The advancement in AI has made the task of content generation quick and easy. AI writing tools have become very popular, with the projection to gain a market share of $6464.3 million by 2030 at 27% CAGR (2023-2030). These AI writing assistants have made drafting college essays, blog posts, and creative marketing content a piece of cake. But here is a problem: Google focuses more on the content demonstrating E-E-A-T as per the helpful content update. It can identify low-quality, plagiarized, and AI-generated content and impose penalties on it, hence badly impacting the ranking and SEO of a website. The authenticity of content and integrity of a brand is also affected. So, whether you are an online business owner, a blogger, or even an educator, it is necessary to ensure that the content you publish on your website or receive from your student is original, human-written, and plagiarism-free. It is where an AI detector comes to the rescue.
AI writing detectors are designed to identify AI-generated content. They are becoming increasingly popular with the prevalence of AI writing tools. They can tell if the text was generated using an online tool like ChatGPT or written by a human. In this article, we have reviewed the five best AI content detectors for you. Let’s dive into it!
What is AI Detector and How Does It Work?
AI detector, also known as AI writing detector, is software specifically created to detect if some text is AI-generated. It works on advanced ML algorithms and language processing models like those used by Google. They analyze the writing patterns leveraging the huge datasets of human-written and AI-generated text. These language models focus on the following elements in a text to decide if an AI or a human writes it:
It evaluates the randomness and predictability of a text. It measures the probability of the content to confuse the reader. AI-generated content makes sense and is easier to read as compared to human-written. Low perplexity suggests that the content is AI-generated.
It measures the variations in the sentences' length, tone, and structure. AI-generated content reads more smoothly with little variations. The content with high variations is more “bursty” and is more likely to be written by humans.
