Since the launch of ChatGPT, there has been a flurry of AI writing tools which claim to write unique and plagiarism free content on any topic. Although these tools are very useful for generating ideas and they speed up content creation, one must understand that they should be used as a base to create original content rather then simply using their output as a final draft. Hence there is big need for AI content detection tools using which content creators and marketers can understand if there content is human generated because search engines would most likely prefer human generated quality content and any AI tool cannot replace human intelligence.
To help you with this issue, in this article we have listed the best AI content detection tools:
Originality.AI
Originality.AI is one of the most powerful and popular tools for detecting AI generated content. It can accurately detect content generated from Chat GPT, Bard and other AI tools. Apart from detecting AI content with high level of accuracy, Originality.AI can also to assess readability score and check plagiarism. The tool not only helps you as a web publisher to detect AI content, it also helps writers and content marketing agencies to prove that the content they have generated is original.
One good thing that we like about Originality.AI is that they don’t claim to be 100% accurate and present a very real picture of how AI content generation and detection works. For example on their website itself they have mentioned that they have 99% accuracy with GPT-4, and around 83% on ChatGPT.
The only small drawback that we found was that there is no free trial version and you need a credit card to start. However you get to scan 5000 words on installing their free AI detection chrome extension

The monthly subscription starts $14.95 and you get 2000 credits. This one renews each month so you have to utilize your credits every month. For additional credits you need to pay $0.01 per credit. You will get site scans, API, URL scanning and access to future features in this option

It can detect AI content generated through different large language models (LLM) like Brad, Bing Chat, ChatPT, GPT-4 and many more and claims to detect content with 99.6% accuracy.
