Everyone wants access to a free AI detector these days. So, when a new one pops up on our radar, we do our due diligence to tell you if the damn thing works. We usually save you the time and discover the tool is pretty ineffective against undetectable AI, but sometimes results can surprise us.

Today, we’re booting up SurferSEO’s free AI Detector to tell us whether our SEO-optimized article will get flagged by their AI detection tool. It may not be Turnitin, but if it’s online and free, you’ll bet someone somewhere has used it.

What is An AI Detector?

Generative AI tools like ChatGPT use language models that optimize for utility. They want the outputs they generate to inform you about a topic to their best ability. This gives AI-generated text certain identifiable watermarks that an AI content detector’s machine learning is programmed to find. These watermarks include simple and precise word choice, sentence structure, and sentence length measured by perplexity and burstiness.

This article on our blog will give you a deeper understanding of perplexity and burstiness in AI writing.

The industry’s best AI checker is Turnitin and even that system has a 4% false positive rate at the sentence level. Because Turnitin has both expensive pricing plans and unreliable software, some people simply declare AI detectors don't work while others seek out free versions of AI detectors like Surfer SEO’s.

What is Undetectable AI?

Undetectable AI services like StealthGPT rewrites text to make it feel human enough that AI content detectors can’t find the watermarks of AI writing in the text. Using natural language processors, undetectable AI thinks like people do when they write, with randomness, rhythm, and complexity. You can read this article about AI writing vs human writing from Forbes to understand the topic more deeply.

We are going to test SurferSEO’s free AI detector against two different kinds of writing tools. ChatGPT, Stealth AI, and even human writing. I have great faith in StealthGPT because we've mastered how to bypass AI Detectors.

Does The SurferSEO AI Detector Work?

It should be noted that SurferSEO is a writing tool itself, meant for content creation with SEO in mind so content writers can have their articles rank on search engines. We’re only here to rate its AI detector, perhaps one day we can test SurferSEO and StealthGPT’s SEO Writer and see who’s the best AI for content creators.

SurferSEO also offers various integrations from Surfer API to various extensions. It offers an AI humanizer of its own and an AI writing assistant that will help you edit your text with a grammar checker.

Testing Against ChatGPT

So, lets create some AI generated content with ChatGPT. We’ll make an article about surfing. Here’s a snapshot of it:

Now we need to take that article and paste it into SurferSEO's AI detector and see what happens.

I got an immediate 100% score of likely being AI. When I say immediate, I mean less than a second after pasting, which is a little suspect to be honest.

We need to give this software a bigger challenge before we jump to any conclusions though.

Testing Against StealthGPT

Here is our essay after humanizing it with Stealth AI’s unparallaled AI humanizer tool.

As you can see, the article is more readable and human-like after the Stealth AI treatment. It should be able to bypass AI detectors with ease now. Here’s how it fared against Turnitin:

Our text received a perfect score of 0% AI generated against Turnitin. It’s established that StealthGPT uses more advanced AI than Turnitin AI detection though, this article is about testing our undetectable text against the free version of an AI detector that isn’t even the primary feature of a small content creation app.

So, this is what happened when StealthGPT went up against SurferSEO:

We bypassed their AI detection technology with a score of 34% likely AI, meaning SurferSEO determined the text was likely human and original content.

34% is not a score we pride ourselves in. It’s a score SurferSEO should pride itself in though, if you scour our numerous blogs testing various AI detection tools, this service does better than most tools.

Testing Against Human Writing

Because I’m wary of the speed in which SurferSEO gave me a result, I’m going to feed it an article I wrote from our blog about how to use AI to run a blog and see if it will flag it as AI writing.

With a score of 0% AI-likelihood I will give this AI detector its flowers, it shows pretty good functionality.

How Reliable is Surfer SEO’s AI Detector?

I would call it reliable. StealthGPT might’ve bypassed their AI detector but by a relatively bad score, and we bypassed everyone. It was completely correct about other pieces of content we passed through its service and it analyzed the text at a much faster rate than any other service you could find online from Turnitin to Originality.AI and more.

Consider SurferSEO a reliable tool. And we only tried the free version of its AI detector, I would assume it's capablity making SEO content, editing, proofreading, researching, and grammar checking are also functional.

Conclusion

SurferSEO’s free AI Detector does work. StealthGPT still bypassed it but we got a better score from a much more powerful and popular AI detector than Surfer SEO’s. If I wanted to give the AI Detector a grade, I would say it’s a B, which stands for beatable by StealthGPT.

With proven functionality against the industry's best, StealthGPT should always be your weapon of choice whether it's to bypass AI detectors or SEO writing that gets your content to rank on search engines.

Whether you want to go pro or keep it basic, StealthGPT is the key to unlocking your potential as a creator.

FAQ

Is Using AI Writing Plagiarism?

Using text generated by artificial intelligence like OpenAI’s ChatGPT is not considered traditional plagiarism. Academic institutions consider it “AI plagiarism” because generative AI engines only create original content instead of stealing someone else’s words or ideas without proper credit. Read our article about AI ethics in Academia for more.

Who uses Undetectable AI?

Everyone from students to professionals. Anyone who uses text can find a use for undetectable AI services to write articles, essays, email, social media posts, and more. Undetectable AI writing just means human writing and if we want to use AI text, we certainly would prefer to use human writing than text that feels machine-like.

Can I get a Chrome Extension or Gmail integration of an AI Detector?

Yes, many AI detectors and AI writing tools offer extensions to google apps from Chrome to Gmail.
