How Does Google Detect AI Content Video
Best AI Checker + Blog Post GeneratorLearn More
The new feature added to our favorite AI writer, Content at Scale's AI Detector, is topping our list.
We love this detector because it has the ability to detect when content comes from ChatGPT, GPT4, Bard, Claude, or any other AI model within moments.
You can generate your content using Content at Scale’s AI writing service and check for its human-like quality using the built-in detector before posting.
It not only gives you a simple score out of 100 on how human the content is and how likely it is to be detected by Google as artificial, but it also breaks that score down into key elements like predictability, probability, and pattern, giving users more insight into what about their content seems “AI.”
Another new feature that Content at Scale recently added that we’re excited about is the sentence-by-sentence breakdown. The detector will highlight each sentence of content in a color that corresponds to its detectability, so you can fix the sentences that appear to be AI-written and not worry about sentences that work.
An added bonus: most of the Content at Scale content ran through it earns a high “Human Content Score,” so you have to do less work on editing it.
Content at Scale AI Detector Pro
Content at Scale has added a Pro version of their AI Detector. For $49 monthly, you’re now able to get scans of up to 50,000 characters in one scan—that’s between 7,000 and 12,000 words—and a rewriting tool. We love this upgrade.
Content at Scale already produces undetectable content, so having an AI rewriter/paraphraser onboard that produces quality content saves me from having to go elsewhere for my rewrites and still having to do major edits because that output isn’t great.
The new addition to Content at Scale’s suite of tools makes it more of a timesaver and a one-stop shop for content creators.

Undetectable.ai is an all-in-one AI writer, paraphrase, and, you guessed it, detector.
What sets this AI writer’s detector apart is that it aggregates scores from 8 other AI detectors. This means you can see AI detection likelihood scores from GPTZero, OpenAI, Writer, Crossplag, Copyleaks, Sapling, Content at Scale, and ZeroGPT, all in one place. Because of this, the detector is pretty good at detecting AI content.
The only drawback to this detector is that it won’t highlight specific parts of text that seem less human, so you can hone in on what to edit. But when you consider that the same software also paraphrases and writes original content, Undetectable AI is worth a try.

Checking for both AI and plagiarism, Originality.AI puts the user in control of their content’s originality.
Since AI writers largely pull their information directly from other posts on the internet, the risk of plagiarism can be pretty high. With Originality.AI, not only can site owners gain insight into how human-like their content is, but they can also see how original the content itself is.
By doing both at the same time, site owners and content creators can save time and money and mitigate the risk of Google detecting any machine-created content.

The “home of machine learning,” HuggingFace is used by over 5,000 organizations, including Grammarly and Google AI.
Though it’s an open-source AI community where folks can share ideas, the site also has a free AI detection tool.
All a user needs to do is copy/paste their content into the box, and it will show the user where it ranks on a “fake” to “real” scale.
Results get more accurate the more content the tool is fed, so this one may be better for folks who are testing longer AI-written content.
They also have a good AI image detector.Learn More
Giant Language Model Test Room (GLTR for short) is a detection tool that uses “a suite of baseline statistical methods that can detect generation artifacts across common sampling schemes.”
This was created by a team from MIT-IBM Watson AI lab and HarvardNLP using the GPT-2 language model to differentiate between real and AI-created content.
GLTR essentially color-codes each word in a post to detect how likely that word is to appear in that position in a sentence.
For instance, a word that ranks within the most likely words is highlighted in green (top 10), yellow (top 100), red (top 1,000), and the rest of the words in purple.Learn More

With a straightforward name, Writer is a leader in… well, written content creation.
It also has an easy-to-use AI content detector to make it easy for users to check their AI-generated content before sending it out into the world.
Similarly to Content at Scale’s AI detector, Writer’s shows a detection score in percentage.
If you need help, they have a dedicated customer support team as well.
Free AI Detection Tools
To fly under Google’s radar, many companies have launched free AI detection tools.
These tools are designed to search through written content, looking for phrases that are organized in a strange or overly predictable way.
These tools then calculate how “human” the content seems, giving it a score that reflects how natural and human-made the content is.
A few free AI detection tools include:
Here are the best free tools to check content generated from ChatGPT.
AI Detector Tool Accuracy
How Accurate Are AI Content Detectors?
Since all of this is so new and Google hasn’t communicated exactly how they detect AI-written content, there is no way for an AI detector to be 100% accurate.
They will give you a score (typically out of 100) of how “human” the content seems and indicate whether or not it is likely to be detected as AI-written content.
This number is a great jumping-off point to get an idea of how much editing needs to be done, but getting a human set of eyes on it is always a good idea to make necessary adjustments for the best content possible.
What Is the Most Accurate AI Checker?
Winston.AI stands out as the most accurate of AI detectors, specifically designed to discern between content written by humans and those generated by AI. It is renowned for its precision, claiming a remarkable 99% accuracy in detecting content produced by models like ChatGPT, GPT-4, and Bard, according to its internal testing results.
This tool is meticulously crafted to fulfill its core purpose: to distinguish human-written text from AI-written counterparts effectively. It's not just about identifying AI-generated content but about the reliability and assurance it provides in doing so, making it the preferred choice for those who seek uncompromised accuracy and reliability.
AI Content Detection Tools – Accuracy Score Comparison Table
We generated text through AI for our prompts and ran the same text for each detector tool.
Here are the results:
AI Detector Tool
|Content at Scale||32% (AI) - 68% (Human)|
|Originality.AI||99% (AI) - 1% (Human)|
|Winston||100% (AI) - 0% (Human)|
|Hugging Face||98.54% (AI) - 1.47% (Human)|
|GLTR||Probability given - no score|
|Kazan SEO||98.53% (AI) - 1.47% (Human)|
|Writer||0% (AI) - 100% (Human)|
As you can see in the table above, there’s a wide range of scores for the same generated content. The one that stood out was Writer had a 0% AI score, which I didn’t expect. Originality and Winston seems to be the hardest one to pass, while Content at Scale seems to be a bit more lenient and offers a bit more insight on how to optimize.
However, scores may vary even more depending on the prompt, so our recommendation is to pick one tool and stick with it. And, of course, it’s always best to have a human editor and proofreader review the content, regardless of the human score output.
How Reliable Are AI Content Detectors?
AI detectors are becoming more reliable, but they are still far from perfect.
You can put the same paragraph into every AI detector on this list and get wildly different results from each, showing that the technology hasn’t advanced enough to be 100% reliable.
With Google and AI writers like ChatGPT constantly switching things up, it’s nearly impossible for current AI detectors to catch everything.
For this reason, we suggest always, ALWAYS, getting a human editor to look over any content before publication. Human eyes can catch things like machines can’t, plus they’re essential for making AI-written content sound human.
How to Fact-Check AI-Generated Content
An important step in preparing AI-written content for posting is fact-checking.
AI writers just pull information from sources all over the internet without discernment, meaning it’s easy for false information to end up in your AI-written content.
Allowing an editor to give AI-written content a look is important.
Fact-checking can be as easy as looking up any statistics and claims made within the content and cross-checking them with credible information sources.
How Do AI Detection Tools Work?
AI detection tools work by using a language model similar to the ones used by Google to predict likelihood of certain words and phrases in content. Using this judgement, it is able to give users a score on how “human-like” the content will appear in Google’s eyes.
These tools can help site owners who publish content use AI writers to produce a higher volume of content without risking penalization from Google.
Are AI Detection Tools Worth It?
Since so many AI detection tools are available for free, they are absolutely worth it to ensure that any AI content created will pass under Google’s radar and have the opportunity to rank high in search.
Google and AI-Generated Content
The reason for all of these detection tools is Google’s relationship with AI.
Technically, AI-generated content has always gone against Google’s Webmaster guidelines. With all of the new technology, folks have been wondering if Google has maintained its stance on the new way to create content.
In a recent SEO office hours, Google’s Search Advocate John Mueller reiterated that AI writing tools are considered AI-generated content and considered spam, which makes them a no-go when it comes to following Google’s rules.
They haven’t really specified how they can tell whether content is AI or not, but it’s better to err on the side of caution and use a detector before hitting “publish.”
