AI detection tools look for statistical patterns. But your lecturer doesn't need an algorithm — after reading a few hundred essays, the AI phrases become obvious on sight. The problem is that many of them sound perfectly reasonable when you're writing. They creep in through editing, rephrasing, or just from reading too much academic content online.
Below are the 10 phrases that appear most frequently in AI-generated essays, why each one raises a flag, and — importantly — how to replace them with something that sounds like you actually wrote it.
Run Ctrl+F on your essay and search for each phrase below. If you find any, don't just delete them — replace them with something that serves the same purpose but in your own voice. SafeGrade's Improvement Suggestions and AI Writing Coach can help you rewrite specific passages if you get stuck.
The most flagged AI opener in academic writing. ChatGPT uses it to introduce qualifications or caveats because it's trained on formal text where this phrasing appears constantly. Markers have seen it thousands of times. The passive construction ("it is important") rather than an active voice ("this suggests" or "this matters because") is a giveaway.
Instead, just make the point directly. "This suggests that..." or "Significantly, Bourdieu argues..." or simply cut the opener entirely and lead with the substance. If something is important, your argument should make that clear without announcing it.
Two AI signals merged into one sentence. "Furthermore" as a paragraph opener is overused in AI output, and "it is worth noting" is the same construction as phrase one. Together they're a double flag. If your essay uses "furthermore" more than once or twice, that alone is worth addressing.
Replace with a transition that connects to your actual argument: "This is reinforced by..." or "A related point is that..." or "This connects to...". Alternatively, restructure so you don't need a transition — flow the ideas together directly.
This is AI filler at its most obvious. No student actually writes this. It appears because AI models are trained to provide context before making a point, and this is a stock opener for doing so. The phrase "rapidly evolving" is a particular red flag — it's vague, it says nothing specific, and it appears in AI output across almost every subject area.
Be specific about what's changing and why it matters to your argument: "Since 2020, UK universities have increasingly..." or "The rise of generative AI has shifted how...". Specificity is the cure for AI filler — real observations, real dates, real evidence.
"Delve" alone has become one of the most reliable AI signals in academic text. Its usage frequency in human writing is low; in AI output it's very high. "Multifaceted" has the same problem. Together they're about as clear an AI signature as you can have. If your essay contains either word, remove it.
Just say what you're going to do: "This essay examines..." or "Three dimensions of this issue are...". "Multifaceted" almost always means "complicated" — say complicated, or better still, name the specific dimensions you mean.
AI conclusions are formulaic. They typically restate the essay's main points in a predictable order, and they almost always begin with "in conclusion" or "to conclude." The phrase "it is evident that" is the same passive construction as phrases 1 and 2 — it avoids committing to a voice. Your conclusion should demonstrate judgment, not just summarise.
Start your conclusion with your actual argument: "Bourdieu's framework ultimately explains..." or "This analysis demonstrates that..." or simply with the strongest point you want to leave the reader with. Don't announce that you're concluding — just conclude.
Same passive construction as phrases 1 and 2, used to introduce a new point. The word "crucial" is often used by AI to signal importance without explaining why something is important. It's hedging — the AI is saying a thing matters without actually arguing that it matters.
"This is particularly significant because..." or simply lead with the point itself. If something is crucial, your evidence and analysis should convey that — you shouldn't need to tell the reader it's crucial.
Introduction signposting in this form is something lecturers ask students to do, but AI over-applies it. "This essay will X, Y, and Z" repeated in the intro is a tell — AI introductions tend to list every section of the essay rather than making an argument. The word "critically" is particularly overused; students and AI both add it thinking it sounds more academic.
Signpost, but make it argumentative: "This essay argues that..." or "Drawing on Foucault and Butler, this paper contends that...". Tell the reader what your argument is, not just what topics you'll cover.
A metaphor that AI uses constantly because it appears frequently in academic abstracts and introductions. It's not wrong, but its frequency in AI output has made it a yellow flag. "This research sheds light on," "this essay aims to shed light on" — it reads as filler that sounds scholarly but doesn't commit to saying anything specific.
"This essay explores..." or "This analysis reveals..." or more specifically: "This essay argues that the data reveals a significant gap in...". Precision over metaphor.
"In the realm of education," "in the realm of criminal justice," "in the realm of healthcare" — AI uses this to contextualise points and it sounds vaguely literary. In practice it says nothing. No human academic writes "in the realm of" when they can just write "in education" or "within criminological theory."
Cut it entirely: "Within criminal justice..." or "In social policy..." or simply name the specific context you mean. Three words instead of five, and more precise.
"Moreover" is itself an AI-typical transition (human writers tend to use "also," "additionally," or just structure the argument so it flows without a transition word). Combining it with "it should be noted" — again, the same passive hedge as phrases 1, 2, and 6 — creates a double flag. This is a very common pattern in AI-generated body paragraphs.
"This is further supported by..." or simply restructure: move the point earlier in the paragraph so you don't need a transitional opener. Strong academic paragraphs often don't need transitional phrases at all — the logic carries the reader through.
The pattern behind all of these
Looking at these ten phrases together, a pattern emerges. They're all doing one of three things:
- Announcing importance passively — "it is important to note," "it is crucial to consider," "it should be noted" — instead of demonstrating importance through argument and evidence
- Using vague academic-sounding filler — "rapidly evolving landscape," "multifaceted aspects," "in the realm of" — instead of specific, precise claims
- Following a formula — stock openers, stock transitions, stock conclusions — instead of structure that serves your specific argument
The fix for all of them is the same: be specific, be active, and let your argument do the work rather than announcing that work is happening.
What to do if your essay has several of these
Don't panic — and don't just do a find-and-replace. Mechanically swapping phrases without understanding why they're there usually makes the writing worse, not better.
The best approach is to identify which paragraphs contain the most flagged phrases, then rewrite those paragraphs from the point they're trying to make rather than from the phrase that's in your way. Ask yourself: what is this sentence actually saying? Then say that, in your words, without the filler.
SafeGrade's Improvement Suggestions feature finds AI-typical phrases in your essay and suggests specific rewrites in context — not generic alternatives, but rewrites that consider the sentence around the flagged text. And if you want to talk through a specific passage, the AI Writing Coach (chat icon in the app) can suggest alternatives in your subject's academic style. Both are available free to start.
