Turnitin AI Detector
Turnitin's AI writing indicator adds a percentage to a Similarity Report and highlights the segments behind it. DeAIze reads the same kind of signal one sentence at a time — then rewrites the sentences that carry it.
In short: Turnitin reports how much of a document its model considers likely AI-written. That figure is a probability estimate, not evidence of who wrote the text. DeAIze scores a document sentence by sentence, rewrites only the flagged sentences, keeps a rewrite only when semantic similarity says the meaning survived, and re-scores the result.
Sentence level, not just a total
Turnitin returns segments and a percentage. DeAIze returns every sentence, highlighted, in an editor you can work in.
A fix, not only a flag
The flagged sentences are rewritten in one click instead of the whole document being reworked by hand.
Meaning checked before it is kept
Each rewrite is gated by semantic similarity, so a lower score never comes from a quietly changed argument.
Word documents stay intact
Upload .docx, .pdf or .txt and get the same formatting back — fonts, styles and tables preserved.
| Aspect | Turnitin AI writing indicator | DeAIze |
|---|---|---|
| What you get | A percentage in the Similarity Report, with the segments it suspects highlighted | An overall score plus a per-sentence breakdown in an editor |
| When it runs | On a submission, as part of the marking workflow | On a draft, before you hand anything in |
| The step after a flag | A conversation with your lecturer about the highlighted passages | Rewrite the flagged sentences, then re-score the document |
| What it proves | Nothing on its own — it is a probability estimate | Nothing on its own — it is a probability estimate |
What Turnitin's AI writing indicator actually reports
Turnitin's AI writing indicator appears inside the Similarity Report rather than as a standalone tool. It adds a percentage alongside the spans of text its model considers likely AI-written, and Turnitin presents the result as an indicator rather than a verdict.
That shape matters when you are reading it. You get one document-level number and the passages behind it, so arguing about the percentage on its own rarely helps. The useful question is which sentences produced it — and what those sentences look like now.
Why the number moves between drafts
Detectors estimate probability from statistical properties of text: how predictable each word is given the words before it, and how much sentence length and structure vary across a passage. Small edits change those properties. The same essay can score differently after a round of proofreading or one rewritten paragraph.
That instability belongs to the method, not to you. It is also the reason a score is best treated as a prompt to look at your draft rather than a conclusion about your honesty.
What to do when your draft comes back flagged
Start with your institution's policy and your lecturer, in that order. Most policies draw a line between using AI to check grammar and having AI produce the argument; the second is usually the problem, and no rewrite tool changes that.
Then read the highlighted passages and ask one question: could you explain this paragraph and defend its sources in person? If the answer is no, the fix is your own writing, not a paraphrase. If a passage is genuinely yours but reads flat — even sentence lengths, stock transitions, no specifics — rewriting it in your own voice is ordinary editing, and it is what DeAIze is built for.
The detect, rewrite, re-score loop
DeAIze detects first: an overall score plus a per-sentence breakdown, with the sentences carrying the AI signal highlighted in red, amber or green. You rewrite those sentences, or let the humanizer propose rewrites, and the document is scored again.
A rewrite is kept only when a semantic similarity check says the meaning survived. That gate is the part that matters. Without it, lowering a score is easy and usually means changing what the text says; with it, you get a lower score on the same argument and a before/after pair of numbers you can compare.
Working from a Word document
Most academic writing arrives as a .docx, so the loop has to survive Word. DeAIze accepts .txt, .docx and .pdf uploads and returns the rewritten document with Word formatting preserved: headings, fonts, styles and tables stay where they were, and you are not rebuilding the file after every pass.
Text is processed per task only. It is never used to train models and never resold, which matters if your institution treats a draft as confidential until it is submitted.
What no detector can promise
Turnitin's indicator, DeAIze's score and every other detector on the market are probability estimates. They disagree with each other, they move when text changes, and none of them can prove who wrote a sentence. DeAIze will not promise you a zero on any detector, and anything that does is worth treating with suspicion.
What DeAIze offers instead is a loop you control: see which sentences look machine-written, rewrite them without losing your argument, and re-check. Where third-party detector APIs are configured, DeAIze cross-checks against those too, so the result does not rest on a single model's opinion.

Frequently Asked Questions
Can DeAIze guarantee a clean Turnitin score?
No, and no tool can. Turnitin's indicator is a probability estimate that shifts with small edits. DeAIze lowers the signal by rewriting the sentences that carry it and then re-scores the document.
Does DeAIze check directly against Turnitin?
Turnitin's AI writing indicator is not offered as a public scoring API. Where third-party detector APIs are configured, DeAIze cross-checks against those; we do not claim a live Turnitin check.
Will rewriting my sentences change my argument?
Every rewrite is gated by a semantic similarity check. If a rewrite drifts from the original meaning it is discarded, so the argument that survives is still yours.
Is rewriting AI-assisted text dishonest?
Passing AI-written work off as your own is. Rewriting your own ideas into clearer, less uniform prose is normal editing. Check your institution's policy and disclose AI assistance wherever it is required.
