How to Use AI in Your Marketing (Without Sounding Like a Robot)

You can smell AI-written marketing from a mile away. Bloodless phrasing, an opener about how busy everyone is these days, and hollow enthusiasm that never lets up. Your audience can smell it too. The moment they do, they stop trusting you. This is how you get the speed of AI without the stench.

The short answer: let AI do the research and the rough drafts, then spin out the variations. A human owns the strategy and the final voice, and checks every fact. Below is how to make that split work day to day, including the exact phrases to delete before anything goes live.

Why AI copy sounds like a robot wrote it

There's no mystery to it. A language model writes by estimating which word is most probable next, based on the text it was trained on. Most probable means most common. So left alone, AI drifts toward the safest phrasing in marketing history, the one a thousand other businesses have already published.

That's why every unedited AI draft carries the same fingerprints:

• Throat-clearing openers. A whole paragraph goes by before the point arrives.
• Hedging on everything. Every claim gets softened and every opinion comes with an "on the other hand". No spine.
• Lists of three stacked on lists of three, in a tidy rhythm nobody talks in.
• Big words doing a small word's job. A plain "use" or "help" gets dressed up as something grander.
• Zero specifics. No names, no numbers from your business, no stories. A competitor could paste it onto their own site unchanged.

Your customers don't need to know how a language model works to spot this. They've read enough of it by now that their brain files it under "ad" and scrolls on.

Where AI earns its keep

• Research and synthesis: Summarising reviews, mining forums for the exact words your customers use, digesting a competitor's whole funnel in minutes.
• The ugly first draft: A blank page is expensive. Let AI vomit out a rough version so you have something to cut and reshape.
• Personalisation at scale: Tailoring one core message to a dozen customer segments used to cost more hours than it returned. Now it takes an afternoon.
• Variant testing: Twenty subject lines, fifteen ad hooks, ten CTAs, generated in seconds so you can test which one converts.

Look at what those four share. A human still decides what's good. AI widens the options and you pick.

Research is the most underrated of the four. Paste in fifty of your own reviews and ask for the phrases customers repeat when they describe the problem you solved. Those phrases are gold. Your next customer is typing them into Google and saying them to their partner. Copy built from customer language sounds human because humans said it first.

Where a human has to stay in the seat

The failure mode is treating AI as an autopilot when it should be a co-pilot. Keep a person in control of the parts that carry your credibility.

Let the machine do the typing. Never let it do the thinking.

• The core strategy and offer: What you promise, and to whom, is a judgment call. You can't generate it.
• The final voice: Rewrite every draft in your own cadence. Cut the throat-clearing and add the detail only you have.
• Every fact and claim: AI gets things wrong with total confidence. Ship nothing you haven't verified yourself.

That last one deserves a warning label. OpenAI's own researchers describe hallucinations as "plausible yet incorrect statements" a model produces when it should admit it doesn't know. In your marketing that looks like a statistic pinned to a study nobody ever ran, phrased so smoothly you'll nearly believe it. Publish it under your brand and you've handed a sceptical customer the perfect reason to doubt everything else you say. Regulators won't take "the AI wrote it" as an excuse either. When the US Federal Trade Commission announced a crackdown on deceptive AI claims in 2024, its chair said there is "no AI exemption from the laws on the books". If you can't find the original source yourself, cut the claim.

Strategy is the other non-negotiable. Ask AI to decide your positioning and you get the positioning of everyone who asked the same question. We explain why AI multiplies whatever you feed it in AI won't replace your marketing, it'll scale what you have.

The workflow: from AI draft to human voice

This process keeps the speed and kills the robot. It works for emails and ads as well as it does for landing pages.

1. Brief it like a new hire. Give AI your offer, your audience, your one promise, three examples of your best past writing and the customer phrases you've collected. Garbage brief, garbage draft.
2. Ask for options. "Give me ten opening lines" beats "write me an email". You want raw material to choose from.
3. Pick, then rewrite by hand. Choose the strongest bits and put them in your own words. If you wouldn't say it to a customer across a table, it doesn't go in.
4. Add what only you know. A real story, a mistake you made, a result with a number on it, an opinion your competitors wouldn't dare publish. No model can supply this part.
5. Run the kill list. Search the draft for the robot phrases below and delete every one.
6. Fact-check line by line. Check each number and each name against a source you trust.
7. Read it aloud before it ships. Your ear catches stiffness your eye misses. If you stumble, rewrite it.

The robot-phrase kill list

These phrases are the loudest tells. Cut each one and say the plain thing in its place.

• "In a world where..." Start with the point. Nobody needs the world explained to them.
• "Whether you're a... or a..." Pick who you're talking to. Copy aimed at everyone lands on no one.
• "Unleash", "elevate", "empower", "seamless", "cutting-edge". Swap them for plain verbs and claims you can back with a number.
• "It's not just X, it's Y." AI leans on this crutch constantly. Once is fine. Three times on a page is a signature.
• "We're passionate about..." Everyone says it. Show what you do differently.
• Closing summaries that repeat the whole piece. End on the ask and stop.

A quick test: if a sentence could sit on any competitor's website without changing a word, it's doing no work for you. Rewrite it until only you could have written it. This matters for search too, because generic copy gives ChatGPT nothing worth quoting. We break down the fix in three edits that get your business quoted by ChatGPT.

A worked example: the same email, twice

Take a hypothetical. Say you run a Perth bookkeeping practice and you want an email inviting past clients to book an end of financial year review.

The unedited AI version opens with "Staying on top of your finances has never been more important." It promises "tailored solutions for your unique needs" and signs off with "We look forward to supporting your financial journey." Every word is correct. None of it sounds like you, and none of it gives a busy owner a reason to reply.

Now run the workflow. You feed AI the phrases clients use, like "I just want someone to tell me what to do before June". You ask for ten subject lines and pick the one that sounds like a person. Then you rewrite the body in two short paragraphs. Last year three clients found deductions they'd missed (only if that's true, and checked). You've got eight review slots in the last fortnight of June. Reply "yes" and you'll send times.

Same tool, same fifteen minutes. The first email reads like a template. The second reads like the person who does their books, because that person wrote it.

How to tell if your AI-assisted copy is working

Don't judge it by how polished it looks. Judge it by what people do.

• Replies. For email, the best signal is people writing back. Nobody replies to a template.
• Click-through against your old copy. Run the AI-assisted version against your best human-written one. Keep the winner, even if it took longer to make.
• Unsubscribes and hides. A rise after you switched to AI drafting is a warning that the voice has gone generic.
• What customers say back to you. If prospects quote your lines on sales calls, the copy is landing. If nobody remembers a word you wrote, it isn't.

Give each test enough volume to be readable, change one thing at a time, and write down what you learned. A few months of that gives you a private playbook of what your audience responds to. Hand it to the AI tool as your next brief.

Voice is a strategy decision before it's a style setting

You can't edit your way to a distinctive voice if you don't know what you stand for. Robotic copy is often a symptom. A business that hasn't decided who it's for will sound generic whether a person or ChatGPT writes the words.

So before you worry about prompts, get clear on who you're talking to, what you believe that your competitors don't, and how you'd explain your offer to a friend at a barbecue. That barbecue version is your voice. Write it down, keep examples of it, and feed them to AI every time. If you can't pin it down, your message might be the real problem, and no tool will fix that for you.

The 10x rule

Used well, AI won't replace your marketer. It gives one sharp marketer the output of a small team. The machine handles the volume and the human guards the taste. Together they move far faster than either could alone, and the result still sounds like a person wrote it. Because one did.

That's how we use it at LIQID NOISE across our digital marketing work: AI for speed and range, humans for strategy, voice and truth. If you want marketing that moves at machine speed and still sounds unmistakably like you, build that balance.

Frequently asked questions

How do I make ChatGPT writing sound more human?

Give it better inputs and edit harder. Feed it customer phrases from your own reviews plus a few samples of your writing. Ask for ten options where you'd normally ask for one draft, then rewrite the best bits in your own words and read the result aloud before you publish.

Can customers tell when marketing is written by AI?

Often, yes. They aren't detecting the tool. They're noticing that unedited AI copy is generic and over-polished, with no specifics in it. People have read so much of it that the pattern registers as "ad" and they move on. Copy that carries your own details and your customers' language reads as human however the first draft was made.

What words make writing sound like AI?

The biggest tells are inflated verbs like "unleash", scene-setting openers about the state of the world, one contrast formula repeated down the page, and tidy lists of three everywhere. No single one is banned. Density is the problem. Swap them for plain words and claims you can back up, and the copy sounds like a person again.

Is it OK to use AI to write marketing copy for my business?

Yes, as long as a human owns the result. Use AI to save time on research, drafts and variations. Keep a person responsible for the strategy and the final wording, and have them check every fact. You're accountable for what you publish, no matter what typed the first version.
