⏳ Typical Turnitin processing times
| Situation | Typical time | Notes |
|---|---|---|
| First submission, normal assignment | 5–10 min | Up to 1 hour at deadline peaks |
| Resubmission 1–3 | 5–10 min | Same as first |
| Resubmission 4 and later | 24 hours | Turnitin's built-in delay |
| Full thesis (40k–65k words) | 15–30 min | More text to match |
| Scanned PDF / images | May never finish | Turnitin needs selectable text |
| Coolsbox automated check | 5–15 min | 24/7, any document, RM2.78 |
🐢 Why Turnitin can be slow
- Deadline peaks. Thousands of students submitting at 11:59 p.m. queue behind each other.
- The 24-hour resubmission rule. From the fourth resubmission, Turnitin waits a day before releasing the report.
- Assignment settings. Lecturers can set reports to generate only on the due date, so you see nothing until then.
- File problems. Scanned PDFs, password-protected files and documents over 800 pages stall.
If you need the score before the official submission, an independent check avoids all of these: upload to Coolsbox, pay RM2.78, and the report is back in 5–15 minutes — with No Repository, so it will not affect your university submission.
❓ FAQ
How long does Turnitin take for a first submission?
Usually 5 to 10 minutes for a normal assignment. Turnitin's own guidance says a first submission can take up to an hour at busy times such as assignment deadlines.
Why does my resubmission take 24 hours?
Turnitin deliberately delays similarity reports for the fourth and later resubmissions of the same assignment by 24 hours, to stop students tweaking text repeatedly. The first three resubmissions are usually quick.
How long for a full thesis?
A 40,000–60,000-word thesis typically takes 15–30 minutes because there is more text to match. Very large PDFs with images take longer still.
Why is my Turnitin report still "processing" after hours?
Common causes: the file is scanned images rather than text, it exceeds Turnitin's size limit (100 MB / 800 pages), the university's Turnitin integration is queued, or the assignment is set to generate reports only on the due date.
How fast is Coolsbox?
5–15 minutes for most documents, 24 hours a day, because the process is automated end to end. You pay RM2.78, upload, and the Turnitin PDF is emailed when it is ready.
