How to Make AI-Generated Content Sound More Human

AI hasn’t replaced storytelling — it’s changed who holds the pen.

For centuries, humans have used stories to pass on knowledge, influence culture, and build trust. Today, AI is becoming part of that tradition, helping brands create content faster and at greater scale than ever before. But speed introduces a new challenge: Content that’s technically correct can still feel flat, robotic, or disconnected from real people.

When humans write, we draw from lived experience, emotion, context, and culture. Our language is imperfect on purpose — shaped by nuance, intent, and audience. AI, on the other hand, generates language by predicting what sounds right based on patterns in data. Sometimes that works beautifully. Other times, it misses the mark.

So what does it really mean for AI-generated content to “sound human”? Should it even try? And how do organizations balance efficiency with trust, clarity, and brand integrity?

Key takeaways

• AI-generated content doesn’t need to hide its origins, but it does need to be clear, accurate, and useful to people.
• Human oversight is essential to prevent AI content from becoming unreadable, misleading, or off-brand.
• Content governance is the difference between scalable AI use and inconsistent, risky output.
• Tools like Markup AI help teams humanize AI content while maintaining standards, compliance, and trust.

Why is it important for AI-generated content to sound human?

AI-generated content must sound human to build trust, connect with your audience, and deliver effective communication. When AI-produced writing mimics human tone and nuance, it becomes relatable and resonates with readers. Whether they are customers seeking clarity or professionals engaging with complex information. 

This human-like quality makes sure content aligns with organizational writing goals, maintains consistency, and avoids the robotic tone that alienates audiences. Moreover, in regulated industries like financial services or healthcare, ensuring human clarity and empathy in AI-driven outputs helps meet compliance standards and addresses diverse audience needs​​​.

Can you recognize AI-generated content?

Research suggests that between 30% – 50% of consumers (depending on geographical location) can spot AI-generated copy. But is that a bad thing? Apparently, although half of Americans can tell it’s written by AI, we can’t easily identify any differences in the credibility and trustworthiness compared to human-generated content. And frequently, people even perceive AI-generated content as more engaging, even when they know AI wrote it. 

Research by Markowitz et al. (2024) used a text analysis tool to analyze the difference in hotel reviews written by humans and generative AI. The journal article suggests that AI-generated text sounds more analytical, is more affective, more descriptive, and less readable than a text a person wrote.

Why is that journal article relevant to your enterprise content supply chain? Because search engines primarily reward content that’s designed to give people reliable information. Useful content that’s created for people rather than for search ranking purposes. For content to do the job you intend it to do, it needs to be genuinely useful, sound human, contain accurate information, and be easy to understand.  

The issue with trustworthiness is that just because your readers can’t detect the difference between credible or not doesn’t make it automatically great content. LLMs continue to generate erroneous errors and perpetuate biases. Which is why it’s up to regulatory bodies and enterprises to put AI guardrails in place to make sure that effective content is also ethical. 

Does Google allow AI-generated content?

Yes, Google allows AI-generated content, but with strict guidelines to ensure quality and compliance. The key factor is that the content must be valuable, relevant, and meet the needs of users. Google focuses on the E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) principle, emphasizing the importance of content that provides accurate, trustworthy information regardless of whether it is AI- or human-generated.

Google strongly discourages low-quality, spammy, or misleading AI-produced material. Organizations using AI for content creation must integrate robust oversight and optimization processes to align outputs with Google’s standards and avoid penalties for violating its content policies​​.

How to check AI-generated content before publishing

So how do you make sure your AI-content sounds human, is accurate, and genuinely helpful?

For all the worry about robots taking over the world, they can only do that as much as we hand over our agency to certain technology. So our first tip to making AI-generated content sound human, is to keep humans involved! 

Use AI as a co-writer, not your primary authoring tool. Collaborative writing has been a technique used by multiple content creators as a way to combine skills, knowledge, and creativity to synthesize original content. When one of these contributors is an AI, it changes the dynamics of creation and ideation fundamentally. 

In the meantime, here are more tips to make AI-generated content sound human:

1. Write conversational prompts

The best way to get human-sounding text from an LLM is to speak to it like it’s human. Yes, it’s kind of weird at first. But in this interview with Mollick and Forbes, he sums it up as “treat artificial intelligence like a person, but tell it what kind of a person it is.” meaning you have to get good at prompting in a detailed but conversational way where you’re telling it what to do like it was a person, and correcting it as if it were a person. 

2. Make editing inevitable

In the Markowitz et al., (2024) study, researchers claimed that AI-written text has more positivity bias, more emotive language, and is more linguistically complex, making it less readable. Edit AI-generated text to maintain authenticity and build consumer trust, by making sure your claims are accurate, well-cited, and clear and easy to understand. 

3. Feed tools with your best, most impactful content

AI systems don’t develop taste or judgment on their own — they learn patterns from the material they’re given. If your AI is trained or grounded on generic, outdated, or inconsistent content, its outputs will reflect that.

To improve how AI-generated content sounds and performs:

• Ground your LLMs in your highest-performing content, not your average output
• Use content that reflects your clearest brand voice, strongest structure, and best examples of tone
• Align training inputs with your content style guide, terminology rules, and audience expectations

This ensures AI-generated drafts don’t just sound fluent — they sound like you. Without this grounding, teams spend more time editing AI output than they save by using it.

4. Keep content on-brand with content governance

AI-generated content comes with the risk of publishing content that creates an inconsistent customer experience because it’s not accurate, or doesn’t apply your company’s tone, voice, style, and terminology consistently. That’s why if you want to make AI-generated content production scalable, AI guardrails are non-negotiable. 

5. Use quality gates

As part of your content governance guardrails, set up automated quality gates at different stages of your content supply chain that automatically block off-brand content from ever-being published, and send it back to writers for review.

How does content governance improve AI-generated content?

Content governance provides the structure AI needs to operate safely and effectively at scale.

With governance in place, organizations can:

• Enforce brand voice and tone consistently across human- and AI-generated content.
• Apply terminology and style rules automatically, reducing manual review cycles.
• Prevent non-compliant or low-quality content from being published through quality gates.
• Scale content production confidently without sacrificing clarity or trust.

Platforms like Markup AI embed these rules directly into content workflows, evaluating drafts against predefined standards and providing actionable guidance in real time. This transforms governance from a reactive review process into a proactive quality system — improving user experience while protecting brand integrity.

How Markup AI humanizes AI-generated content

Effective AI content doesn’t come from making machines sound human, it comes from making content sound intentional.

What matters most isn’t whether readers can detect AI involvement, but whether the content is accurate, readable, consistent, and trustworthy. Research already shows audiences respond positively to AI-generated content when it meets those criteria, even when its origin is known.

Markup AI ensures AI-generated content reflects your brand, not a generic model output. Its Content Guardian Agents digitize your style guide and writing standards, applying them consistently across both human- and AI-created content. Every draft is evaluated against the same rules for clarity, tone, terminology, and compliance. This is all done in real-time, within your preferred authoring environment due to an API-first build.

Whether your organization publishes thousands of words or billions, Markup AI helps teams scale content creation without losing control — delivering efficiency gains without compromising standards.

However you tell stories and whoever you want to sound like is your choice. Speak and write like the brand you want to be known for, by your own standards, with Markup AI. Let’s talk to learn more.
