By this point in the history books, you've probably realized ChatGPT, Claude, Perplexity, and all the other AI writing & research tools are amazing. Every time I use them I'm mind blown.

Over the last year and a half, we’ve seen a technical revolution similar to when the Internet came out. OpenAI, the company behind the first major revelation, continues to ship groundbreaking products across the AI world and isn't showing any signs of slowing down.

Their most recent updates, GPT-4 and Claude 3, are some of the most powerful NLP models ever created. They're capable of producing writing with quality even better than human writers/

If this is true, has AI writing reached the point where it’s now completely undetectable and indistinguishable from human writing? Not quite…

The same way AI tools generate writing is actually the exact opposite method of how it’s detected.

AI detection tools like Originality and Content at Scale try to reverse engineer the writing you enter to see how similar it would be to an AI tool like ChatGPT having to rewrite it.

So, what’s the solution?

You have to use words and structure sentences in a way that an AI writing generator wouldn’t use. You can't definitively predict AI text. There's no watermark that gets left behind to prove anything (unlike how plagiarism checkers show you the exact content somebody stole from).

With AI detection, it's just a bunch of words. But for now, AI still writes at a level that can be somewhat predicted, at least if the vocabulary and sentence scrambling aren't too complex.

If you're trying to make your AI writing undetectable, there's a few things you could do to help get around these somewhat faulty detection tools.

How to Make AI Writing Undetectable & Bypass Detection

A few sneaky tools like Undetectable AI make it fairly easy to remove obvious AI-written text from tools like ChatGPT, Claude, Gemini, Perplexity, etc (really any kind of AI writing software).

These undetection tools all combine machine learning algorithms and natural language processing techniques to identify patterns in the text and then get rid of them... aka making it more natural.

While it may be tempting to use AI to breeze through assignments or work tasks, it's important to be mindful of the potential consequences. Please don't do anything unethical or illegal. Only use these tools if it's ethical of you to do so!

Using AI Writing Scrambling Tools

AI has led to tools that hide AI-written text better. They shuffle words, rephrase sentences, and use synonyms. For example, "Exercise improves heart health" becomes "Heart health gets better with regular activity." This keeps the meaning but seems more human. It confuses detection tools by mimicking human writing's variety and style.

The first tool I highly recommend is It helps you change your content to suit various writing styles, such as essays, general writing, marketing material, and more.

To use Undetectable AI, simply paste your text into the tool, and choose the appropriate readability level and tone for your specific writing style.

Once you click the "Humanize" button, the service will work its magic, converting your AI-generated content into text that is not only coherent and engaging but also indistinguishable from human-written material. If you're looking for a more SEO-focused readability approach, you should check out their AI SEO writer.

I took a ChatGPT response about pizza and rephrased it. Check it out:

And look how it did when I threw it in Copyleaks.

Make sure to reread the content. Sometimes, the rephrasing inserts synonyms and styles that don't actually make sense given the context of the writing, but that's just a trade-off you have to deal with when working with a tool like this.

I'm just saying these tools should always be used as an assistant, not a replacement. But for an automatic tool, Undetectable is AMAZING. It starts at $15/month for 15,000 words. You also get a free trial to test things out before deciding if it's worth it or not

I also can't emphasize enough the need to use this service (and the others below) responsibly and ethically. Don't submit anything that could get you in trouble if you're not allowed to.


Next on the list is.... HideMyAI.

While HideMyAI takes a little bit longer to process text & doesn't come with as much complexity, you're still able to get some amazing undetectable content in a matter of seconds.

It works the same but scrambles your text rather differently. Just paste any section of ChatGPT-generated writing into the tool and check it out:

New result reads very well. But how does it do when we put it back into the detector? Pretty damn impressive. Not a single trace. Copyleaks also got a "human-generated" score.

Tweak Sentence Syntax

Once you've thrown the writing in one of those tools, it's time to do some manual labor.

You just have to modify the sentence syntax. This involves adjusting the arrangement of words and phrases in a sentence, as well as the relationships between them.

This will create subtle variations in the structure of your text, making it harder for AI detection tools to identify patterns that are characteristic of machine-generated content, kind of similar to what QuillBot offers.

Doing this manually is similar to what we spoke about earlier but requires a lot more personal fine tuning (a software won't do this as extensively as the human eye).

Try switching between active/passive voice, changing vocab, etc. Just make it seem realistic! It might seem annoying to do, but if you're getting something done with ChatGPT in a matter of seconds, you could spend a few minutes going through your writing to make sure it looks like you actually wrote it.

You should also be utilizing a diverse range of sentence lengths and structures. In natural human writing, it's common to find a mix of short and long sentences, as well as a blend of simple, compound, and complex structures. Just match it with your own writing style.

You can mimic the rhythm and cadence of human writing to a waaaay larger degree in just a few tweaks. Readability is key!!!

Use Higher Level Vocabulary

Another great technique for making AI-generated content less detectable is to incorporate higher-level vocabulary into your writing. This not only elevates the quality of your content but also helps to obscure the telltale signs that it was produced by an AI.

To use higher-level vocabulary, consider replacing common or overused words with more precise or specialized terms. For instance, instead of using the word "important," you could opt for "crucial," "pivotal," or "indispensable."

Likewise, you can employ technical jargon or industry-specific terminology when discussing a particular subject, which lends credibility and depth to your content. Tools like QuillBot are actually perfect for this, they let you paragraph word by word & sentence by sentence until you're happy with your new paragraph.

Keep in mind that while using advanced vocabulary can make your writing more human-like, you need to find a balance between sophistication and readability (I'm assuming you'll have real humans read this somewhere, right?!)

Your content should remain accessible and engaging to your target audience, so avoid using obscure words that might confuse or alienate readers. Always keep in mind user intent, it wouldn't be worth over sophisticating your text if you are writing an article for 5th graders just for the sake of bypassing AI detection.

In addition to higher-level vocabulary, you can also make use of synonyms and paraphrasing to add richness to your content. This approach not only helps to mask the AI-generated nature of your text but also improves its overall flow and cohesion.

By diversifying your word choice and experimenting with different ways to express your ideas, you can create a more dynamic and compelling piece of writing that effectively evades detection by AI analysis tools while still naturally getting your point across.

Final Thoughts & Advice

Ever since these writing tools have become so popular, transforming AI-generated content into text that is indistinguishable from human-written material has been a fascinating and increasingly relevant topic.

Throw your writing into a tool like Undetectable or HideMyAI, do some manual editing, and you'll be good in a matter of minutes.

We've just entered a crazy world, and we're only at the beginning of a road. It'll be an interesting few years, for sure. Leave us a comment on your favorite tool and what works best for you!
