5 ways to make your ChatGPT-generated content undetectable
People think they know when content is AI-generated. The em dash comes under scrutiny almost daily on LinkedIn, with LinkedIn gurus claiming to have spotted the number one culprit that you're using AI to write.
The problem is not em dashes. They have been used in literature for centuries. ChatGPT and other large language models were trained on billions of words from across the internet. Their training data includes em dashes, so the output does too. But em dashes in themselves are not a sign of AI-generated content. The real giveaways run deeper.
Here's how to spot them, and there's what to add to your prompts so you don't fall into the traps.
Real journalists don't use title case. It's marketing speak that invades landing pages and infects tweets. BBC news uses only sentence case. Title case is thoroughly unsystematic, dubbed 'sensationalist case' by those in the know.
AI programs love to use title case and they won't stop unless you tell them to. Most require a comprehensive explanation of what sentence case even means before they'll give it to you. OpenAI CEO Sam Altman knows what's going on. He uses only lower case letters in every tweet. Be less robot and more you.
Add this to your prompt: 'For all headings, sections and subsections, use sentence case instead of title case. In sentence case you only capitalise the first letter of a new sentence, and any proper nouns (no common nouns require capitalisation).'
AI follows patterns. It creates structures you don't see, robotic rhythms you didn't want, and leads your readers down a predictable path. Break away. You need to mix it up and be free.
Follow a proven format, sure. But ad lib within the constraints. Be random, be off-the-wall. Apply perplexity and burstiness. Every now and then, finish a sentence the way no one thought it octopus. Add in words you just made up, let your mind wander, go way off track before you bring it back round to a conclusion. Sometimes, don't even conclude.
Add this to your prompt: "Use varied sentence lengths and complexity for dynamic flow. Avoid predictable patterns. Apply perplexity and burstiness. Mix very short sentences with longer ones. Don't follow formulaic structures. Be unpredictable in word choices."
In the English language, you only capitalise proper nouns. Nothing else. Not seasons, not topics, even job titles don't need capital letters. Real writers know this, but AI tools don't.
Generate a press release or social media post with ChatGPT and you'll spot unnecessary capital letters everywhere. Because it doesn't know the rules. It's making predictions based on its training data, which includes a lot of people getting it wrong. And it's getting worse.
Fix it: 'Only capitalise proper nouns. Not job titles, not seasons, not departments or subjects.'
When you're talking with friends, you don't hedge your words. You don't add fillers before you get to the sauce. AI does. "Quite possibly," "it could be argued," "somewhat," "rather interesting." Real writers make bold statements and back them up. Robots go in gingerly, waiting for approval.
When you're an expert, act like one. Don't apologise for your expertise. Make claims and take stands. Be confident in your knowledge. Don't let AI water you down. Stop qualifying everything you say.
Add this to your prompt: "Be direct and assertive. Avoid hedge words like 'quite,' 'rather,' 'somewhat,' 'it could be argued.' Make bold statements without unnecessary qualifiers."
"In today's fast-paced digital world" might be the most overused phrase at the start of AI-generated content. Right next to "In conclusion, it's clear that" and "At the end of the day" at the end. Cringe city. Pure robot speak, in proud display in LinkedIn posts, blog articles, and marketing emails.
Stop using these terms. Avoid throat-clearing phrases that say nothing. Instead, start your story in the middle of the action. Borrow literary techniques from great filmmakers. Study copywriting formulas that teach you how to hook an audience's attention. Leave them wanting more, not wishing they hadn't bothered.
Add this to your prompt: "Skip generic introductions and conclusions. Start with impact, not setup. End with energy, not summary. Avoid phrases like 'in today's world' or 'in conclusion.'"
Your ideas deserve better than robotic delivery. These prompt additions turn your AI-generated content from obviously artificial to genuinely engaging. Avoid title case, predictable structures, marketing-jargon capital letters, hedge words and generic openings and endings.
Stop worrying about fooling people by using AI. Start producing content you're actually proud of. Content that serves your audience. Content that shares your ethos and strong beliefs. Content that sounds like you.
I don't care if your content is AI-generated. I care if it's good. I care that you have prompted compassionately, so you don't waste my time and everyone else's.
