Direct answer
An AI checker can process an Indonesian-language PDF, but it will not give you the same confident verdict it gives on English text — Turnitin's AI writing detection is built into the Similarity Report and was trained primarily on English prose, so Indonesian documents often return a low-confidence signal or an asterisk instead of a number [1]. In practice this means a clean-looking Indonesian report is not proof your draft is safe, and a flagged report is not automatically proof of misconduct [1]. What you can do is preview the same report your institution would see, read the signal honestly, and revise before the deadline rather than after it [1].
Can an AI checker detect AI content in an Indonesian-language PDF?
Detection on Indonesian text is real but weaker than most students expect. Turnitin's AI writing model was trained mainly on English academic prose, so when you submit an Indonesian PDF the model frequently returns a low-confidence result rather than a confident percentage [2]. The report separates text into segments the model marks as detected and segments it marks as not detected, and it highlights only the passages it has enough confidence to score [2].
The practical trap here is reading a low score as a clean bill of health. A near-zero or absent AI percentage on an Indonesian PDF can simply mean the model lacked confidence in that language, not that a human wrote every sentence [2]. Students who submit an Indonesian draft because "the checker said 0%" are relying on an absence of evidence.
The reverse error is just as common. Because the model highlights detected segments rather than judging intent, a flagged Indonesian paragraph may reflect formulaic phrasing, a translated AI passage, or a heavily templated introduction — not deliberate misuse [2]. The report is designed to open a conversation about the writing, and instructors are expected to treat it that way [1]. Your job before submitting is to look at which passages were flagged and ask whether you can rewrite them in your own voice.
Why does Turnitin's AI score show an asterisk (*%) instead of a number?
The asterisk is Turnitin's way of telling you the signal is weak, not that the document is clean. Turnitin displays *% when the AI-writing indicator falls below its 20% confidence threshold, meaning the model does not have enough evidence to commit to a percentage [3]. You will see the same asterisk your instructor sees, so there is no hidden number being withheld from you [3].
That threshold matters most for non-English submissions. Because Indonesian text already produces weaker signals, an Indonesian PDF is more likely than an English one to land in the asterisk zone — low-confidence rather than confidently low [3]. Two different Indonesian drafts can both show *% while carrying very different amounts of AI-generated prose.
So treat *% as "unknown," not "safe." If you know you drafted large sections with ChatGPT, Claude, or Gemini and then translated them into Indonesian, the asterisk tells you nothing reassuring about how a marker will read the text [3]. The honest move is to reduce the AI-shaped prose itself, then re-check, rather than hunting for a checker that will print a friendlier number.
How do I check an Indonesian PDF for AI before I submit it?
Run the check on your actual file, in the format you plan to submit. Turnitin's institutional workflow processes both PDF and DOCX submissions, so an Indonesian PDF exported from your word processor is a valid input — you do not need to convert it back to DOCX first [4]. Reviewing the report before your final deadline lets you revise flagged passages while you still can, instead of discovering the issue after grading [4].
The sequence that works is: finish the draft in Indonesian, export to PDF, run a pre-submission check, then read the report the way a marker would. Look at the AI-writing indicator, the highlighted segments, and the similarity summary together — a passage can be flagged for similarity to a source even when the AI signal is low, and vice versa [4]. Students who only glance at one number tend to misread the whole report.
For a preview that matches the institutional format, turnitin0.com returns a Turnitin AI detection report and a similarity report as downloadable PDFs from a single upload, with an AI score shown as *% when detection sits below the 20% confidence threshold — the same convention Turnitin uses [3]. The service is independent and not affiliated with Turnitin, LLC, and files are checked without being added to Turnitin's student paper database. Turnaround is under 15 minutes in 98% of cases, and 20,000+ students across the US, UK, Canada, Australia, New Zealand, and Ireland have used it, with 100,000+ reports delivered.
If your Indonesian PDF comes back with highlighted segments or an asterisk you cannot interpret, the fastest way to stop guessing is to see the real report before your marker does — that is exactly what turnitin0.com is built for.

FAQ
Does Turnitin detect AI writing in Indonesian text?
Turnitin's AI writing detection is integrated into the Similarity Report, but its model was trained primarily on English prose, so Indonesian documents frequently return a low-confidence signal rather than a firm percentage [1][2]. Detection is possible; confident detection is not guaranteed.
My Indonesian PDF shows *% — does that mean it is AI-free?
No. Turnitin displays *% when the AI indicator falls below its 20% confidence threshold, which signals low confidence rather than a clean document [3]. Treat the asterisk as unknown and look at which passages were highlighted.
Can I check a PDF instead of a DOCX file?
Yes. Turnitin's institutional workflow processes both PDF and DOCX submissions, so an Indonesian PDF exported from your word processor is a valid input for a pre-submission check [4].
What should I do if my Indonesian draft is flagged?
Read the report the way a marker would — AI indicator, highlighted segments, and similarity summary together — then rewrite the flagged passages in your own voice before the deadline [4]. Revising before submission is far easier than explaining a report after grading.
Is turnitin0.com affiliated with Turnitin?
No. Turnitin0.com is an independent service and is not affiliated with Turnitin, LLC. It provides a pre-submission preview of the Turnitin AI detection report and similarity report so students can review their draft before final submission.
