AI Content Detector Tools

Top 10 AI Content Detector Tools For Individuals and Businesses

Share your love

Artificial intelligence is part of our lives now. We use AI tools daily to complete tasks that previously took days. AI tools are a force to reckon with in the modern digital business space, from creating new content to generating visuals for websites and marketing campaigns.

What is AI Content?

Simply put, AI content is text generated by AI tools or software based on the user prompt. Meaning that the tool relies on the prompt to create the content.

Usually, the language learning model scours the internet for information related to the main topic described in the prompt, summarizes it, and presents it as an article, report, or essay. The more detailed and comprehensive the prompt, the better the content output.

Though effective in helping professionals like you and me finish content creation projects faster, the quality of the content is a major concern. One of the main downsides of AI-generated content is that it lacks a human touch. It’s nearly impossible to connect with customers.

Like other modern tools, it is important to use them sparingly and compare the features to know if they suit your business and content creation needs.

What is An AI Content Detector?

To connect deeply with your target audience and generate leads and sales, you must stop taking shortcuts and invest in quality human-written content.

An artificial intelligence detector is a software that is designed to detect whether content is human-written or AI generated. One of the cues of AI content is that it lacks a human touch and creativity.

The sentences and choice of words follow a pattern and trend. Other factors that AI content detector uses to analyze and tell whether the content is human-written include repetition of words and phrases, the inclusion of inaccurate or outdated data, and sentence length

Here is an unbiased review of the top 10 AI content detector tools you can use to know whether your website content is human-written or AI generated content.

Tips to Avoid AI Detection

In 2024 and beyond, we expect to see significant improvements on how AI content detectors work. It will be difficult to beat these tools, but not impossible. Here are five proven tips on how to avoid AI detection.

Use Conversational Prompts

AI content detectors use reverse engineering to determine if the content is machine-generated. They use the content generated to analyze sentences and words for patterns and unnaturally punctuation.

You can avoid AI detection by using conversational prompts instead of generic prompts. For example, you can prompt the tool to write the content using a friendly tone, as if it’s giving advice to a friend or colleague. Indicate it should use a conversational writing style and include personalized examples.

The goal is to add a human touch to the content by altering the conventional ways that the AI content tools structure the sentences.

Use AI Writing Tools With AI Detection Capabilities

Unlike before, there are modern tools that you can use to run AI checks on content generated before publishing.

One such tool that is used globally by content creators is Agility Writer. But there are many other options. Compare and contrast the features to find one that best suits your needs. It’s also recommended to check the content generated with other AI content detectors to be sure it’s undetectable.

Use Rewriter Tools

Rewriting content generated by ChatGPT and other similar tools is another way of avoiding detection. Tools like undetectable.ai are effective in turning AI-generated content into human-written content in seconds.  

If you decide to use them, proofread the rewritten copy before publishing to be sure the data is accurate and free of grammar errors.

Write Sections Separately

One of the common mistakes that results in AI detection is using AI tools to write the whole article in one instance. Doing so results in the tool using an easy-to-detect pattern of sentences, words, and flow of ideas.

Get undetectable AI content by prompting the tool to create content in sections. Each section should be created separately and using its own prompt. Add nuances and sentence variations to make it more difficult for AI content detector tools to flag it.

Personalize the Content

As mentioned earlier, one of the main challenges of AI content is that it lacks a human touch, making it difficult for the readers to understand and respond to the content. Personalize your AI content by adding personal experiences and anecdotes.

According to the recent Google content guidelines, E-E-A-T (Experience, Expertise, Authority, and Trustworthiness), content that has examples ranks better than generic content that offers little value to the readers.

By applying this hack, you will kill two birds with one stone, avoid AI detection, and improve your content ranking on Google.
