AI writing detection is an intricate process that aims to identify certain patterns or characteristics specific to AI-generated content, resulting in a corresponding score.

So, how can one avoid the risk of being detected while writing with AI (which is not inherently wrong) or, worse, being falsely accused of employing AI when in fact they have not?

For now, one approach is to utilize specific tools to scramble the words and sentence structures, thus perplexing these detection systems. However, it is likely that in the near future, discussions around this topic will become obsolete as people realize the unpredictable nature of AI. But that conversation is a topic for another time. For now, here are the most impressive tools we have encountered.

The Best AI Content Writing Tools of 2024

Before delving into these tools, it is indeed necessary to test their effectiveness. To evaluate their performance, I have requested ChatGPT to generate a paragraph on divorce attorneys. Let's examine the output and assess how it fares when subjected to an AI detection tool:

Isn't it a well-crafted text? Shall we put it through Originality.ai and see?

Alright, it's evident that this is not an ideal situation. Let's now discover the top-notch tools that excel in aiding the avoidance of such circumstances.

Undetectable AI

One of the most remarkable tools I have ever utilized is Undetectable AI. It operates by skillfully rephrasing numerous sentences within a paragraph while retaining the original meaning.

Upon submitting the generated paragraph to Undetectable AI, it takes approximately 40 seconds to produce a completely transformed paragraph. Furthermore, when subjected to Originality analysis, the resulting text exhibits an exceedingly low AI-writing rate, nearing 0%.

And just like that, you now possess AI-generated content that can evade detection by most major checkers. (In my opinion, Originality is the most robust, so I chose to test with that.) Currently, Undetectable AI stands out as the sole platform capable of bypassing Originality and remaining undetectable.

Undetectable also offers the flexibility to adjust the tone and style of the desired output. Whether you need to rephrase content to match a high school paper or emulate the language of a PhD student for a professional report, Undetectable AI can accommodate those requirements.

The tool allows you to modify up to 250 words of writing for free. Additionally, there are subscription plans available starting at $9.99 per month, providing access to rewriting up to 10,000 words of content. I highly recommend trying out the free word sample to determine if it meets your needs!

QuillBot

During my search for content rewriting tools, QuillBot was actually the first tool I came across. It performs effectively, although it does require more user editing compared to the other tools we previously mentioned. If you desire complete flexibility to rearrange and rephrase your text, essentially visually moving words around, QuillBot is likely the optimal choice for you.

Once you input a block of text into QuillBot, you will notice that certain words are highlighted in orange and blue. By clicking on these words, you have the option to replace them with alternative synonyms.

QuillBot allows you to customize the complexity of the suggested synonyms, tailoring them to your specific needs. Additionally, you can adjust the tone of voice, whether you prefer a more formal, creative, or other style of writing. Moreover, QuillBot supports multiple languages, making it suitable for sentence editing in languages other than English.

WordAI

Another tool that operates similarly to Undetectable AI is WordAI. It functions in the same manner: you paste your text and with a click of a button, you can view the rewritten version of your text

WordAI offers a wide range of features, including the ability to rewrite content in multiple languages. It also provides API access for developers. However, it's worth noting that WordAI's pricing starts at $57 per month, which may be considered relatively high compared to other tools. Nevertheless, if you are seeking a more comprehensive solution that extends beyond AI rewriting and encompasses content generation as well, WordAI offers robust capabilities.

Content at Scale

In addition to the aforementioned tools, it's worth mentioning Content at Scale. While not specifically designed as a standalone AI text rewriter, the full-length articles it generates generally remain undetectable by AI detectors.

Content at Scale is particularly valuable if your goal is to generate lengthy articles that are difficult to identify as AI-generated. It serves as an excellent tool for creating undetectable AI articles.

Although it may have a few minor issues that need to be addressed, such as occasional messy generations or incorrect data retrieval, I recommend exploring Content at Scale. If you're interested in learning more about creating full-length articles that are completely undetectable, we have a comprehensive review available. It's even possible to transform an entire YouTube video into an undetectable blog post using this tool. It's truly impressive!

Final Thoughts

It is essential to bear in mind that these tools primarily function by rearranging sentences, which can occasionally result in peculiar or awkward structures. Therefore, it is important to carefully review the generated paragraph for any inconsistencies or unusual sentence constructions.

When utilizing these tools to rewrite AI content for the purpose of avoiding detection, it is crucial to recognize that their objective is to make the text appear more human-like. Human writing exhibits a higher degree of variability and creativity within its sentences, which can potentially be used to identify AI-generated content if tools like ChatGPT produce repetitive patterns.

Responsible and ethical usage of these tools is paramount, and it is crucial to understand the underlying reasons for rewriting AI-generated content. ChatGPT is indeed an extraordinary tool, and its continuous development promises increased creativity and power.
