Paste the key you received by email. It looks like BULK-PLAG100-XXXXXXXX. Once used here, the key is remembered on this device, so you can come back to it any time.
Share single-use links
Each link is worth exactly one check from this key. Give them out instead of the key — cancel any you no longer need and the check comes back.

Bulk Turnitin similarity checks for classes and groups
One Coolsbox bulk key covers 29, 88 or 300 Turnitin similarity checks, from RM2.54 a check — the cheapest way to check a whole class, a research group or a round of assignments. Every check is a real Turnitin similarity report (Old Version, the classic layout) 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
- Pick a pack above and pay. Your key arrives on screen and by email in seconds.
- 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.
- Each report appears in your history on this page, with the similarity score and a PDF to download. A copy is emailed too.
- 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.

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 RM6.99. Checking just one document? A single Turnitin similarity check is RM2.99.
Common questions
Is this the real Turnitin?
Yes. Every check produces an official Turnitin similarity report, the same one your university uses. We run it in non-repository mode so your document is never added to the Turnitin database.
Is this the Old Version or the New Version report?
Bulk packs give the Old Version — the classic Turnitin similarity report. The newest report layout (New Version) is only sold as a single check on the Turnitin Check page, when it is available.
How long does each check take?
Most reports are ready in 2 to 15 minutes. A large batch is processed in order, so the last document in a 100-document batch takes longer than the first — you can close the page, the reports are emailed as they finish.
Can I share the checks with my classmates?
Yes. Generate single-use links and send one to each person. They upload their own file without ever seeing your key, and an unused link can be cancelled to get the check back.
What happens to unused checks when the key expires?
They are lost, so buy the size you will actually use within the validity period shown on each pack (20 days for 29 checks, 25 days for 88, 30 days for 300). Reports are kept for 14 days after each check, so download the PDFs you need.
Do I get an AI writing score?
No — these packs are similarity only. Turnitin's AI writing detection is sold separately as AI + Plagiarism packs.
