Direct Answer — Yes, students can check their text on Turnitin before submitting, but only to a limited degree. Turnitin offers a "Check for Originality" button in the Assignment Inbox that allows students to run one similarity check per draft before final submission [1]. However, this feature only returns a similarity percentage — it does not provide a full similarity report with highlighted matches, and it does not include any AI writing detection preview. Furthermore, the feature must be enabled by the instructor, meaning access is not guaranteed for every assignment. For students who need to see both similarity and AI scores before submitting, a third-party service like Turnitin0 fills the gap that Turnitin's built-in tools leave open.
Do Students Have Access to Turnitin Before Submitting to Their Instructor?
Yes — but access is partial and controlled by the instructor. Turnitin's pre-submission check, branded as "Check for Originality," is an optional feature that instructors can enable or disable per assignment [2]. When turned on, students see a "Check for Originality" button in their Assignment Inbox next to each draft file. Clicking it runs a similarity scan against Turnitin's vast database of web pages, academic publications, and previously submitted papers.
There are important limitations to understand. The pre-submission check only provides a similarity percentage — students do not get the full similarity report with color-coded match highlights, source links, or an exclusive view of matched text [2]. Additionally, the feature offers one check per draft; if a student resubmits, they receive another check, but each draft is limited to a single scan. Crucially, the pre-submission check does not include Turnitin's AI writing detection module. So even when an instructor enables "Check for Originality," students cannot preview their AI writing score — a significant blind spot for anyone concerned about false AI flags [2].
The bottom line is that while Turnitin does technically give students pre-submission access, it is restricted to similarity only and depends entirely on instructor settings. Students who want both similarity and AI detection data before submitting have no complete solution within Turnitin's own student-facing tools.
How Can Students Check Their Turnitin AI and Similarity Scores Before Submission?
There are two distinct paths, and they serve different purposes. For similarity scores, students who have the "Check for Originality" feature enabled can get a quick percentage preview through the Assignment Inbox before their final submission [1]. For full reports — including both similarity match details and AI writing detection — students must wait until after the instructor's submission deadline, and only if the instructor has chosen to release those reports [3].
Turnitin's AI writing report, introduced in 2023, shows an overall percentage indicating how much of a submission may have been generated by AI, along with sentence-level highlights of flagged content [3]. However, this report is only visible to students after the final submission is graded or the due date passes, and only when the instructor explicitly grants viewing permission. Before that point, there is simply no built-in mechanism for students to see their AI score [3].
For similarity, the post-submission report (when released) shows a detailed breakdown with matched sources, highlighted passages, and an overall percentage. For AI detection, the report provides the AI score alongside a breakdown by sentence. But again, both of these are post-submission features — not pre-submission previews. This creates a real challenge: students who want to proactively verify their work before the instructor sees it cannot do so through Turnitin's native student interface. They must either rely on the limited similarity-only "Check for Originality" or seek alternative methods to preview their full report in advance.
What Is the Most Reliable Way for Students to Preview Their Turnitin Report Before Final Submission?
Given the limitations of Turnitin's built-in pre-submission tools, students increasingly turn to dedicated third-party services that mirror the institutional Turnitin environment. The most reliable approach is to use a service that processes submissions through the same institutional-grade Turnitin algorithms that universities use — not a generic plagiarism checker that compares against a different database [4].
Turnitin's similarity checker, as the company explains, compares student work against a massive index comprising billions of web pages, hundreds of millions of published academic works, and a repository of previously submitted student papers [4]. A pre-submission preview service must draw from this same index to produce results that match what the instructor will see. Services that use their own proprietary databases or smaller indexes will give misleadingly low or high scores, defeating the purpose of a pre-submission check.
The second critical requirement is AI detection. Since Turnitin's own student-facing pre-submission check does not offer AI detection at all, students need a service that runs the same AI writing detection model that Turnitin applies on the instructor side. Without this, students cannot know whether their draft — especially if AI tools were used for brainstorming, outlining, or editing — will trigger a high AI flag when the instructor receives it.
Turnitin0 addresses both of these requirements by delivering real Turnitin AI and similarity reports — the same format and scoring that instructors see in their academic systems — within approximately 10 minutes of submission. This gives students a true preview of what their instructor will see, enabling them to make informed revisions before the final hand-in.
If you want to know exactly what your instructor will see — before you hit submit — Turnitin0 gives you a real Turnitin AI report and similarity report in about 10 minutes. No subscriptions, no paper archiving, and the same scoring system universities use.

FAQ
Can students run a Turnitin check before the official submission?
Yes, if the instructor has enabled the "Check for Originality" feature in the assignment settings. Students see a button in the Assignment Inbox that runs one similarity scan per draft. However, this check only returns a similarity percentage — not the full report, and not an AI writing score [1].
Does Turnitin's pre-submission check include AI detection?
No. Turnitin's pre-submission "Check for Originality" feature is a similarity/originality check only. It does not run the AI writing detection model, so students cannot see their AI score through this tool [2]. AI reports are only available after the instructor's final submission and at the instructor's discretion [3].
Why can't I see my Turnitin AI score before submitting?
Turnitin intentionally restricts AI writing reports to the instructor side until after submission, and even then only when the instructor chooses to release them. This design means there is no official student-facing AI preview tool [3]. Students who want to know their AI score beforehand must use a third-party service that runs the same detection algorithms.
What is the difference between a similarity score and an AI score?
A similarity score measures how much of a paper matches existing sources (web pages, books, journals, other student papers). An AI score measures how much of the text appears to have been generated by AI tools like ChatGPT or Claude [3]. They are completely separate reports in Turnitin. The pre-submission check offers only similarity; AI detection requires a separate process.
How can I check my Turnitin AI score before my professor does?
Since Turnitin does not offer a student-facing AI preview, the most practical option is a trusted third-party service like Turnitin0, which uses the same institutional Turnitin detection algorithms to generate a preview report. This lets you see both your AI percentage and similarity percentage before your instructor's submission deadline.
