Bulk Turnitin Plagiarism Checks

Bulk Turnitin similarity checks for classes and groups

One Coolsbox bulk key covers 25, 100, 300 or 1000 Turnitin similarity checks, from RM2.33 a check — the cheapest way to check a whole class, a research group or a semester of drafts. Every check is a real Turnitin similarity report run in non-repository mode, so nothing you submit is stored or indexed in the Turnitin database and a later official submission still reads 0% against itself.

How a bulk key works

1. Pick a pack above and pay. Your key arrives on screen and by email in seconds.
2. Paste the key here, then drag in up to 10 documents at a time — repeat as often as you like until the key runs out.
3. Each report appears in your history on this page, with the similarity score and a PDF to download. A copy is emailed too.
4. Need to let classmates upload their own work? Generate single-use links — each one is worth exactly one check, and you can cancel any that are unused.

Who buys these

Course representatives collecting assignments for a class, lecturers and supervisors checking a batch of submissions, thesis and FYP groups at UiTM, UM, UKM, UPM, USM, UTM, UUM, UIAM, UPSI, UNIMAS, UMS, UniMAP and IPG, and writing services that check every draft before delivery. Files may be .docx or .pdf, up to 20,000 words each.

Plagiarism only — no AI writing score

These packs run the similarity check only. If you also need Turnitin's AI writing detection, buy the AI + Plagiarism bulk packs instead, or a single AI + Plagiarism check from RM9.90. Checking just one document? A single Turnitin similarity check is RM2.78.
