Direct answer
Plagramme is a third-party plagiarism-checking service that compares a submitted document against internet sources and its own indexed text database, returning a similarity percentage rather than a Turnitin report [1]. It is a legitimate, real tool, but it is not Turnitin and does not use Turnitin's index, so its score is a rough signal rather than a prediction of what your instructor will see [1][2]. Most students searching for Plagramme are really asking three things: is it trustworthy, does uploading put my paper into a database, and does its score match my university's Turnitin result [2]. This guide answers all three, and shows how to preview the actual report that counts.
What Is Plagramme and Is It a Trustworthy Plagiarism Checker?
Plagramme is a plagiarism-detection platform aimed at students, teachers, and writers, offering free limited checks alongside paid plans, and it markets itself as a cheaper alternative to institutional tools [1]. Its core function is straightforward: it tokenises your text, compares it against web pages and its internal index, and highlights matching passages with a similarity percentage [1]. That makes it genuinely useful as a first-pass sanity check on whether large chunks of your draft were copied from somewhere [2].
Trustworthiness, however, depends on what you are using it for. Turnitin's own documentation is explicit that a similarity percentage is not a plagiarism verdict — it is a measurement of how much text overlaps with sources, and instructors interpret those matches in context, including properly cited quotations [2]. Because Plagramme draws on a different source index than Turnitin, the same document can produce materially different percentages on the two platforms, and neither number is "the truth" on its own [2].
The practical limitation is coverage. Turnitin compares submissions against a repository of student papers, publications, and internet sources that most universities already feed into, which is why its report is the one tied to your grade [2]. A third-party checker cannot see that institutional repository, so a clean Plagramme result does not guarantee a clean Turnitin result [1][2]. Treat Plagramme as a directional hint, not a substitute for the report your school actually runs.
Does Uploading to Plagramme Put My Paper Into a Database?
This is the question that matters most before you upload original work, and the answer depends entirely on the service's terms rather than on how the tool looks. Turnitin's student paper repository exists specifically to store submitted papers so that future submissions can be checked against them, and institutions decide whether their students' work is added [3]. That repository model is powerful for catching cross-cohort copying, but it also means a paper can live on in an index long after the assignment is graded [3].
Turnitin also supports non-repository checking, where a document is compared against existing sources without being added to the student paper database and without being shared onward to third-party databases [3]. That distinction — repository versus non-repository — is the single most important thing to verify before you upload a draft anywhere, including Plagramme [3]. If a checker's terms are vague about retention, deletion, or whether your text becomes part of its index, assume the least favourable reading.
Your safest habit is to read the retention and deletion policy before uploading, and to prefer services that state plainly that your file is not added to a shared student database [3]. If you cannot delete your file afterwards, or the policy is silent on indexing, that is a real risk to your own original work — especially for a dissertation or thesis you may resubmit elsewhere [3]. Understanding this before you click upload is far cheaper than discovering your paper is indexed after the fact.
Can a Plagramme Score Predict My Turnitin Similarity and AI Result?
No — and this is where most students get caught out. Turnitin's AI writing detection reports a percentage of AI-generated text along with a confidence indicator, and it displays an asterisk (*%) instead of an exact figure when detection falls below its 20% confidence threshold [4]. Those low-confidence signals are not the same as a clean "human" verdict, and a third-party tool has no visibility into that confidence model at all [4].
Turnitin also does not publish a checklist of edits that guarantee a lower AI score, because detection works on statistical patterns across the whole document rather than on individual phrases [4]. That means the common strategy of "rewording a few sentences until Plagramme goes green" is not a reliable way to change what Turnitin reports [1][4]. A Plagramme similarity score and a Turnitin AI score are produced by different engines, on different indexes, for different purposes — there is no conversion formula between them [2][4].
The only way to see the result your instructor will see is to run the same class of check before you submit. Turnitin's documentation makes clear that its similarity and AI reports are the artefacts institutions actually review, so previewing that report — rather than a proxy from a different tool — is what removes the guesswork [2][4]. If your Plagramme score made you nervous, the useful next step is not another third-party estimate; it is seeing the real report format, flags, and score bands for your own draft.
If you want certainty instead of a proxy number, turnitin0 lets you preview the actual Turnitin AI and similarity reports before you submit — the same report view your instructor sees, so you can act on real flags rather than guessing from a different engine's score.

FAQ
Is Plagramme the same as Turnitin?
No. Plagramme is an independent third-party checker with its own source index, while Turnitin compares submissions against an institutional repository of student papers, publications, and internet sources [2][3]. The two produce different percentages on the same document, so a Plagramme result is not a Turnitin result [1][2].
Is Plagramme free to use?
Plagramme offers limited free checks alongside paid tiers, but free tiers typically cap word count or the depth of the report [1]. Free access also usually means you should read the data-retention terms carefully before uploading original academic work [3].
Does uploading to Plagramme add my paper to a database?
That depends entirely on Plagramme's own terms, not on the tool's interface. Turnitin distinguishes repository checks, which store papers for future comparison, from non-repository checks, which do not add your file to the student database [3]. Verify the retention and deletion policy before you upload anything you might resubmit later [3].
Why did my Plagramme score differ from my Turnitin similarity score?
Because similarity is measured against different indexes. Turnitin's repository and web index are broader and institution-fed, and Turnitin treats a similarity percentage as a match measurement rather than a plagiarism verdict [2]. Different index, different number — there is no reliable conversion between the two [2][4].
Can Plagramme tell me my Turnitin AI score?
No. Turnitin's AI writing detection uses its own model and confidence threshold, showing *% when detection is below its 20% confidence level, and it does not map to any external tool's output [4]. To see the AI result your instructor will see, you need a Turnitin-based preview rather than a third-party estimate [2][4].
