Direct answer
Checking a paper on Turnitin means running it through Turnitin's similarity and AI writing detection tools to see how your text matches published sources and how much of it may have been written by AI. A full Turnitin check produces two separate reports — a similarity report and an AI writing report — which are generated independently and viewed from the same assignment screen [1]. For most students, the goal is simple: preview exactly what an instructor would see before a final submission. This guide explains what a check shows, how long it takes, and how to run one on your own draft in advance.
What Does a Turnitin Check Show?
A Turnitin check shows two distinct reports, not a single score. The AI writing report gives an overall AI writing percentage and highlights individual sentences that the detector flags, separating text into "AI generated" and "AI paraphrased" categories [2].
The similarity report works differently: it scans your document against a huge database of web pages, academic journals, and previously submitted student papers, then color-codes matched passages and links each match to its original source [2]. This lets you see exactly which phrases need better paraphrasing or citation before you hand anything in.
Neither report is a judgment of academic misconduct. Turnitin positions both as decision-support tools — the AI percentage reflects the proportion of a document that may have been produced by AI tools, and instructors are expected to interpret it alongside their professional judgment rather than as a standalone verdict [2].
How Long Does a Turnitin Check Take?
For most documents, a Turnitin check is fast. Similarity reports are typically generated within a few minutes of submission, although very large files or periods of high demand can slow the process down [3].
Turnitin's official guidance notes that report generation time depends on file size, document length, and current system load, so a short essay may be processed almost immediately while a lengthy thesis takes noticeably longer [3].
Timing also matters for re-checks: when you edit and resubmit a draft, the system generates an updated report, which is why students who plan multiple revision rounds should leave enough time for each check instead of waiting until the night before a deadline [3].
How Can I Check My Draft on Turnitin Before Submitting?
There are two practical routes to checking a draft before you submit it for grading. If your university enables draft submissions in its learning management system, you can upload a draft and view the similarity and AI reports yourself before the final hand-in [4].
When your course does not offer draft access, the alternative is a pre-submission checking service that runs your file through the official Turnitin system and returns the same two reports an instructor would see — the AI writing report with its overall score and flagged sentences, plus the similarity report with matched sources [4].
Whichever route you choose, the timing advice is the same: check early, review the flagged passages, revise, and check again. A pre-submission check is the only way to know your real numbers before your instructor does, and it turns the report from a surprise into a revision plan [4].
A Turnitin check only helps if the report you see is the real one. turnitin0 runs your document through the actual Turnitin system and delivers the same AI writing and similarity reports that appear in university platforms, with 100,000+ reports already delivered and most results returned in about 10 minutes — so you can check, revise, and re-check with confidence before you ever hit submit.

FAQ
Can I check my paper on Turnitin without submitting it to my instructor?
Yes. If your university does not offer draft submissions, you can use a pre-submission service such as turnitin0, which runs your file through the official Turnitin system and returns both reports privately [4]. The check is performed before any formal submission, so your instructor never sees an unrevised draft.
What does a *% AI score mean on a Turnitin report?
Turnitin displays any AI score below 20% as % rather than as a single-digit number, so a % result means the detector found little to no AI-generated writing. A score of 0% is the only explicit low numeric outcome shown on the report [1].
Does Turnitin store my paper after a check?
When you check through turnitin0, your paper is not archived and is never sent to any third-party database, so your draft stays private. Within your university's own system, storage and retention depend on the settings your instructor has enabled [4].
Is Turnitin AI detection accurate enough to rely on?
Turnitin explicitly advises that AI scores are estimates and should be interpreted with professional judgment rather than used alone to accuse or penalize a student [1]. Use the sentence-level flags to guide your revision instead of treating the percentage as absolute proof.
Should I re-check after editing flagged passages?
Yes. After you revise, run an updated check so you can confirm the flagged sentences are cleared and the overall score has changed before your final submission [3]. This is exactly how a pre-submission check pays off: each round gives you a concrete before-and-after view.
