a 0% result does not certify that text is human-written, and a high score is not by itself proof of misconduct [3]. Detectors are probabilistic tools applied to patterns in academic prose, and Turnitin's own guidance frames the indicator as something to be interpreted alongside other evidence rather than acted on alone [1]. That is precisely why a pre-submission check is worth running: it tells you where a reader might raise a question, while you still have time to answer it in the text itself.
Can I Get a Turnitin AI Report on My Own Draft Without Adding It to the Student Paper Database?
Whether a submission enters the paper repository depends on how the assignment is configured, not on the detector itself [4]. Institutional repositories store submitted papers so future submissions can be compared against them, and the repository setting on an assignment determines whether your file becomes part of that comparison set [4]. For a draft you intend to revise and submit again, that distinction matters: a check that files your text into a database can create a self-match later.
Non-repository checking exists for exactly this reason — reviewing a draft without contributing it to the comparison set [4]. Turnitin0's checking service works this way: your file is checked without being added to the student paper database, and reports are not shared with third-party databases, with files deletable from your account. Each order returns two PDFs in one checkout — the AI detection report and the similarity report — mirroring what instructors see in their LMS. Turnitin0 is an independent service and is not affiliated with Turnitin, LLC.
Policy on student previews is set locally, and institutions differ on whether students may run reports themselves [4]. That variation is why the practical answer is to read your own institution's guidance first, then use a preview check to see the report before the stakes are final [4]. Turnitin's own position is that detection should be handled transparently with students rather than as a gotcha, which is an argument for knowing your score early [4].
Reading the report is only half the job — the useful moment is when you can still change the text. Turnitin0 gives you the same AI and similarity PDFs your instructor opens, delivered in under 15 minutes in 98% of cases, so a flagged paragraph becomes a revision task instead of a post-mark explanation.

FAQ
Is checking my own draft for AI allowed?
Many institutions permit student previews, but policy is set locally, so confirm your programme's rules first [4]. Running a check on your own work before submission is generally treated differently from submitting someone else's text.
Why does my report show an asterisk instead of a percentage?
An asterisk appears when the result falls below the detector's confidence threshold, meaning the signal is too weak to report as a precise figure [3]. Read the highlighted passages rather than treating the asterisk as a score.
Does a 0% AI score prove my writing is human?
No. A 0% result does not guarantee human authorship, just as a high score is not proof of misconduct [3]. Detectors are probabilistic, and Turnitin frames the indicator as one piece of evidence among several [1].
Which parts of my document are actually analysed?
Only qualifying prose. Reference lists, quotations, and short fragments are excluded from the word count, so the percentage describes the analysed text rather than the whole file [2].
What should I do if a section is flagged?
Inspect the highlighted sentences, rewrite them with your own specific evidence and phrasing, then re-check the revised draft [2]. If a large block is flagged, revise structurally rather than editing word by word.
