Direct answer
An aibot check is an AI-detection scan that estimates how much of a piece of writing looks machine-generated, and in a Turnitin context that estimate appears inside the AI writing report as a percentage of qualifying prose text [1]. Turnitin runs this detection alongside the similarity report, evaluates prose only, and requires a submission of at least 300 words before the AI indicator is produced [1]. The percentage is a signal for review, not a verdict, so it should be read together with your draft and your course policy rather than treated as a pass or fail stamp [1].
What Does an Aibot Check Actually Detect in a Turnitin AI Report?
A Turnitin AI report does not label your whole document as "AI" or "human." It highlights the specific segments the model considers likely AI-generated and reports the share of qualifying text those segments represent, so you can see where the signal concentrates rather than just a single headline number [2]. The report is organised into an AI writing overview, the flagged passages themselves, and a similarity layer that sits alongside the AI view, which means you can compare a flagged sentence against any matching source in the same screen [2].
It is equally important to know what the check cannot see. Detection applies to prose only, so tables, images, equations, and other non-prose elements are outside the scope of the indicator, and short submissions under the word threshold never receive an AI score at all [1]. That is why a report can look "clean" while still containing text a marker might question, or look "flagged" in a section you wrote yourself.
Turnitin is also explicit that its detector can produce false positives, particularly on heavily edited writing, formulaic academic phrasing, and text that follows a very regular structure [2]. Reading the flagged segments rather than the headline percentage is therefore the more reliable habit: a segment-level view tells you which sentences triggered the signal, and that is the information you can actually act on [2].
Why Can an Aibot Check Show *% Instead of a Real Percentage?
When Turnitin displays an asterisk in place of a number, it means the AI score fell below the detector's confidence threshold rather than that no AI signal was found. Turnitin shows % when the AI detection result is below its 20% confidence threshold, and those results are treated as low-confidence signals rather than confirmed findings [3]. In practice, % is a "we cannot say this confidently" marker, not a certificate of originality.
This matters because students often misread the asterisk in two opposite directions. Some treat it as proof their draft is safe, while others panic and assume a hidden high score is being withheld. Neither reading matches how the threshold works: the indicator simply sits under the level at which Turnitin is willing to report a number, and the underlying text still carries whatever patterns the model noticed [3].
The practical consequence is that *% should push you toward the same evidence a marker would use. Check the similarity layer, read your own flagged-looking passages, and compare your draft against your institution's AI policy before deciding whether to submit [3]. If you want a number you can actually reason about, you need a report that shows the flagged segments and the score band together rather than an asterisk alone [3].
How Do I Lower My Turnitin AI Score Before Submitting?
The most durable way to reduce an AI signal is to make the writing genuinely yours rather than to disguise it. Rewriting flagged passages in your own voice, adding original analysis and specific examples, and varying sentence rhythm all reduce the regular, predictable patterns that detectors tend to flag [4]. Editing for substance — a sharper argument, a concrete example, a cited source — changes the text in ways that surface-level rewording does not.
Revision also needs to respect academic integrity rules. Turnitin and most institutions recommend that students disclose AI assistance according to their course policy and treat AI output as a draft to be reviewed, not as a final submission [4]. A lower score achieved by hiding AI use is not the same as a lower score achieved by actually doing the thinking, and markers are trained to notice the difference.
Because the AI indicator only covers prose and only appears above the word threshold, the revision work that matters most is at the paragraph level: rewrite the passages that carry your argument, keep your citations and headings intact, and re-check the draft rather than guessing [1][4]. Re-checking after each revision round is what turns a vague worry into a measurable before-and-after, and it is the only way to know whether your edits actually moved the signal [4].
If you would rather see the real report before your deadline than guess at what an asterisk means, turnitin0 gives you the same AI writing and similarity reports your professor sees — delivered in minutes, with the flagged segments and score bands laid out exactly as they appear in an institutional LMS.

FAQ
Is an aibot check the same as a plagiarism check?
No. The similarity report compares your text against sources, while the AI writing indicator estimates how much of your prose looks machine-generated; Turnitin presents them together but they measure different things [1]. A low similarity score does not mean a low AI score.
Does a *% result mean my writing passed?
It means the AI score fell below Turnitin's 20% confidence threshold, so the result is a low-confidence signal rather than a clean pass [3]. Read the flagged segments and your course policy before drawing conclusions.
Can an aibot check flag text I wrote myself?
Yes. Turnitin acknowledges its detector can produce false positives, especially on heavily edited, formulaic, or very regularly structured prose [2]. That is why the report highlights segments for human review instead of issuing a verdict [2].
What is the fastest way to see my real AI score before submitting?
Run a pre-submission check that returns the same AI writing and similarity reports your institution uses, then compare the flagged segments against your draft [2][4]. Turnitin0 delivers both PDFs together, so you can revise with the actual report in hand rather than an asterisk.
How many words do I need before detection runs?
Turnitin only produces an AI indicator for submissions of at least 300 words, and detection covers prose only — not tables, images, or equations [1]. Shorter drafts will not receive an AI score at all.
