Admissions officers have read thousands of essays. After 2023, they started reading thousands of essays that all sounded the same. The same polished-but-empty sentences. The same vague life lessons. The same strange love of em dashes.
If your essay reads like it was written by a chatbot, it doesn't matter whether you actually used one. The problem is the same: you sound like everyone else. And the whole point of a college essay is to sound like you.
This guide will help you spot the patterns that make writing feel AI-generated, then fix them while keeping your own voice intact.
Why AI-sounding essays are a problem (even if you didn't use AI)
Here's the thing most students miss: you don't have to use ChatGPT for your essay to sound like ChatGPT. Years of reading "good writing" examples, five-paragraph essay training, and SAT prep can push anyone toward the same generic style that AI models learned from.
Admissions teams at schools like Stanford and MIT have publicly said they're watching for AI-generated applications. But the deeper issue isn't detection software. It's that AI-sounding writing is boring. It lacks the rough edges, weird specifics, and honest moments that make an essay memorable.
An essay that reads "I learned the value of perseverance through my experience on the varsity soccer team" could have been written by anyone. Or anything. That's the problem.
The AI tells: what makes writing sound like ChatGPT
You can train yourself to spot these patterns in your own drafts. Once you see them, they're hard to unsee.
Vague, inspirational language
ChatGPT loves to wrap things up with a neat bow. Phrases like "this experience taught me the importance of resilience" or "I grew as a person and a leader" sound clean but say nothing specific.
Real essays get messy. They talk about the specific Tuesday when you burned the risotto during your cooking class final and cried in the walk-in fridge. Details like that can't be faked.
Em dashes everywhere
This is the most reliable AI tell in existence. If your essay has more than one em dash, you probably over-edited with AI tools or absorbed the habit from reading AI output. Swap them out. Use a period. Use a comma. Use parentheses. Your English teacher won't mind.
Perfect parallel structure
"Not only did I learn to code, but I also learned to collaborate, communicate, and create." That sentence is technically fine. It's also the kind of thing AI produces on autopilot because it was trained on a mountain of persuasive writing samples.
Real student writing doesn't always balance so neatly. And that's a good thing.
The thesaurus problem
If you normally say "use" but your essay says "utilize," that's a red flag. Same with words like "delve," "foster," "facilitate," "leverage," and "underscore." These show up constantly in AI output and almost never in how 17-year-olds talk.
Write with words you'd actually say out loud. If you wouldn't tell your friend "I leveraged my bilingual upbringing to navigate cultural complexities," don't write it in your essay either.
Starting with "In today's..." or "In a world where..."
These openers are so overused by AI that admissions officers have started calling them out on forums and social media. If your first sentence could apply to any essay on any topic, it's not doing its job.
How to make your essay sound like you
Spotting the problems is the first step. Here's how to fix them.
Start with a specific moment
Don't open with a theme. Open with a scene. Where were you? What were you doing? What did you see, hear, or feel?
"The fluorescent lights in the animal shelter buzzed at a frequency that made my left eye twitch" tells the reader more about you in one sentence than "Volunteering taught me compassion" does in an entire paragraph.
Read it out loud
This is the oldest writing advice in the world, and it still works better than any editing tool. If a sentence makes you stumble or sounds like something you'd never say in conversation, rewrite it.
Your essay should sound like the best version of how you actually talk. Not like a TED Talk transcript. Not like a LinkedIn post. Like you, with the rambling trimmed.
Keep your weird details
The things that make you cringe a little are often the things that make your essay great. The fact that you organize your bookshelf by color instead of author. The way your grandmother calls every dog "that guy." The specific shade of brown your first pottery attempt turned out.
AI can't generate these details because they don't exist in training data. They exist in your life. Use them.
Use contractions
"I am" vs. "I'm." "Do not" vs. "don't." "Cannot" vs. "can't." Formal writing avoids contractions. Human writing uses them constantly. Your college essay isn't a legal brief. Write like a person.
Let some sentences be short
Not everything needs a subordinate clause. Short sentences create rhythm. They also signal confidence: you said what you meant and stopped.
Get a second opinion from a real person
Before you submit, have someone who knows you read the essay. Ask them one question: "Does this sound like me?" If they hesitate, something's off.
Where writing tools actually help (without replacing your voice)
There's a difference between a tool that writes for you and a tool that improves what you've already written.
ChatGPT, when you paste in an essay and say "make this better," will rewrite it in its own voice. That's the opposite of what a college essay needs. You'll get polished output, but the "you" will be gone.
A better approach: write your draft yourself, rough edges and all. Then use a tool that fixes surface-level issues (spelling, grammar, clarity) without touching your voice.
WindowSill is built for exactly this workflow. It's a command bar with a writing assistant that lives on your desktop and works inside any app, including Notion, Word, or wherever you're drafting your essay. Select your text, hit a keyboard shortcut, and pick what you need:
- Spell Check catches typos without rewriting your sentences.
- Improve Text cleans up awkward phrasing while keeping your words.
- Change Tone adjusts formality (say, from casual to professional) without stripping your personality.
- Humanize takes text that sounds too stiff or AI-generated and makes it read more naturally.
- Simplify Language helps if you've fallen into the thesaurus trap and want to bring things back to plain English.
The key difference: WindowSill works on your writing. It doesn't replace it. You stay in control of every sentence, and your voice stays yours.
You can try WindowSill for free on Windows.
Frequently asked questions
Can admissions officers tell if I used ChatGPT?
Not with certainty, and AI detection tools are notoriously unreliable. But that's not the real risk. The real risk is that your essay sounds generic and forgettable because it follows AI patterns, whether or not you used AI to write it.
Is it cheating to use any AI tool on my college essay?
It depends on the tool and how you use it. Pasting your essay into ChatGPT and asking it to rewrite the whole thing? Most schools would consider that dishonest. Using a tool to catch spelling errors or fix a confusing sentence? That's no different from using spell check in Word. The line is whether the ideas and voice are still yours.
What if English isn't my first language?
Your multilingual background is an asset, not a weakness. Write in your natural voice first, then use tools for spelling and phrasing corrections. Don't let a tool smooth out the patterns that make your English unique. Admissions officers value authenticity over perfection.
How do I know if my essay sounds like AI?
Read it out loud. If it sounds like a motivational poster, if every paragraph wraps up with a clean lesson, or if you spot words you'd never use in conversation, those are signs. You can also ask a friend: "Does this sound like me or like a robot?"
Your college essay is one of the few places in the application where you get to be a person instead of a set of numbers. Don't hand that opportunity to a chatbot. Write it yourself, clean it up with the right tools, and let the admissions office meet the real you.
