Which AI Models Does Turnitin Detect? The Named List, and the Gap

Turnitin publishes a list of models its English detector "can detect content from", and the same page says it might miss some AI text. Model names other detector companies are writing about, GPT-6 Astra and Claude Opus 5 among them, do not appear in any of Turnitin's 461 English help articles when we checked on 17 September 2026. Here is the list, the gap, and why neither one predicts what happens to your file.

Does Canvas, Moodle or Blackboard Detect AI by Itself?

The submit button belongs to your LMS, but the AI check, if there is one, usually doesn't. Canvas's own FAQ says AI detection is a service performed by a tool it hands your file to. Blackboard's current manuals describe no feature that checks submissions for AI, though Blackboard launched a writing-process tool in July 2026. Moodle's built-in AI features summarise, explain and generate. What decides it is what your school and your instructor connected.

Pangram vs Turnitin: Why the Two AI Scores Don't Line Up

Where Are the Comments on My Turnitin Report? Reading Instructor Feedback Like a Student

You submitted, the similarity report generated, and your instructor told you the feedback is waiting — but when you open the report you only see match percentages. That is because feedback is a separate layer from the similarity report, and it is only visible after the post date. This article maps Turnitin's own documentation: where the grade sits, what each comment type looks like (bubble, QuickMark, inline, strikethrough, voice), how rubric links show up in a bubble, and how to switch layers so the highlights stop blocking the comments.

What Is My Turnitin Submission ID (Paper ID) and Where Do I Find It?

Every Turnitin submission carries a unique ID, and while it has a different name depending on where you look (Paper ID vs Submission ID), it is the same number.

What Do the Colors on Turnitin's Similarity Report Mean? (Blue, Green, Yellow, Orange, Red)

Your submission shows a yellow icon, your friend's shows green, and someone in the group chat says yellow means trouble. It does not. Turnitin's own documentation maps the five colors to five percentage ranges, and it adds two warnings students rarely hear: the same percentage can wear a different color in a different integration, and the icon only appears once the report exists — a grayed-out icon means "no report yet", not a sixth color. This article walks the official color bands, the SimCheck color swap, and why matched text is not the same as plagiarism.

What File Types Does Turnitin Accept? Supported Formats and the Ones It Won't Check

The upload box rejects your file and gives no explanation. Before you blame the network, check the format: Turnitin's official file-requirements page documents two different rule sets — "allow any file type" only checks size and page count, while "check similarity" also enforces a 20-word minimum and a format whitelist. Apple Pages files, password-protected documents, and image-only PDFs can all clear the size check and still generate nothing worth submitting. This article walks the whitelist, the blacklist, the PDF caveats, and the conversion rules that keep your formatting alive.

How Does Turnitin Detect Collusion? The Due-Date Check Explained (With the Eric & Jane Example)

Your similarity score was 18% before the deadline and 72% two days after — and the report now shows a match against a classmate's paper. Before you panic about being flagged, know what actually happened: Turnitin runs a final peer-to-peer comparison after the due date, so papers that never matched during the term suddenly surface against each other. Turnitin's official documentation describes this mechanism, the Eric & Jane scenario that shows why the copier's score can be the lower one, and the settings that decide whether the check even runs at your institution. This article explains the mechanism, the confusion it creates, and how to respond when your score changes overnight.

Turnitin Draft Coach: Similarity, Citation, and Grammar Checks — The Official Limits

The language question splits into three that get answered as one, and the wrong one usually gets answered first. There is what language the file is in. There is what the detector supports. And there is what happens when you wrote in one language and submitted in another, which is the situation most people asking are actually in.

Does Turnitin detect AI in a PDF?

Most people arrive at this question sideways. The assignment portal wants a PDF, or the journal wants a PDF, and somewhere along the way you start wondering whether the format itself changes what a detector sees. It changes less than you would think, and the things it does change are not the ones being advertised.

Falsely flagged for AI: how to appeal, and what evidence your university will accept

You wrote it. A percentage says otherwise, and now there is a meeting in your calendar. This page covers what to do in the first hour, which evidence has actually persuaded adjudicators in published cases, the arguments that hand the other side a win, and a letter you can copy.

How to humanize AI text without a tool: the edits that actually change the statistics

Turnitin scores overlapping multi-sentence segments, not single sentences. Here is which manual edits target the properties its own documentation names, and what doing the work by hand actually costs.

How to keep version history in Word, Google Docs and Overleaf

An AI detection score is a guess about one finished file. A version history is a dated record of the weeks that produced it. Here is where each tool keeps that record, what the free tiers actually retain, and how to get it out in a form somebody else can open.

Why did Turnitin flag my references?

Two different reports, two different things being measured, and only one of them can put colour on a bibliography. Here is how to tell which one you are holding, why a sentence with a citation in it can still get flagged, and where Turnitin says its own false positives cluster.

Turnitin AI Writing Report vs Similarity Report: do not read the scores as the same thing

The two percentages can appear beside the same submission, but they answer different questions with different evidence. One finds text shared with sources; the other classifies a subset of prose. This guide shows how to read both without turning either number into a verdict.

Turnitin removed the purple AI-paraphrased highlight

The category is gone from the report, not from the model. What changed on 4 August 2026, what a single blue highlight still covers, and why an old screenshot with purple in it is not out of date in the way people assume.

Still flagged after a Turnitin recheck? Compare two reports, not just two scores

A second percentage cannot tell you whether the first revision failed. The document, model and denominator may all have changed. A useful comparison fixes those variables, maps highlights by passage and separates persistent cores from moved boundaries, new flags and report-version effects.

How to review a humanized Word document before submission

Do not proofread the revised file in isolation. Preserve the original, use Word Compare to create a third document, review high-risk meaning changes before style, then update fields and inspect the final pages. The workflow below turns that sequence into a focused 15-minute acceptance check.

Which Harvard referencing style does your university use?

Harvard is a family of author-date styles, not one manual. The correct version is the one named by your assignment, department, institution or publisher. Resolve that authority first, record a five-field specification, then test two real sources before converting the whole document.

How to revise a literature review without breaking the evidence chain

A citation can survive a rewrite while its evidentiary job changes. Sentence splitting, merging and reordering can attach the same author-date marker to a broader, stronger or entirely different claim. Audit claims as units, map each one to a source passage, then check the mapping in both directions.

Methods and results: what you can rephrase and what must stay exact

Revise expression only after separating it from scientific state. Procedures, eligibility, variables, analysis populations, numbers, units, uncertainty and effect direction are invariants. Use the original protocol, code, data and tables as the source of truth; use a study-design checklist to make sure fluent prose has not silently removed required detail.

Final manuscript check: AI disclosure, word count, citations and DOCX integrity

A finished argument is not yet a finished submission. Freeze the journal requirements, classify and disclose actual AI uses, settle the exact word-count scope, then revise, condense and standardize citations in that order. Finish by updating Word objects, producing a clean copy, uploading the complete package and reading the portal-generated PDF before you confirm.

Why non-native English writers get flagged by AI detectors more often

Seven detectors misclassified 61% of a sample of human-written TOEFL essays. The study does not represent every multilingual writer, but its controlled edits show why limited lexical range can move a detector score without changing who wrote the argument.

What AI detectors measure beyond perplexity and burstiness

Perplexity and burstiness explain the first generation of public AI detectors, but they are not authorship tests and they no longer describe the whole system. Modern classifiers add learned signals while leaving the same interpretation problem in place.

The percentage is not the share of your document that is AI. It is the share of one specific subset of it - and knowing which subset explains most of what looks wrong in these reports.

Is 20% AI too high? Why there is no absolute threshold

Twenty percent is Turnitin's boundary for displaying a numerical result, not a universal boundary for misconduct. The meaning of any report depends on qualifying text, model error, the location of highlights and the institution's own rules.

Flagged, but you wrote it yourself: preparing a response

A detector score is not proof by itself. Review cases from England and Wales show why provenance, disclosure of the evidence and a fair chance to respond matter more than a competing score - but the procedure and burden of proof must be checked in your own institution and jurisdiction.

Why Zotero and EndNote exports sometimes miss the required style

A reference can be wrong at three layers: source metadata, item type or style rules. The manager formats what it has, so a polished output may still reproduce a missing author, bad journal abbreviation or outdated local variant perfectly.

Word fields, tables of contents and cross-references: why plain-text round trips break a thesis

A table of contents and many cross-references are live instructions, not ordinary characters. Copying their displayed results through a plain-text tool can make the replacement look correct while silently removing the codes, links and document structure that kept it correct.
