15 Best AI content detectors + ChatGPT detector software

Image Best AI Content Detector - AI Content + Plagiarism Direction

There is a growing number of AI content generators capable of producing wide-scale SEO-based content for almost any industry. AI’s ability to create any type of content with a human-like tone, style, and structure has given rise to questions about originality, content quality, and the implications of AI-generated content for the future.

AI content detectors are one answer to this rising dilemma. The rise of content-generating tools has inevitably led to the simultaneous growth in the number of AI detection tools. Below we give a tour of the most popular and best AI content detectors.

AI Content Detector Software – Overview

AI content detectors are tools to detect whether a text is completely or partially generated by AI. Most of these AI tools are trained on Chat GPT models and Natural Language Processing (NLP) to recognize GPT texts as well as texts generated by other AI tools.

The widespread access to AI content generators has created some serious dilemmas in particular for educators, web publishers, and recruiters from content writing agencies.

Originally, teachers or publishers used plagiarism detectors like Turnitin and Copyscape, which compare the input to millions of online content pieces and flag parts that might have been copied. However, as AI text generators create texts from scratch, they could bypass plagiarism detection, calling on new technology to keep content in check.

AI content detectors are designed to solve this problem. Whether you are an educator, a recruiter for a content writing agency, or a blogger, you can submit your input to a content detection tool and check whether the text originates from a human mind or an algorithm.

Additionally, writers and bloggers need AI detection tools because AI-based content can be uninspired, banal in tone, and even factually outdated. While there is no clear evidence that Google penalizes AI-based content, bloggers and businesses understand that generic content can hurt their brands in more ways than one.

Google is quick to replace content that fails to capture the attention of its online visitors and, amid the sheer degree of competition, AI content detectors can help you ensure that you are putting out purposeful and tailored content for your audience.

Writer is a popular and diverse AI text generator that specializes in producing content that is tailored to multiple industries, including finance, healthcare, life sciences, e-commerce, retail, technology, etc. The technology also comes with an AI content detector that is only available as an API in the Writer app.

Currently, Writer AI is limited to checking only 1,500 characters at a time.

Once Writer’s AI content detector scans your text, it will assign it a percentage that will serve as the score for content generated by AI. You don’t have to create an account to use this tool, albeit enterprise plan subscribers can enjoy higher limits and full access to the API, making it suitable for recruitment companies that hire content writing agencies.

Like most AI detection tools on this list, all you need to do is paste the text into the AI locator and it will highlight AI-based texts or sentences. Its simple interface makes it an easy tool for teachers and other professionals when assessing texts. However, teachers can’t upload bulk content and will have to upload each student’s input individually.

Corrector’s AI content detector is a search engine-approved software, making it a commensurate solution for web publishing. Users should note that they can only input text of no more than 800 words, meaning that they might need to paste the text in sections.

Platform: Corrector AI | Style: AI Detector

13. SEO AI Detector

Image AI Content Detectors - SEO AI Detector 

SEO.AI has created an AI detector for Chat GPT that scans input against four different AI detection models. SEO.AI is primarily an SEO-based content-generating software that is currently offering a free app for detecting content produced by AI.

You can upload or paste text that is up to 5K characters long and check how original and high-quality your input is with the technology’s AI detection tool. The latter uses algorithms on prediction, entropy, perplexity, and correlation to determine the nature of the input.

Other than detecting AI-based content, users can also visit the website to access a series of insightful articles on Google’s latest policies on machine-generated articles and how these affect SERP rankings.

Since SEO.AI is primarily a content generation solution as opposed to a content detection tool, it doesn’t offer a great array of features or luxuries like uploading long-form content, content in bulk, or accurately analyzing content in any language other than English.

Nevertheless, it is a handy solution for web publishers and teachers who do not have the option to invest generously in AI-detection software.

Platform: SEO.AI | Style: AI Content Detector
Price: Free (up to 5,000 words)

14. GPTRadar

Moreover, it can ensure compliance with Google’s SERP guidelines and help you fix the tone of your text to streamline and optimize your brand’s reputation. 

At $0.02 per token (125 words), it is a reasonably priced AI detection software, albeit some free tools can give you similar results. 

Platform: GPTRadar | Style: AI Content Detector
Price: $0.02 per credit (1 credit = 125 words). View.

15. OpenAI Text Classifier

OpenAI’s Text classifier is a finely-trained GPT model that is capable of detecting the extent to which content is generated by various AI tools, including Chat GPT. According to OpenAI, the text classifier is “available as a free tool to spark discussions on AI literacy”. As it is not commercially aimed at any sector, the tool comes with certain limitations.

Given that the primary aim of the tool is to foster conversations around the differences between human-generated and AI-generated content, OpenAI warns users against qualifying its results as the final verdict on the degree of text originality. Instead, OpenAI encourages users to scan the responses and provide feedback on the tool’s performance.

One limitation is that users can’t post content below 1,000 characters (150-250 words). Once you paste the content, the classifier will assess the text and label it as either very unlikely to be AI-generated, unlikely to be AI-generated, unclear if it is AI-generated, possibly AI-generated, or likely to be AI-generated.

Keep in mind that OpenAI admits to having trained its text classifier on a limited number of models and, therefore, can’t provide an accurate estimate. In addition to requiring a Chat GTP login, there’s also a chance that the classifier will get things wrong on texts written by children or texts available in languages other than English.

How to Choose the Best AI Content Detector

Image Tips for Choosing the Best AI Content Detector

AI content can look convincingly similar to human-generated content. This is why you must choose AI software with a high degree of detection accuracy. Currently, many AI detection tools admit to the possibility of false positives and undetected AI content in their results. 

OpenAI Detector, for example, has a clear disclaimer on its site that the technology simply does not have enough human-generated sources to compare and accurately determine whether the content comes from AI or not. For this reason, you must look for the following metrics when choosing the best AI detection tools.

1. Accuracy: As a user, it is your job to research how accurate the results of your chosen AI content detector are. Winston.AI and Sapling have been rated as two of the most accurate AI detectors but there are other competent tools that you can also look into.

2. Additional features: While an AI detector’s basic task is to detect machine-generated content, some tools offer additional features for the same price. GPTZero, for example, allows teachers to upload multiple files at once, which can speed up the process of checking for AI input.

Similarly, there are tools that not only highlight sections of content that are AI-generated but also offer to help you bypass detection.

The kind of features most suited to you will boil down to whether you are using the tool as a teacher, a web publisher, a content agency recruiter, etc. One example is Originality AI which offers features such as shareable links to its reports and SEO optimization which are highly tailored to the needs of content writing agencies.

Therefore, make sure to thoroughly assess all the features that your chosen software offers as part of its suite.

3. Pricing: The pricing for an AI content detector varies vastly from relatively expensive to completely free. While the difference in price points comes with a catch, it is also important that you do not strain your finances. For anyone who wants to test the waters or requires the most basic of solutions, there are some decent free AI detection tools to start with.
