If you have no time to read the whole article, here are my top 3 picks for the best AI content detectors.
With the rise of artificial intelligence and its use in content creation, it’s no surprise that AI writing tools are becoming an increasingly hot topic.
Unfortunately, AI-generated content lacks creativity, personality, and context most of the time.
This begs the question, “Can Google detect AI content?”.
If so, you’ll want to future-proof yourself and use the best AI content detectors to make your content authentic in the eyes of Google.
Publishing unedited AI-generated content for the purpose of ranking is a no-go under Google’s webmaster guidelines.
You might have gotten away with it in the past but not for much longer.
In this article, I’ll cover the best AI content detectors to protect your articles by avoiding spam detection, increasing rankings, and improving user experience.
What Are the Best AI Content Detectors?
Here are my top 11 picks for the best AI content detectors.
1) Originality AI
Best for Web Publishers
Originality.AI is an AI-detection and plagiarism checker tool targeted toward serious content publishers.
According to tests run by them, they are one of the most accurate AI detectors for GPT3 content, with only slightly reduced results for GPT3.5 and ChatGPT.
Update: They announced on February 24th, 2023, via email that they have an unreleased AI Model, which was even more accurate.
Results were 99.07% accurate on 35k GPT-3 samples and 4.86% false positives on 35k known human blog posts.
They also have very generous team features and API integrations.
Key Features
Pros and Cons of Originality.AI
Pros
Cons
Pricing
Originality.AI currently only has one pricing model.
It costs $0.01 per credit, where one credit scans 100 words.
That means a 2500-word article will only cost you $0.25.
2) Winston AI
Best Originality AI Alternative
You probably haven’t heard about these guys yet, but I can tell you “best originality AI alternative” doesn’t mean Winston AI is inferior.
It has the potential to overtake them.
For a relatively new tool, it’s packed with a ton of unique features that most of the detectors on this list lack.
Originality AI currently wins in accuracy but falls short in other areas compared to Winston AI.
I spoke to the founder via email and got some interesting nuggets.

Best for Detecting GPT-2 Content Scientifically
GLTR (Giant Language Model Test Room) is an AI detection tool created through a collaboration between MIT-IBM Watson AI Lab and Harvard NLP.
It was trained on the GPT-2, 117M language model from OpenAI to analyze text and determine how likely a human-created content was.
The tool assigns probabilities to each word by comparing text inputs to what GPT-2 would have produced instead and highlights them using different colors.
If there is a lot of text in Green and Yellow, it’s likely AI-generated.
But if there is also a lot of Red and Purple text, it’s more like it is human-written.

What Are AI Content Detectors?
AI Content Detectors are software tools that use artificial intelligence to determine if a piece of text content is written by a human or a robot.
How Do AI Content Detectors Work?
AI content detectors work by recognizing specific patterns or characteristics of the input text content by comparing it with the data it was trained on.
It recognizes similarities in the input text’s structure, phrasing, and frequency and then assigns a probability score.
So, when it finds something that matches what it has learned, it will flag it as a positive match and classify the words or entire paragraph accordingly.
This process falls under NLP (Natural Language Processing) with machine learning or deep learning using neural networks to produce an artificially intelligent model that can take an input and give an output as a prediction.
Without going into too much detail, an AI model is trained like this:
Are AI Detection Tools Worth It?
You don’t want to create content blindly with AI marketing tools only to be penalized by Google in the future.
AI detection tools are definitely worth using to ensure that the content written by an AI tool or even freelance writers (because some of them use AI writers even when they tell you they don’t) don’t get flagged.
Besides, most of the tools on this list are free, so there is no excuse not to use them.
Why Is It Important To Detect AI Content?
By detecting AI content, we can ensure that the information we view and interact with is authentic and accurate.
Here are other practical applications:
What are the Limitations of AI Detector Tools?
The limitations of AI Detector Tools will always be the data it’s fed and trained on.
Because if the training data is not a good representation of the type of content, the tool will be analyzing, then the results are likely to be inaccurate.
AI Model Limitation Analogy
Imagine if you knew nothing, and I started by showing you pictures of different Chickens.
The word next to each image also says “Chicken.”
So now you have learned what a Chicken looks like without knowing any other kind of bird existed.
Now, if the following image I showed you were a duck, knowing only what a chicken is, you would think it’s similar and say it’s also a chicken.
Here are more limitations:

Love the energy on the blog, truly a great read.
Which one would you think is the best (performance, UI, feel etc) in your opinion?
Hey Tracey!
I feel that overall Content at Scale is the best. In terms of accuracy, Originality.AI still had more accurate predictions but [email protected] still had some false positives/negatives.
[email protected] just recently had an update to their AI content detector and provided users with more metrics.
It now highlights text sections while showing predictability, probability, and pattern. The UI is also sleek and quick to give results.
Maybe you could do an accuracy, precision, and recall test 🙂
