Best AI Content Detectors: These apps flag plagiarism and rephrased content

We all strive to produce content that’s compelling and well-written. And now that we’re using AI content tools that have made the content creation process easier, what about the ethics of content that’s no longer created by humans?

AI apps have made it easier for plagiarism to flourish

Can AI content detectors stay ahead of the new detection apps that are hitting the market? This is an ethics problem that really hasn’t been adequately addressed, and the issue is surfacing as schools, businesses and government agencies set standards for original content. They’re looking for content that’s generated by humans–not by machines.

AI content tools and the ethics

AI content tools are software programs that use artificial intelligence to assist with various aspects of content creation. After we enter our topic and keywords, AI content writers generate an article based on this information. We are to assume that the article is plagiarism free.

AI articles aren’t ready for primetime

These AI articles are drafts and need a lot of work before they’re ready for primetime. There’s duplication. They lack the examples and data that make them relevant. There are no case studies or examples of personal experience that make writing compelling.

For my AI content, I delete some of the garbage and go back and start updating the drafts. I google, looking for interesting data and case studies. I’m a good writer, so it’s easy for me to rewrite this, but it’s entirely possible that snippets of information don’t get rewritten. And those snippets well may get flagged as plagiarism.

Plagiarism means that it only needs to resemble the original

It’s important to know that search engines identify plagiarism as information that resembles the original—it doesn’t have to be identical to the original phrasing to still be regarded as plagiarism. You can’t change a few words and think that it’s now plagiarism-free.

A plagiarism lesson from Writesonic

I use Writesonic, and I love this app that I’ve been using for a year or so. So when I get ready to draft an article, I have a choice of 4.0 or the newer 5.0. For this newer version, I just key in my topic, then a few urls of relevant articles. Well, guess what? The resulting article gets flagged for plagiarism. So I’m sticking with 4.0 where I identify topic and four longtail keywords. 

These AI tools are making our lives easier on many levels, but inevitable problems are emerging. Plagiarism is an obvious one because the ethics of AI tools hasn’t even begun to be addressed.
