Signs Your Assignment Was Written By AI (and your teacher knows)

AI detection tools have a bad rap. They’re notoriously inaccurate. But seasoned teachers don’t need them to sniff out an AI-written assignment. They have an arsenal of experience on their side to know when their student wrote something themselves or if all they wrote was a prompt.

Despite that, say you wrote a prompt, hit enter, and got the perfect essay in seconds. Yet your teacher still has a feeling. Here’s why:

1. It sounds nothing like you

At the start of the year you wrote: “this character faced many hardships.” While in your newest essay you’re waxing lyrical about how the author has “woven a complex tapestry of human emotion.” You may not realize it, but your teacher knows your voice better than you think.

2. The same fancy words

“Delve into,” “at its core,” and “underscore” are all words and phrases we’ve been seeing a little too often. If words feel like a template, you’d best bet your teacher knows they are.

3. It’s suspiciously balanced

Almost every paragraph mentions the words “on one hand…” and “on the other hand…” Real human-written essays have strong opinions and personal biases that seep through. And no one is trained better to spot them than your teacher, who’s probably read enough student essays before the era of AI to know that the student who supposedly wrote the essay is absent from it entirely.

4. False facts. Unwavering confidence

AI tends to hallucinate facts to fit whatever it’s writing for you. If you’re relying on it for some cold, hard data, then you might get what it thinks you want, not what actually is. Quoting research that doesn’t even exist is a big red flag. And an AI-written assignment has no qualms about that.

5. Perfect grammar… that articulates nothing.

Your essay may have a nice structure and polished sentences, but when it lacks personal anecdotes, local references, or anything that may contextualize it for you and your classroom, then it seems a little too general.

6. It skipped class

Your teacher mentioned specific examples in class that are completely absent from your essay. Coincidence?

7. You can’t explain it

The biggest test: when your teacher asks you about something you supposedly wrote, you fumble.

The point isn’t to get you into trouble, though. Even if you learnt to bypass your teacher’s AI detection skills, what did you actually learn from class? Large language models may make work easier in the immediate sense, but in reality, the more confidence you have in them, the lower your critical thinking skills. And is that a trade-off you’re willing to accept for life?
