Does Turnitin Store Submitted Papers?

Turnitin can store submitted papers when they are uploaded through a school assignment or repository submission. That is why students are often careful about where they upload drafts before the final deadline.

School submissions

When a paper is submitted through an official university Turnitin assignment, it may be added to a repository depending on the institution's settings.

If stored, future submissions can be compared against it.

Pre-check mode

A pre-check should not add your paper to Turnitin's comparison database. This matters because students often want to check a draft before submitting the final version to school.

TurnitinPass uses detection mode rather than repository submission mode, so your paper is not added to the Turnitin database.

Why this matters

If a draft is stored before your final submission, it may create a similarity match against your own work later. Always use a service that clearly states whether uploaded papers are stored.
