Direct answer
An AI detector can flag Paperpal-assisted text, because Turnitin-style detection reads the statistical fingerprint of a passage — word choice, sentence rhythm, and predictability — not the tool that produced it. Paperpal is a legitimate academic writing assistant used for language polishing, restructuring, and drafting support, but text it generates or heavily rewrites can still register as AI-generated prose when it is scanned. Turnitin's AI writing detection runs inside the institutional similarity-report workflow and returns a percentage of qualifying prose flagged as AI-generated, with the triggering sentences highlighted in the report [1]. Because the signal is probabilistic and low-confidence results are shown as *% rather than an exact figure, the only safe way to know where your draft stands is to see the report before your instructor does [1].

Turnitin's AI writing detection runs inside the institutional similarity-report workflow and returns a percentage of qualifying prose flagged as AI-generated, with the triggering sentences highlighted in the report [1]. Because the signal is probabilistic and low-confidence results are shown as *% rather than an exact figure, the only safe way to know where your draft stands is to see the report before your instructor does [1].
Does Turnitin's AI Detector Flag Text Written or Edited With Paperpal?
Yes — Paperpal-assisted text can be flagged, and heavy editing does not automatically remove the signal. Turnitin's AI writing report shows an overall AI percentage alongside sentence-level highlighting, so you can see exactly which passages triggered rather than guessing from a single number [2]. That sentence-level view matters for Paperpal users, because the flagged passages are often the ones where the assistant supplied connective phrasing, transitions, or a rewritten paragraph rather than the parts you wrote from your own notes.
The detector analyses prose only; reference lists, headings, and very short fragments are excluded from the calculation [2]. This is why a Paperpal-polished literature review can come back with a moderate score while a bibliography-heavy appendix stays clean. It also means the score reflects the density of machine-like prose in your body text, not the proportion of your document that touched an AI tool.
Crucially, paraphrasing or editing AI text does not erase detection, because the detector looks at statistical patterns of word choice rather than authorship history [2]. Students often assume that running Paperpal's rewrite over a ChatGPT paragraph makes it "human" — in practice it can simply produce a second layer of predictable phrasing. The report is designed for educator interpretation, not student self-audit, which is precisely why previewing it yourself is the practical move [2].
How Can a Student Check Their Own Draft's AI Score Before Submitting?
Turnitin's own student-facing products do not give you an unrestricted self-check of the AI report — access depends entirely on whether your institution has enabled it [3]. Many students discover this late, after assuming a "check my draft" button exists inside their LMS. Where institutional previews do exist, they are usually limited to a specific assignment and may not show the full AI report at all.
There is also a repository risk that students rarely think about. A draft submitted through an institutional assignment can be retained in the paper database, so a test run is not always as harmless as it looks [3]. That is why non-repository previews are the safer route when you only want to see a score and then keep revising.
Finally, Turnitin advises students to check their course policy on AI assistance before relying on any score at all [3]. Some departments permit Paperpal for language editing but not for drafting; others require disclosure. Knowing the rule first tells you what the number actually means for your submission — a 12% AI score on a permitted editing workflow is a very different situation from 12% on text you asked an assistant to write.
What Should You Do If Your Paperpal-Assisted Draft Comes Back With a High AI Score?
Treat a high score as a revision signal, not a verdict. Turnitin's guidance to students is that flagged passages should be rewritten in your own voice rather than deleted wholesale, and that instructors are instructed to review context before drawing conclusions [4]. The productive response is to open the sentence-level highlights, identify the passages that read as generic, and rebuild those sentences around your own evidence, examples, and reasoning.
Keep your process visible. Drafts, prompts, outlines, and version history are the strongest evidence that the writing is yours, and they are what an academic integrity conversation will actually turn on [4]. A student who can show three drafts moving from bullet notes to a finished argument is in a far stronger position than one who can only produce a final file.
Then reduce the false-positive surface deliberately: add specific citations, replace vague summarising sentences with concrete claims from your sources, and vary sentence length where the prose has gone uniform [4]. Rewriting flagged sentences yourself, with real evidence attached, lowers the machine-like density of the text — which is what the score is actually measuring. If a passage still reads as flagged after two honest revision passes, it usually means the underlying content is too thin, not that the detector is broken.
Knowing your score is only useful if you can see it before the deadline, not after. turnitin0 lets you upload a .docx, .pdf, or .txt draft and receive the same two PDFs your instructor sees — a Turnitin AI detection report and a similarity report — delivered in under 15 minutes in 98% of cases, with no subscription and without adding your file to Turnitin's student paper database. That means you can run a Paperpal-polished chapter through the check, read the sentence-level flags yourself, revise the weak passages, and re-check before anything reaches your module. Over 100,000 reports have been delivered to more than 20,000 students across the US, UK, Canada, Australia, New Zealand, and Ireland, and a single check is $3.80.

FAQ
Is Paperpal considered an AI writing tool by universities?
Paperpal is an AI-assisted academic writing tool, and most institutional policies group it with other generative assistants even when it is used only for language editing. Whether a specific use is permitted depends on your module's policy, so check that before you rely on a score [3].
Can I get a 0% AI score if I used Paperpal?
A 0% result is possible but not guaranteed, because the score depends on how much of your prose carries machine-like patterns rather than on which tool you used. Passages you wrote and revised from your own evidence are the least likely to register [2].
Why does my report show *% instead of a number?
Turnitin displays *% when the AI signal falls below its confidence threshold, meaning the evidence is too weak to report as a precise percentage [1]. Treat it as a low-confidence signal rather than either a clean bill of health or a flag.
Does checking my draft first count as misconduct?
Running a pre-submission check is not the same as submitting to your assignment, and a non-repository check does not add your file to Turnitin's student paper database. The academic integrity question is about how the text was produced, not about whether you previewed the report [4].
Will editing flagged sentences myself fix a high score?
Usually it helps, because rewriting in your own voice with specific evidence reduces the predictable phrasing the detector responds to [4]. If a passage stays flagged, the content is often too general — add concrete claims and citations rather than swapping synonyms.
