Direct answer
A Turnitin checking app lets you preview the two reports your professor sees before you submit: the similarity report and the AI writing report. Because Turnitin's AI writing detection displays any score below 20% as an asterisk (*) rather than a single-digit number, many students never see an intermediate score — they only find out how their draft reads when it is too late [1]. Checking your paper in advance turns that uncertainty into concrete evidence you can act on. Here is what to look for in a checking service, whether it is safe to upload your draft, and how to get the real Turnitin report on your paper.
What Should You Look For in a Turnitin Checking App?
The first thing to verify is that the app runs the same AI writing detection model your institution uses. Turnitin's AI writing report identifies the percentage of prose likely generated by AI tools and highlights the specific sentences it flags [2]. A service that only paraphrases the concept of detection, without rendering sentence-level flags, cannot tell you which parts of your paper actually need revision.
Second, confirm the report format matches what instructors see in their academic system. The official AI writing report shows an overall percentage, sentence-level highlights, and the asterisk display for scores below 20% [2]. If a service returns a generic "AI probability" number with no flags or report cover, it is not the report your professor would open.
Third, look for similarity checking in the same delivery. Most students searching for a checking app need both the AI score and the match highlights before submission [2]. A service that bundles the AI report and the similarity summary in one delivery gives you the complete picture instead of a partial one.
Is It Safe to Upload Your Paper to a Turnitin Checking App?
Privacy is the biggest concern when you upload a draft to any third-party service. Turnitin's own guidance emphasizes that AI detection results are one piece of evidence and that institutions control who can view reports [3]. Before you upload, check whether the service stores your paper, whether it shares content with any external database, and who can access the report afterward.
A safe checking service should treat your manuscript as confidential and never add it to a repository that could trigger false similarity matches later [3]. If a third party indexes your words, your own sentences could appear as a similarity match when your professor runs the official check — the opposite of what you want.
Finally, check what happens to your file after the report is generated. Services that keep copies indefinitely, without a clear deletion policy, create unnecessary risk [3]. A trustworthy app should state plainly that papers are not archived and are never sent to third-party databases.
How Can You Get a Real Turnitin AI and Similarity Report for Your Draft?
To see the report your professor would open, the service must run the official Turnitin engine rather than a proxy detector. Students only see Turnitin AI writing results when their institution enables the feature for their class [4]. A checking service that generates the actual report cover, AI score, flags, and similarity summary gives you that institutional view before you submit.
When the report arrives, focus on two numbers: the similarity percentage and the AI writing percentage. If the AI score lands in the asterisk bucket below 20%, the report still tells you that your prose is not clearly flagged [4]. For anything higher, the sentence-level highlights show you exactly what to revise before the official submission.
That is precisely where a pre-submit check changes the outcome. Instead of guessing how your draft will be read, you get the same evidence your instructor would see, and you can decide whether to rewrite, cite more carefully, or humanize flagged passages [4]. The report is yours to keep, and your paper never enters a shared database.
None of that requires a gamble. turnitin0 runs your draft through the real Turnitin engine and returns the exact reports professors see — the AI writing report with sentence-level flags and the similarity summary — so you can verify your score before you submit. Upload your document, review the evidence, and decide with confidence whether your paper is ready or needs revision.

FAQ
What is a Turnitin checking app?
A Turnitin checking app is a service that runs your document through Turnitin's similarity and AI writing detection and returns the reports professors see, before you submit to your institution [1]. It lets you preview your similarity percentage, AI score, flags, and match highlights in advance.
Will using a checking app add my paper to the Turnitin database?
Only if the service stores or redistributes your content. A safe checking service does not archive submitted papers and never sends them to third-party databases, so your own words cannot trigger false similarity matches later [3].
What does the *% AI score mean?
In Turnitin's AI writing report, any score below 20% is displayed as an asterisk (*) instead of a single-digit percentage [1]. The only explicit low numeric outcome students typically see is 0%; otherwise sub-20% results appear as the asterisk bucket.
Can I check both AI score and similarity in one report?
Yes. The full check returns both the AI writing report and the similarity report together, giving you the complete picture your instructor would see [2][4].
How long does a Turnitin check take?
In 99% of cases, results are delivered within 5–10 minutes, and in rare cases within 30 minutes. Most users receive their reports in about 10 minutes.
