AI and GPTs for proofreading and improve the quality of your content

Struggling to know if your content truly resonates, and what if your content isn’t as great as you think it is? At least 60% of all content is clutter (Havas, 2017); in 2025, this might even be 90% or more. 

Being a bit blindfolded about your own content is very common. Proud of what you just produced, you hit publish. And you forget that you’ll need to check if your content resonates with your audience. 

→ Brutally honest feedback sharpens your message. AI can give you that clarity.

If you want your content to rise above mediocrity with harsh but much-needed feedback, this is for you. It’s like getting feedback from a Dutch: direct, honest, and aimed to improve you.

Why proofreading matters to prevent content from failing

I dare to say that 9 out of 10 articles, blogs, and thought leadership stories are mediocre.

The content is reasoned from within, focused on sending and boosting, and usually sticks to the surface. Or some copy wanders off-topic, trying to showcase expertise or simply fill space.

However, content that makes an impact and brings your message across, content that gets discovered by AI search and ranks well in SEO, is the opposite.

We’re all familiar with how AI can help you with grammar and autocorrect. But have you ever considered using AI to proofread and improve the quality of your content?

Here are 3 powerful ways how you can use AI and GPTs for proofreading

• Use AI to check content structure, logic, and flow: is your key message clear enough
• Let AI check if your content resonates with your audience: is it sexy to read
• Ask AI to find flaws in your reasoning

For the sake of brevity and not wanting to write an operational manual here, I presume you have basic AI and prompting knowledge, and you know how to build GPTs (custom AI assistants in ChatGPT).

Let's dig into how I use AI and GPTs to improve my content quality. 

1. Use AI to check content structure, logic, and flow

This GPT is all about checking the structure and logic of my copy and if it makes sense. It's the first GPT I use after finalizing my draft.

The feedback is harsh and doesn’t spare me. But it’s good and improves my content.

Below are the instructions I use in my GPT. I realize it’s not perfect English, and there are some duplicates in my instructions, but it works very well, and I don’t fix what isn’t broken.

Usually, I run this 3 times. The GPT will always find something and sometimes can contradict itself.

‘Can you proofread without the content, without rewriting or changing my bold and clear tone? Please give suggestions on the structure. Is it clear and logical, or do I need to improve?

Also, give suggestions for better words for headers and subheaders.

Please don't rewrite, but give me your suggestions so I can implement those myself.

Write in B1 intermediate English and optimize for mobile reading with short paragraphs and subheaders.

Let me know where I can improve so the flow of the copy improves and it becomes easier and more fun to read. And again, don't rewrite, give me suggestions and tell me what I need to improve. I want to make the changes myself in my CMS.

The subject line, headlines, or titles should always be formatted in sentence case (never capitalize the first letter of each word because we don't want our subject lines to read like an article headline).’

Note that I ask for suggestions and ask AI not to rewrite my content. I want to cherry-pick and implement the changes myself so my content stays authentic.

Once I’m happy with the structure and logic, I use a GPT to check if it resonates with my audience.

2. Let AI check if your content resonates with your audience

This GPT evaluates my copy from my audience persona, CEO or CMO, perspective. Does it resonate? Is it short, snappy, and sharp enough? Are there any abundant elements to distract or make them click away? 

This GPT makes me kill my darlings instantly.

How to create this GPT in a few steps.

1. Let AI describe your audience persona
   You ask AI to describe your audience persona in the smallest detail. Who are they, what do they like, how do they read, and what’s important to them?
   
   This includes elements such as their profile, preferred content types, and key challenges in their job. It’s like doing market research with AI.
   
    
2. Define what writing style fits your persona
   In my case, this is a ‘writing for busy readers’ style with guiding principles such as 'less is more', 'make it easy to read', 'structure and format for scanning', 'start with the conclusion and what matters'.
   
   I also add to find and point out the fillers, jargon, clichés, adverbs, or buzzwords.
   
   Important note: always open a new chat in ChatGPT to prevent contamination from the audience persona.
    
3. Combine the persona and style in a GPT
   This is where it comes together. My instructions in this GPT are 1,153 words, so I don’t copy-paste it here. But you test It here; ‘Evaluate my copy from the perspective of a CMO or CEO’ 
   
   I usually run this GPT 2 or 3 times. Like with the proofreading GPT, it will always find something and end up contradicting and confusing itself if you run it too many times.

Beside GPTs, you can also use a simple prompt to get feedback and proofread. 

3. Ask AI to find flaws in your reasoning

This is a simple prompt, and no GPT is needed. Again, a little warning: AI is not lighthearted and doesn’t spare you. 

Get criticized by ChatGPT
Let’s start with the easiest prompt with a placeholder for your content. You paste your content or idea on the blank line. 

I want you to act as a critic. Criticize my idea and convince me why they are bad. Let's think step by step. Consider I am a pro, and don't spare me. My idea: _________  

Use roleplay to get roasted by ChatGPT

However, if you make more effort, AI will reward you with much better output. I use the RICE-model for my prompts.

• Roleplay: ‘Act as if you hate me and you are my worst criticaster’
   
• Instructions: ‘Try to find the flaws in my thinking, where my logic or reasoning doesn’t make sense, where I cut corners, or where I might be biased. Use trustworthy sources only for your feedback’
   
• Context: this is where you give a bit more background information. ‘I want to use this writing to convince the CEO to do XYZ. Therefore, it is important that you stick to a strategic level and align your feedback with how it influences the business case and business objectives.’
   
• Examples: if you have any examples, list them here. If you don’t have examples, you can include your tone of voice as the last part of the prompt and how you want the output to look like. ‘Please, use a clean, clear, short, sweet tone of voice, as if I’m your business friend. Don’t use jargon or buzz words. Use bullet lists where possible. As short as possible, as long as needed. B1 intermediate English, reading level 8.’

Try my GPTs 

Please feel free to use my GPTs for your content and experience how AI can give you feedback. 

• GPT to check the structure and logic 
• Evaluate my copy from the perspective of a CMO or CEO 

I can’t see if and what you do with these GPTs. But be aware that these are custom-built for me, my objectives, and my tone of voice.

Frequently asked questions about AI proofreading and GPTs

• Can AI replace human proofreaders?
  
  AI is great for catching many errors and providing structural feedback, but it may not fully replace human proofreaders. Humans best understand the context, cultural nuances, humor, and more complex writing styles.

• Can GPT provide feedback beyond basic grammar and spelling?
  
  Yes, GPT can offer feedback on:
  • Clarity and conciseness
  • Overall tone and style
  • Audience suitability
  • Logical structure and flow
  • Key message effectiveness

• What are the limitations of AI proofreading?
  
  Depending on how you use AI for proofreading and the level of customization of your GPTs,
  • Can struggle with highly technical or niche vocabulary,
  • Has a limited understanding of subtle humor or sarcasm
  • Can’t fully grasp creative intent or emotional tone
  • Might suggest incorrect changes; that’s why you ask for suggestions and not to rewrite
  • Has difficulty correctly interpreting the formatting (H1, H2, bullet lists, etcetera)

AI for proofreading: Your secret weapon for better content

AI is so useful. That said, the most overseen feature by marketing and content is to use it for proofreading and improving the quality of your content.

There are 3 ways to use AI and GPTs

1. To check content structure and logic
2. To check content relevance
3. Ask AI to find flaws in your reasoning

Last note: AI is great. But please don’t forget to keep your content authentically you.

Nothing is as boring and comes across as ‘AI-generated’ as pixel-perfect copy without any fun and play with grammar, words, lines, and brake lines.
