Direct answer
Yes, Turnitin can show 0% for AI writing, and it is the only explicit low score you are likely to see. Under Turnitin's official display rules, any AI writing score below 20% appears as an asterisk (*%) instead of a specific number such as 3% or 12%, while 0% is shown in full [1]. A 0% result means the detector found no text it considers AI-generated, although instructors still review it alongside the similarity report and other context [1].
What Does the Asterisk (*%) Mean on a Turnitin AI Score?
Turnitin does not show single-digit percentages below 20% in the AI writing report. Instead, scores in that range display as *% [3]. This bucket covers everything from 1% to 19%, so students cannot tell from the report alone whether the underlying result was 5% or 18% [3].
The 0% value is the exception to this display rule. Because 0% is the only explicit low numeric outcome, it carries special meaning for students: a fully clean detection result [3]. Every other low score collapses into the asterisk bucket, which is why "will Turnitin show 0 AI" is a question students genuinely ask.
Instructors see the same display and understand *% as "low likelihood of AI writing." Turnitin's help documentation explains that the asterisk indicates the text is unlikely to have been generated by an AI tool [3]. This nuance matters when reading reports across different drafts and submission dates.
Can a Student Verify Their Own Turnitin AI Score Before Submitting?
Yes — students can and should check their own AI score before submitting the final version. Many universities provide draft-checking access, and independent services that deliver official Turnitin-style reports fill the gap when that access is limited [4]. Running a check beforehand removes the uncertainty of waiting for instructor feedback [4].
A pre-submission check reveals whether the paper lands in the 0%, %, or higher band. If the result is 0% or %, the student can submit with confidence [4]. If the score is elevated, there is still time to revise flagged passages rather than facing a surprise after submission.
Because reports show both the AI percentage and similarity details, a single check gives a complete picture [4]. This mirrors exactly what professors see in institutional systems. Verifying early is the practical way to confirm whether Turnitin will show 0% for your specific paper.
Once you understand how Turnitin displays 0% and % scores, the next step is to see your own report before anyone else does. turnitin0 gives students exactly that: real Turnitin AI and similarity reports on your draft, delivered in minutes, so you know whether your paper lands at 0%, in the % bucket, or in a flagged range — before you submit. No archives, no third-party databases, just a clear preview of what your professor will see.

FAQ
1. Will Turnitin ever show 0% for AI writing?
Yes. When the detector finds no text that appears AI-generated, the report shows 0% [1]. It is the only explicit low value; all other scores below 20% display as *% [3].
2. Does *% mean my paper scored 0%?
No. *% means the score is anywhere below 20%, including values such as 3% or 15% [3]. Only a true 0% displays as "0%".
3. Can my AI score change between checks?
Yes, because detection is probabilistic and wording changes can affect results [2]. Checking the final version of your paper is the most reliable way to know what your instructor will see.
4. Should I check my report before submitting?
Yes. A pre-submission check lets you confirm whether your paper lands at 0%, in the *% bucket, or in a flagged range [4]. This is exactly the preview turnitin0 provides.
5. Is 0% a guarantee my paper won't be flagged?
Not a guarantee, but it signals that no AI-generated text was detected [2]. Instructors still review the full report in context before making any judgment.
