Direct answer
Turnitin's AI detection report is a separate analysis that runs alongside the similarity report, estimating how much of a submission was likely produced by AI writing tools. It gives instructors an overall percentage, sentence-level indicators, and highlighted passages so writing can be reviewed with additional context [1]. For students, learning to read this report is the first step toward knowing how a draft will be judged before it is submitted.
What Is the Turnitin AI Detection Report and What Does It Show?
The AI writing report provides an overall percentage that estimates how much of the text may have been generated by AI, alongside a similarity report that checks writing against existing sources. Instructors see this score in the document viewer with flagged sentences highlighted in the text [2].
One of the most commonly misunderstood details is how low scores are displayed: any AI score below 20% is shown as *% rather than a specific single-digit number, and 0% is the only explicit low numeric outcome students typically see. This display format means a "3%" or "12%" result generally appears as the asterisk bucket instead [2].
Beyond the overall score, the report includes sentence-level indicators that label individual sentences as AI-written, AI-mixed, or human-written, giving both instructors and students a granular view of exactly which passages were flagged. Reviewing these flags alongside the percentage is the most reliable way to interpret what the report is actually telling you [2].
How Does Turnitin Detect AI-Generated Text and How Accurate Is the Detection?
Turnitin's detector is trained on large datasets of human-written and AI-generated text, and it evaluates writing characteristics such as perplexity and burstiness — measures of how predictable and uniform the text is — to estimate the likelihood that a passage was machine-written [3].
No AI detection tool is 100% accurate, and Turnitin itself emphasizes that the report should never be treated as proof of misconduct on its own. The detector can produce false positives, especially with highly structured or formulaic human writing, so results are best interpreted as an indicator rather than a verdict [3].
For this reason, Turnitin advises educators to use the AI report as one piece of context, combined with their own academic judgment and a conversation with the student. Understanding this limitation matters for students too: a flag or score does not automatically mean a paper will be penalized, and it should always be read in full context [3].
How Can Students Check Their Turnitin AI Report Before Submitting?
Students can preview how their writing will look to an instructor by running a draft through a Turnitin-based AI and similarity check before the official submission. This preview shows the same overall score, sentence indicators, and highlights that appear in the instructor's report [4].
Because every revision changes the report, the practical workflow is to check a draft, revise any flagged passages, and check again until the result reflects the writing you actually intend to submit. Re-testing after meaningful edits gives you a clear picture of how the final version will be read [4].
Independent checking services mirror what instructors see in their institutional systems, so a preview before submission removes the guesswork. When you know the score, the flags, and the similarity summary in advance, you can decide whether to revise, rewrite, or submit with confidence [4].
Understanding the report is one thing — seeing your own draft's report is another. Turnitin0 lets you check your paper the way your instructor would, delivering a real Turnitin AI and similarity report on your draft so you can read the score, the flags, and the similarity summary before you ever hit submit.

FAQ
What does the percentage in the Turnitin AI detection report mean?
It estimates the proportion of the submission that may have been written by AI tools. A score of 0% means no AI-written text was detected, while higher scores indicate a greater share of flagged content [2].
Why do I see *% instead of a number in the AI report?
Any AI score below 20% is displayed as *% rather than a specific single-digit percentage, and 0% is the only explicit low numeric outcome students typically see [1].
Can the Turnitin AI detector be wrong?
Yes. No AI detector is perfectly accurate, so Turnitin recommends treating the report as context rather than proof of misconduct and combining it with human judgment [3].
Can I check my own draft before submitting it?
Yes. You can run a draft through a Turnitin-based AI and similarity check before submission to preview the score, flags, and highlights, then revise and re-check until you are comfortable [4].
How long does it take to get a report from Turnitin0?
In 99% of cases, reports are delivered within 5-10 minutes, and delivery is guaranteed within 30 minutes. Turnitin0 has delivered more than 100,000 real Turnitin AI and similarity reports to students worldwide [1].
