Most universities now run AI detection on submitted work. If you've used any AI tools during your writing process — even just for grammar, outlining, or research — it's worth checking your essay before you hand it in.

This isn't about gaming the system. It's about understanding what might trigger scrutiny so you can make sure your submission reflects your own voice.

Why check your own work?

Even if you wrote every word yourself, your essay might trigger AI detection flags:

Grammarly and writing tools standardise your text, making it read more uniformly — which is exactly what AI detectors look for.

Formal academic writing naturally overlaps with AI patterns. Clear structure, balanced arguments, and academic vocabulary all register as potential AI signals.

Research-heavy essays that lean on published sources can read as generic because you're paraphrasing established arguments rather than offering original analysis.

Checking before you submit lets you see what a detector sees, so you can revise flagged sections to sound more like you.

Step 1: Run your essay through a detector

Paste your text into an AI detection tool and look at the results. Pay attention to:

Overall score — is it in the "uncertain" or "likely AI" range?

Flagged passages — which specific sentences or paragraphs triggered the detection?

Patterns — are the same types of sentences being flagged (transitions, conclusions, summaries)?

Is It AI? shows you exactly which passages are flagged and explains why each one triggered detection. That's more useful than a percentage because it tells you what to fix.

Step 2: Understand what got flagged

Common reasons essays get flagged:

Generic introductions. "In today's society, [topic] has become increasingly important." This reads as AI because it is exactly the kind of thing AI writes. Replace it with something specific to your argument or course.

Mechanical transitions. "Furthermore", "Moreover", "Additionally" at the start of every paragraph. Mix up your transitions or remove them — good paragraphs don't always need transition words.

Balanced hedging. "While there are advantages, there are also disadvantages." AI defaults to diplomatic balance. If you have a position, state it directly.

Missing personal voice. No references to your course, lectures, or personal perspective. Add specific examples from your learning — this is something AI can't do.

Step 3: Revise the flagged sections

You don't need to rewrite everything. Focus on the flagged passages:

Add specificity. Replace generic statements with specific examples from your course materials or personal experience.

Vary your sentence structure. Mix short sentences with longer ones. Use fragments occasionally. Write like you talk (within academic norms).

Show your thinking. Instead of stating a point, explain how you arrived at it. "I found this surprising because..." or "This contradicts what we discussed in week 4..."

Cut the filler. If a sentence doesn't add information, remove it. Phrases like "it is important to note that" add nothing.

Step 4: Re-check and submit

After revising, run the essay through the detector again. The flagged passages should be reduced or eliminated. If your score is in the "likely human" range, you're good to go.

If passages are still flagged after revision, consider whether they're genuinely problematic or just formal academic writing that happens to trigger the detector. Not every flag means something is wrong.

What if you did use AI?

If you used ChatGPT or another AI tool to help with your essay, check your university's policy first. Many institutions now allow AI use with disclosure. If you need to declare it, do so — it's much better to disclose upfront than to get caught.

If your institution prohibits AI use and you have used it, the right path is to rewrite the essay from scratch in your own words — not to patch flagged sections. Engage with the material yourself, form your own arguments, and write them in your own voice.

The bottom line

Checking your essay before submission isn't cheating — it's due diligence. You're making sure your writing represents you accurately, that it won't trigger unnecessary investigation, and that you can confidently explain every part of it if asked.
