Best AI Content Detectors - DemandSage

As AI writing tools become more mainstream, there’s a pressing need to have an equally robust AI content detection tool to keep your content original.

A new digital revolution is in full swing, curating content using AI writing tools. There’s Jasper Al, Rytr, Content Bot, and more – each offering extraordinary AI capabilities to weave content, but there’s a catch – Google can detect AI-generated content and doesn’t like it. Therefore, if the content is completely generated by AI, in all possibilities, Google will flag it, severely impacting the website’s SEO and ranking.

You don’t want it to happen with your blog or website. Correct? What you need is an AI Content detector tool. Read the article to discover the top AI Content detection tools available now. You will find out the best tools and how useful they are in practice.

How Accurate Are AI Content Detectors?

Before diving in to explore the best AI content detectors, it’s prudent to analyze their accuracy first. The bad news is no AI text detector tool is 100% accurate. I tested multiple tools and found their accuracy swirls between 65% and 90%. AI writing tools’ amazing natural language processing capabilities are the primary reason for this. In comparison, AI text detectors still need to catch up to these extremely efficient AI writing tools.

Wrapping Up: Top AI Content Detectors (2023)

To conclude, AI content detectors are becoming increasingly essential in the wake of AI writing tools. More so when Google clearly seems to be at an impasse with AI-generated content. It’s true that AI writing tools massively simplify the writing process; however, the human touch, emotion, ingenuity, and creativity should always be there to ensure Google doesn’t flag it as low-quality content. Interestingly, most AI text detectors are available for free ( although with varying accuracy). It’s worth a shot to weigh your content with them and ensure it doesn’t give vibes of AI-written content. 


Should I use an AI content detector?

Google, on many occasions, has clearly stated that it considers AI-generated content low-quality. Therefore, pure AI content is against Google’s webmaster guidelines. Recently, John Mueller, Google’s Search Advocate, again asserted that AI-generated content is spam. Therefore it’s prudent to check your content for originality before publishing it on your website. 

What AI content detector tool should I use?

It depends on your requirements. There are both paid and free AI text detectors available. However, if you are all in for accuracy, I think there’s no better tool than originality.ai. In case you are looking for a free tool, content at scale and sapling.ai is worth considering. While the former is more geared toward accuracy, the latter is committed to AI text detection for all NLP-based models.

Can Google detect AI content?

In all likelihood, Google can detect AI content. Its webmaster guidelines explicitly iterate that AI content is low quality and spam. Therefore it’s safe to assume it must have placed mechanisms to detect AI content. 

How AI Content Detectors Work?

AI content Detectors rely on the same NLP models that the AI writing tools utilize to generate text. In short, they are trained to detect the inherent patterns and use of words and phrases in AI content. These tools then rate the content based on the likelihood of how Google will see it.
