More people may be struggling to deal with the growing amount of AI content out there these days. Some surveys suggest that up to 58% of marketing professionals believe that the majority of online content might be made with AI within the next couple of years. Educators may also be struggling to deal with the growing number of students using AI. These aren’t empty worries, since, according to some reports, many students admit that they have used AI to do their schoolwork. 

AI detectors are the first line of defense against the growing volume of content being made with AI. There are a lot of AI detectors out there, but some may not be effective enough. 

If you are looking for an AI detector, then you need to know which ones are worth the investment. Some of the best, according to reviewers for this article, are listed below. 

AIDetector. com

AIDetector. com is one of the new tools for artificial intelligence, and is considered a strong option by some users. According to their website, it allows you to scan up to 1,000 words at a time for free. You can test both images and text to see if it is created in any of the major generative AI languages. AIDetector. com also allows you to test to see if content may have been plagiarized or not. 

This is overall one of the better tools that you can use if you are interested in avoiding content that has been made with AI or plagiarized. Therefore, according to some users, it is one of the more popular tools in both corporate and academic settings. 

The service is reasonably affordable. You can either purchase credits with the pay-as-you-go option or subscribe for a monthly fee. It may not be the cheapest on the market, but it may be a good deal considering the quality of the service. 

ZeroGPT

ZeroGPT is another AI detector worth looking into. This tool also has a plagiarism detection option for people who want to prevent that, as well as avoid AI content. It also allows you to see if content has been paraphrased to avoid AI detection, which is a feature that, according to some users, some other popular AI detectors lack. 

According to their website, this service may also be compatible with some popular apps. This may be helpful for anybody who wants to identify AI-generated spam across various platforms. 

GPTZero

GPTZero shouldn’t be confused with ZeroGPT, since they are two different tools. However, GPTZero is also a well-known AI detector. 

According to their site, this service is available for $10 a month. Some reviewers note that GPTZero offers useful features at a low cost. 

However, the affordability may come at the expense of additional features. The tool doesn’t seem to offer plagiarism detection capabilities, unlike some of the other tools on this list. It may also be more limited in identifying AI content in different languages (human languages, not LLM ones). 

Copyleaks

Copyleaks has a reputation for being one of the most popular AI detectors on the market. It is certainly good, but may not deliver the most complete results. However, it is still better than some of the lower-tier AI detectors, so it deserves to be included. 

According to their site, Copyleaks offers its AI detection service for $7.99 a month, which makes it one of the more affordable options available. However, you may have to pay more if you also want the plagiarism detection tool. It claims to offer support for 30 languages. 

Quillbot

Quillbot may appeal to budget-conscious users looking for both detection types. According to their site, it offers both AI and plagiarism detection services for just $8.33 a month. It offers support to see if content was made with AI in English, French, Spanish, German, Dutch, and Portugese. Some users say that it has a decent track record for identifying both AI and plagiarized content, so it may be worth looking into if you need an economical option.
