AI Detector for Non-Native Writers
If English is not your first language, a detector flag can feel like a verdict on your writing. Usually it is a verdict on uniformity — and uniformity is something you can change without changing your voice.
In short: Detectors do not check whether English is your first language. They measure how predictable a text is and how much its sentences vary. Writing that stays inside a safe, careful register — similar sentence lengths, textbook transitions, few idioms — can look more uniform than average, and uniform text scores higher. DeAIze shows which sentences carry that signal, rewrites them, keeps a rewrite only when semantic similarity says your meaning survived, and re-scores the document. A score is a probability estimate, not a statement about you.
Uniformity, not nationality
The detector measures rhythm and predictability. Nothing in the score reads a passport.
See the sentence, not the verdict
Every sentence is highlighted, so you can tell which lines read flat and which already sound like you.
Your meaning is checked, not assumed
A rewrite is kept only when semantic similarity confirms it still says what you meant. Otherwise it is discarded.
Fix the rhythm, keep the vocabulary
Humanizing changes sentence shape and stock transitions. It does not tell you to write in simpler English.
| Rewrite move | What it changes | What to watch for |
|---|---|---|
| Split a long sentence in two | Sentence-length variance, the main signal detectors measure | Do not make every sentence short — that is its own kind of uniformity |
| Change how sentences begin | Repeated openings, a common machine-writing tell | Keep the emphasis on the clause that deserves it |
| Replace stock transitions | "Moreover", "Furthermore", "It is important to note" | Keep enough signposting that a reader can still follow the argument |
| Add one concrete specific | Predictability: a real example is hard to guess | Only details that are true and yours — never invented ones |
| Keep your own phrasing where it works | Voice. Your English is part of the writing, not a defect in it | Reject any rewrite that quietly changes your meaning |
Why uniform prose reads as machine prose
A detector estimates two things: how surprising each word is in context, and how much a text varies in shape. Human writing is uneven. It has a fifteen-word sentence followed by a four-word one, an aside, a sudden concrete detail. Machine writing is even, because it is generated by picking likely continuations.
That definition puts non-native writers in an awkward spot without anyone intending it. Careful academic English taught from templates is deliberately even: similar sentence lengths, standard connectors, few contractions, no jokes. It reads as competent, and to a statistical model it also reads as predictable.
The habits that raise a score
A few patterns show up again and again in flagged drafts. Every sentence lands between eighteen and twenty-five words. Paragraphs open the same way: "Firstly", "In addition", "It is important to consider". Claims are hedged into safety — "this may suggest that it could be argued" — which removes the specific, unusual phrasing that makes text hard to predict.
None of this is bad writing in the ordinary sense. It is writing optimized for not being wrong, and that is exactly the shape a detector associates with generated text.
What not to do
Do not add errors on purpose. Deliberate typos and awkward grammar do not change the rhythm a detector measures, and they make the writing worse for every human reader, including the one marking it.
Do not flatten your vocabulary either, and do not translate idioms word for word from your first language to sound less formulaic — that usually produces a sentence that is surprising for the wrong reason. And do not accept a rewrite that changes what you meant just because the score improved. A number is not worth a distorted argument.
Rewriting without flattening your voice
DeAIze detects first and highlights each sentence by AI probability, so you can see the pattern rather than guess at it. The rewrite pass changes sentence shape: it splits long constructions, varies how sentences open, and swaps stock transitions for plain connectors. You can accept the rewrites that sound like you and reject the rest.
Every rewrite has to pass a semantic similarity check before it is kept, which is the safeguard that matters most here. A tool that rewrites freely will happily "improve" a sentence by changing its claim, and in academic or professional writing that is a much bigger problem than a detector score.
Check your draft before you submit it
Run the draft through detection, read the highlighted sentences, and decide which ones actually sound like you. Rewrite those, re-score, and compare. On a long document this is a short pass: the flagged sentences are usually a minority, and the ones that were never flagged keep the voice the piece already had.
Detection is free and needs no account, so you can check a paragraph before you commit to a whole document. If you are working in a Word file, upload the .docx and the rewritten version comes back with fonts, headings, styles and tables preserved. Text is processed per task only and is never used for training or resold.

Frequently Asked Questions
Do detectors flag non-native English speakers more often?
We do not quote figures, and we would be cautious about anyone who does. Mechanically, the two things detectors measure — predictability and sentence-length variance — are both affected by writing that stays inside a narrow, careful register, which template-taught academic English tends to do.
Should I write in simpler English to avoid flags?
No. Simpler vocabulary does not lower a detector score. Sentence rhythm and variation do, and those are independent of how advanced your word choices are.
Will rewriting change what my text says?
It should not. DeAIze keeps a rewrite only when a semantic similarity check confirms the meaning survived, and discards it otherwise.
Can DeAIze guarantee I will not be flagged again?
No. Detectors are probability estimates that vary between tools and between runs, and none of them can establish who wrote a text. DeAIze reduces the uniformity in flagged sentences; it does not promise a particular result.
