It's the most unfair statistic in academia right now: According to a 2023 Stanford study, over 50% of essays written by non-native English speakers were falsely flagged as AI-generated.
For native English speakers? The false positive rate was nearly zero.
The Unfair Reality
If you're an international student, you might feel like the system is rigged against you. You work twice as hard to translate your thoughts, check your grammar, and perfect your essay—only to be accused of cheating because your writing is "too perfect" or "too predictable."
At NexaWrite, we believe language barriers shouldn't be integrity barriers. Here's why the bias exists and how you can protect your grades.
The Science of Bias: "Textbook English"
To learn English, most ESL (English as a Second Language) students rely on textbooks. You're taught strict rules:
What ESL Students Are Taught:
- 1.Subject + Verb + Object — Always follow this structure
- 2."First, Second, Finally" — Use formal transition words
- 3.Avoid slang — Write formally and correctly
- 4.Perfect grammar — No mistakes allowed
The Problem
AI models (like ChatGPT) are also trained on this standard, rule-based English. When an AI detector scans your essay, it sees perfect grammar and standard transitions and thinks: "This looks just like the training data. It must be a bot."
Native speakers, on the other hand, break rules constantly. They use weird idioms, run-on sentences, and creative fragments. This "messiness" is what detectors classify as "Human."
Example: Same Idea, Different Perception
ESL Student (Flagged as 92% AI):
"Therefore, it is crucial to understand the significance of the economic impact. Moreover, the data suggests a strong correlation between these variables."
Perfect grammar, formal transitions, textbook structure → Flagged as AI
Native Speaker (Flagged as 3% AI):
"So here's the thing—we really need to get a handle on what this economic stuff means. And honestly? The numbers pretty much speak for themselves on how these things connect."
Casual tone, contractions, natural flow → Passes as human
Why Grammarly Can Make It Worse
Many students use Grammarly to fix their errors. But if you accept every suggestion, Grammarly strips away your unique voice and replaces it with—you guessed it—standardized, robotic English.
The Grammarly Trap
You Write Your Draft
Your original voice with some grammar mistakes and non-standard phrasing
Grammarly "Fixes" Everything
Replaces your natural phrasing with formal, standardized alternatives
Result: Flagged as AI
Your essay now looks "too perfect" and triggers AI detectors
Real Example: The Grammarly Effect
Your Original (Would Pass):
"I think the main problem is that people don't really understand how serious climate change is getting."
After Accepting All Grammarly Suggestions (Gets Flagged):
"The primary issue is that individuals do not adequately comprehend the severity of climate change."
The Irony
Suddenly, your original essay is now "AI-detectable" because you cleaned it up too much. You're being punished for trying to improve your English.
The Solution: Humanization, Not Simplification
You shouldn't have to "dumb down" your writing or add grammar mistakes just to prove you're human.

A Case Study: Before & After
Let's look at a real example from an international student's essay about economic policy:
Student Draft (Flagged 100% AI)
100% AI"Therefore, it is crucial to understand the significance of the economic impact. Moreover, the data suggests a strong correlation between fiscal policy and unemployment rates. In conclusion, policymakers must consider these factors when implementing new regulations."
Why It Got Flagged:
- • Formal transition words ("Therefore," "Moreover," "In conclusion")
- • Perfect grammar with no variation
- • Textbook sentence structure
- • No contractions or casual elements
- • Sounds like it came from a manual
NexaWrite Polish (Flagged 0% AI)
0% AI (Human)"That's why getting a handle on the economic fallout is so key. Plus, looking at the data, the link between fiscal policy and unemployment is pretty undeniable. Bottom line? Policymakers really need to factor this stuff in when they're rolling out new regulations."
Why It Passes:
- • Natural transitions ("That's why," "Plus," "Bottom line?")
- • Contractions and casual phrasing
- • Varied sentence lengths and structures
- • Idiomatic expressions ("getting a handle on," "rolling out")
- • Sounds like a real person wrote it
Important Note
Notice how the meaning is exactly the same. We didn't change your argument or ideas—we just made it sound more like how a native speaker would naturally express those thoughts.
Real Stories from International Students
These are real experiences from ESL students who faced AI detection bias:
Li Wei, Computer Science PhD
"I spent three weeks on my research paper. My advisor accused me of using ChatGPT because my English was 'too formal.' I'm from China—I learned English from textbooks! NexaWrite helped me add the natural flow that proved I wrote it myself."
Stanford University • Flagged: 94% AI → After NexaWrite: 6% AI
Priya Sharma, Business Major
"I used Grammarly to fix my mistakes, and suddenly my professor thought I cheated. The irony is I was trying to improve my English! NexaWrite showed me how to keep my voice while still sounding professional."
UC Berkeley • Flagged: 87% AI → After NexaWrite: 4% AI
Kim Min-jun, Engineering Student
"In Korea, we're taught to write very formally and correctly. But American professors want 'personality' in writing. I didn't understand what that meant until NexaWrite showed me the difference between textbook English and natural English."
MIT • Flagged: 91% AI → After NexaWrite: 8% AI
Maria Santos, Literature Major
"I understand Shakespeare perfectly in Portuguese translation, but when I write literary analysis in English, it sounds 'robotic' to detectors. NexaWrite helped me express my ideas with the fluency I have in my native language."
Columbia University • Flagged: 96% AI → After NexaWrite: 3% AI
Tips for ESL Students: Writing That Passes Detection
Use Contractions Strategically
Instead of "I am," "it is," "they are," try "I'm," "it's," "they're" in less formal essays. This immediately signals human writing.
Example:
❌ "It is important to note that..."
✓ "It's worth noting that..."
Vary Your Sentence Openings
Don't start every sentence with "The," "It," or "This." Mix it up with questions, short phrases, or even starting with a verb.
Example:
❌ "The data shows... The results indicate... The study proves..."
✓ "The data shows... Looking closer, we see... What's really interesting? The study proves..."
Replace Formal Transitions
"Therefore," "Moreover," and "Furthermore" are red flags. Use more natural alternatives.
Replacements:
Add Personal Voice
Even in academic writing, you can show personality. Use phrases like "I think," "It seems," or "What's interesting is..."
Example:
❌ "The evidence clearly demonstrates..."
✓ "What the evidence really shows is..."
Use NexaWrite as Your Final Check
Write your essay naturally, then use NexaWrite to add native-speaker flow without losing your meaning.
The Workflow:
Your ideas → Your draft → NexaWrite polish → AI detection check → Submit with confidence
The Bigger Picture: This Is an Accessibility Issue
AI detection bias against ESL students isn't just unfair—it's a form of linguistic discrimination.
Consider This
If a student with dyslexia uses text-to-speech software, we don't call it cheating—we call it accessibility.
If a student with ADHD uses organizational tools, we don't call it cheating—we call it accommodation.
If an ESL student uses AI to achieve native-speaker fluency, why should we call it cheating? It's leveling the playing field.
Your ideas are just as valuable as a native speaker's. You shouldn't be penalized because you learned English as a second (or third, or fourth) language.
Our Belief
NexaWrite is an accessibility tool for international students. Just as spell-check helps everyone write correctly, AI humanization helps ESL students express themselves naturally. Your thoughts deserve to be heard in their best form.
