#1- Originality.ai (Paid, Best for Pro Web Publishers)

---

Originality.ai was the first pro service on the market specifically built to detect generative AI content and plagiarism at scale.

As a pro web publisher it’s necessary for you to use Originality.ai to ensure peace of mind. This is becauase most freelance writers “write” by paraphrasing and taking from other pages they found on Google,

Start using Originality.ai by taking the content you want to check and pasting it into the editor.

Originality.ai will tell you whether your content is real or fake and whether it’s plagiarized or original.

And they even have a Chrome extension that allows you to check for AI content anywhere you write.

Here’s how I checked one article that I got from my freelance writer, posted it on my WordPress site and was about to hit “publish”.

Needless to say, I requested my writer to rewrite it from scratch until there’s at least 90% human content.

Originality.ai is also a premium plagiarism checker, so to test it I took some content from my guide on the best Quillbot alternatives and told Originality.ai to check it.

Here are the results:

Excellent results!

Originality.ai Content Detector Pros and Cons

Pros

Cons

Who is Originality.ai AI Content Detector Best for?

Originality.ai is the best AI content detector on this list, and I recommend it to all serious publishers who want to keep the integrity of their blogs by not allowing AI content to be published.

Teachers checking the work of their students will also get a lot of value from it, provided they understand Originality.ai is not 100% accurate.

Originality.ai Pricing

Originality.ai pricing model is very simple.

You pay for content scans with credits inside the platform. Each credit costs you 0.01c and each credit lets you scan 100 words of content for either AI content or plagiarism.

Meaning,  if you want to check 100 words of content for both content duplication and AI content that’d cost you 0.02c

Number of Credits	Price	Number of Words	Discount	Discount Price
3K	$30	300 000	25% discount with coupon code "nikolaroza25" (without quotes)	$15

#2- Winston AI (Paid; Best for Pro Bloggers and Web Publishers)

---

Winston AI is also an excellent AI content detection tool. Similar to Originalty.ai Winston AI can check for both AI generated text and duplicate content.

Let’s test it for both.

I again told ChatGPT to write me some content on the topic of the best Quillbot alternatives. Then I ran it through Winston AI.

And the results are excellent. My test content was 100% ChatGPT and sure enough, Winston AI correctly flagged it.

What I like and this is similar to Originalty.ai’s feature, Winston AI shows you the paragraphs and sentences within your text likely generated by AI.

Red is 100% AI text, while other colors signify suspected AI content with different levels of certainty.

Winston AI also offers a premium plagiarism checker, but this feature is only available to Winston AI Platinum and Enterprise plans, so I was unable to test it.

Winston.ai Pros and Cons

Pros

Cons

Who is Winston AI Content Detector Best for?

Winston AI is a premium AI content detector that I recommend to serious web publishers who don’t want to risk their blog’s future with AI generated content.

If that’s you, Winston AI is a good investment for you. And if you go for Winston AI Platinum or Winston AI Enterprise plans you will get access to pro plagiarism checker as well.

#3- AI Detector Pro (Premium, Best for Pro Web Publishers and Students)

---

AI Detector Pro is a new AI detection tool on the market. I tried it and I love it.

Here’s how it works.

First, go here and open up a free account.

You don’t need a credit card to get started with AI Detector Pro.

Second, inside the dashboard click on the “New Report” button and once the new interface loads, paste your desired text into the input field (Note: I took some ChatGPT generated content about Grammarly free trial.

AI Detection Pro can detect all types of GPT content. These are GPT-2, GPT-3, GPT-4, GPT-J and GPT-NEO).

Hit the “Analyze” button and wait while AI Detector Pro does its magic.

Next, you will see the results and you can go deeper by clicking the “View” button in the upper right sidebar.

And here’s what the actual report looks like.

AI Detector Pro correctly concluded that this large paragraph is ChatGPT-generated content.

AI Detector Pro Pros and Cons

Pros

Cons

Who is AI Detector Pro Best for?

AI Detector Pro is an excellent AI content detector that can give you safety and security when it comes to publishing content online.

I recommend AI Detector Pro to serious web publishers who don’t want to risk it with AI content on their blogs. And I recommend this service to students whose universities demand them to turn in human-written content and not AI-generated fluff.

And if you’re a teacher it is paramount for you to check your student’s work for AI plagiarism. But it is also paramount to use a tool that doesn’t give false positives.

AI Detector Pro is such a tool. It’s not perfectly accurate, but it’s close and getting better.

AI Detector Pro Pricing

AI Detector Pro has 3 pricing plans:

There’s also a coupon code MSXOA3 that gives you 50% off the full price for AI Detector Pro Basic and AI Detector Pro Unlimited plans.

Best Free AI Content Detection Tools and Software 2025

#4- ZeroGPT (Free; Best for Casual Bloggers and Marketers)

---

ZeroGPT is a free AI content detection tool that’s well worth your time (but not money given it’s free:) ).

Here’s how it works.

First, copy the content you suspect is created by AI.

Second, go to ZeroGPT and paste that content. In my case, I recently handwrote my Grammarly statistics post. And I wanted to see how ChatGPT would handle the prompt “List me 15 Grammarly statistics and facts“.

So I pasted it into ZeroGPT and hit the “Detect Text” button.

As you can see, the tool is not perfect because it told me my content was 17.9% human, and 82.1% ChatGTP generated.

This is still correct and if you got something like this from your freelance writer, you’d know they’ve been cheating.

And that’s it.

ZeroGPT is able to accurately detect most forms of AI content and I invite you to try out this tool. You’ll be pleasantly surprised like I was. It’s a free service that works.

ZeroGPT Pros and Cons

Pros

Cons

Who is ZeroGPT Best For?

ZeroGPT is a new AI content detector on the market. However, it already has thousands of active users given the tool is free and also it’s able to accurately detect AI content

In my testing (and I tested way more than I showed you above, there was simply no room in this lengthy post) ZeroGPT was successfully able to determine which content is human created, and which came from the hand of a GPT-powered AI writer.

I’m usually hesitant to recommend free AI content detectors because the tools almost always can’t compete with paid solutions.

However, ZeroGPT is an exception to that rule. I recommend it to pro bloggers and even students who need to proof their content against generative AI.

ZeroGPT is a free AI content detector.

#5- Content at Scale (Free; Best for Casual Bloggers and Web Publishers)

---

The third AI content detection tool on this list is Content at Scale’s AI Detector.

This tool is free (find it here) and you can use it by simply pasting the content and hitting the “check for AI content” button.

The tool works better on longer texts (they say at least 25 words) and the limit of content to be scanned is 2500 characters.

Here’s what it looks like.

I’m an affiliate for Quillbot, and I promote it and I recently got my Quillbot discount code article from one of my writers.

Let’s see if the content is AI fake or human-generated.

100% human generated!

This is great stuff.

Now, let’s thy Content at Scale with AI content I generated with Hypotenuse AI, an excellent AI content writer based on GPT-3.

This tool works!

Content at Scale AI Detector Pros and Cons

Pros

Cons

Who is Content at Scale AI Content Detector Best for?

Originality.ai is the best AI content detector on this list, but it’s a paid tool and if you can’t afford it then go for Content at Scale’s AI content detector. It’s one of the best free AI content detection tools on the market.

#6- Writer AI Content Detector (Free; Best for Casual Bloggers)

---

Writer’s AI content detection tool was one of the first to hit the market. It was originally built to detect Openai GPT-2 content and it did that with almost 100% accuracy.

Then when GPT-3 came on the market this tool was still remarkably accurate even though GPT-3 is dozens of times more sophisticated than its predecessor GPT-2.

And now, with the advent of ChatGPT, I was curious so I tested it. Here are a few paragraphs I created with ChatGPT about the best ChatGPT alternatives.

Writer’s tool was near perfect in this test (it was actually 100% AI content and not “just” 98%).

Let’s try human-generated content. I’ll take a snippet of text from my guide on how to get a Grammarly Premium free trial and I’ll paste it into Writer’s online AI detector.

It’s actually 100% human produced content, but 94% score is remarkably accurate.

Writer AI Content Detector Pros and Cons

Pros

Cons

Who is Writer AI Content Detector Best for?

Writer seems like a solid AI writing detector and I recommend it to anyone who cares about not publishing AI content on their blog. It’s free and accurate and the only downside is that you can check only up to 350 words at once.

#7- Copyleaks AI Content Detection App (Free; Best for Casual Bloggers and Web Publishers)

---

Copyleaks is an excellent premium plagiarism checker. And now to keep up with the times they pushed out a free AI content detection tool. You can find it here.

Let’s test it.

I took a snippet of text from my page on the best plagiarism checkers and pasted it here. It’s the content I personally wrote a while back.

And now I went to Writesonic’s ChatSonic and gave it this prompt: “Write me a 100 words on the topic of “best plagiarism tools and apps”

And…

Copyleaks detected paraphrased content as human content. This is a mistake.

Either Quillbot is such an awesome paraphraser, or Copyleaks need to improve its AI content detection tool. Because, although Quillbot doesn’t use GPT technology to generate content, they still use AI (Natural Language Processing and Natural Language Understanding) to paraphrase.

Copyleaks AI Content Detector Pros and Cons

Pros

Cons

Who is Copyleaks AI Content Detector Best for?

Copyleaks’s AI content detection tool is definitely worth using. It’s a free online app that reliably detects GTP-3 content.

If you can’t afford Originality.ai, the best premium AI contact detector, then Copyleaks is an excellent alternative.

Just be aware that this tool is best at detecting Openai GPT-3 content while it may struggle to spot GPT-4 and ChatGPT created text.

Copyleaks AI content detection tool is free!

#8- GLTR AI Detection Online Tool (Free; Best for Casual Bloggers and Web Publishers)

---

GLTR (Giant Language Test Room) is a GPT-2 AI content detector that also works well with GPT-3 and GPT-3.5 (ChatGPT) content too.

The tool at first looks confusing and a mess, but once you figure it out, it can be a great addition to your arsenal of AI content detection tools.

Here’s how it works.

Paste the content into the editor, hit “analyze” and focus on the visual representation as it’s the easiest to grasp.

If most of the content is green and yellow, then it’s probably AI content (green and yellow means content is easily predictable, hence, probably AI generated).

If there’s green and yellow but also red and purple that means content is likely human (red and purple are unpredictable words that are hard to predict and probably human-generated writing).

Here, I told Jasper AI to create some content on the topic of Jasper AI free trial.

Look how it fared in GLTR.

You can see there is a lot of green, and yellows, and almost no red and purple.

It’s clearly AI content.

And here’s another run of my real, personally written Jasper AI free trial article on this site.

The first image is mostly green and yellow, while in the second there’s much more red and purple.

It’s content written by a real human.

GLTR AI Content Detector Pros and Cons

Pros

Cons

Who is GLTR AI Content Detector Best for?

GLTR works superbly at detecting GPT-2 content and is decent at detecting GPT-3 GPT-4 and ChatGPT content.

I recommend GLTR to anyone who can’t afford Originality.ai as using this tool is better than using no AI content detection app at all.

That said, GLTR is one of the least recommended tools on this list.

#9- Hugging Face AI Content Detection Tool (Free; Best for Casual Bloggers)

---

Huggingface is one of the world’s top platforms and communities for machine learning.

And they also have a decent AI content detector. It’s built for GPT-2 but can (pretty) reliably detect GPT-3 and ChatGPT content too.

Here’s some AI-generated content on the topic of Quillbot review (note: I took my own Quilbot review and paraphrased it with Quillbot AI.

And here’s how my Quillbot review that I personally wrote fared when I tested it with Huggingface GPT-2 output detector.

Huggingface seems to work really well and the tool is free.

Huggingface AI Content Detector Pros and Cons

Pros

Cons

Who is Huggingface AI Content Detector Best for?

Huggingface AI content detector is free and that’s a large plus, especially for those who don’t have any money. On the other hand, it’s an older type of AI content detector built to detect GPT-2 generated texts and it struggles with newer versions of GPTs.

And as technology advances this tool is going to become more and more obsolete.

Using Huggingface to hunt for AI content is better than using no too at all, but in general, I recommend you go for a tool that’s more advanced and reliable (Originality.ai is a good example).

#10- GPTZero Free AI Content Detector (Free; Best for Casual Bloggers)

---

GPTZero is a powerful free AI content detector that can reliably detect content produced by BingChat, Google Bard, GPT3 GPT4, ChatGPT, and content that’s a mix of human and AI-generated. The content limit is 5000 characters which is more than 500 words but below 1000 words.

Here’s how to use GPTZero (note: I’ll test it with ChatGPT content, given that ChatGPT is so popular among content creators).

First, I told ChatGPT to write 300 words on the topic of “Best AI content detection tools”.

Second, I pasted the content from ChatGPT into GPTZero, selected that I’m testing ChatGPT content and I accepted their terms of service (just ticked the box).

Then I hit the “get results button.

And here are the results- 100% AI content.

The tool passed the test.

GPTZero also offers a Google Chrome extension which you can install for free to check whether something is AI written on any website on the web.

It’s easy to use Origin by GPTZero.

All you need to do is highlight the text you want to check for AI content, go right click and select “scan with Origin”. And the results will be displayed in the right sidebar. The limit is 5000 characters.

GPTZero Content Detector Pros and Cons

Pros

Cons

Who is GPTZero AI Content Detector Best for?

GPTZero is free and is excellent.

I wouldn’t recommend it to anyone to pick it over Originality.ai, however, if you can’t afford a paid service GPTZero is an excellent alternative.

Benefits of Using AI Content Detectors on Your Content

---

If you’re publishing online and you care about your site’s success, then you must know whether the content you’re showing Google is fake AI content, or human-generated and real human effort.

Here are a few reasons why using AI writing detection tools is just plain smart thing to do:

Best AI Content Detectors in 2025 FAQ

---

#1- Should I Use an AI Content Detection Software?

You need to use an AI content detection software with any content you intend to publish on your blog. If you don’t the risk is you’ll fill your website with AI-generated, fake content, and in the future, this might set you up for a penalty.

You don’t want to be penalized and then have to clean up your entire site.

Pro tip: please keep in mind I’m not advocating for complete ban of AI writing tools usage. No, far from it. If other bloggers start using AI tools in a smart way and you don’t you’ll eventually and inevitably fall behind.

Instead, I advise you to use AI writing tools as assistants to help you consistently write better, faster and with fewer errors and writing blocks.

I also recommend you use HubSpots’s suite of AI tools. HubSpot is a giant in the marketing industry and you can bet their AI tools are always going to be some of the best on the market;  consistently updated, with the newest technology and also deeply integrated with their native publishing platform.

Bottom line is that if you’re going to be using AI writing tools to help you write better then use the best tools currently available on the market, and HubSpot’s AI writing tools are clearly the best.

#2- What is the Best AI Content Detection Tool?

The best AI content detection tool is Originality.ai. Based on my testing it’s nearly 100% accurate in spotting AI content and it comes with a grammar checker and plagiarism checker tool.

Read my best grammar checker software guide next!

#3- What is the Best Free AI Content Detection Tool?

The best free AI content detection tool is Content at Scale’s AI output detector.

Based on my testing it’s nearly 100% accurate with GPT-2 GPT-3 and ChatGPT AI content.

#4- Can Google and Other Search Engines Detect AI Content?

Google and other search engines can detect AI content. The proof of that is that AI content farms got destroyed in a recent HCU (Helpful Content Update).

Here’s an example:

#5- How Can Google and Other Search Engines Detect AI Content?

It’s a secret how Google and other search engines detect AI content. It’s probably the combination of techniques, like monitoring stylometry, checking author vectors, and using GPT analogue algorithms to see whether the text is predictive.

These are my best guesses at the moment, however generative AI technology is not a secret to Google, they have it and also have the means of detecting it.

#6- Will I Get Penalized for Using AI Content on My Site?

You will get penalized for using AI content on your site IF all you do is post AI content at scale.

For example, throughtheclutter.com is an AI-generated site that had explosive growth because of extreme content velocity, but when the HCU update happened the site got annihilated.

Moreover, you will not get penalized for posting AI content on your site if your article is mostly human-written with a touch of AI.

#7- Can AI Content Detectors Detect Paraphrased Content?

AI content detectors can detect paraphrased content, especially if you use GPT-based tools to paraphrase.

But even if you don’t, your content will probably be detected.

For example, Quillbot uses its proprietary AI (NLP+ NLU technologies) to understand and paraphrase the content.

But some (not all) online AI content detection tools and software can detect content paraphrased with Quillbot.

For example, here’s a snippet of my Jasper AI pricing guide which I paraphrased in Quillbot.

And here’s from Writer’s free AI text detector tool:

Bottom line– don’t rely on paraphrasing alone as some tools can already detect it, while Google certainly can.

Read my guide on the best AI paraphrasing apps and tools next!

#8- Can Grammarly Detect AI Content?

Grammarly cannot detect AI-generated content because it is not designed as an AI content detection application.

However, it’s worth noting that Grammarly recently introduced GrammarlyGO, a generative AI writing assistant powered by technologies like ChatGPT and GPT-4 from OpenAI, which could potentially be recognized as AI-generated content.

#9- Are AI Content Detectors 100% Accurate and Reliable?

Currently, AI content detectors are neither 100% accurate nor 100% reliable.

This is because AI content generation is a new field and detecting such content is an even newer endeavor. To address the evolving challenges of AI content detection, partnering with an experienced artificial intelligence development company is instrumental.

There are even articles that claim 100% AI text detection is impossible.

In other words, with all of these tools, false positives are possible, and you should always take the results with a grain of salt.

#10- How to Reliably Detect AI Generated Content?

Detecting AI-generated content reliably can be challenging due to the advanced capabilities of modern language models. Here are some approaches and considerations for detecting AI-generated content:

1. Language Patterns and Unusual Syntax: AI-generated text may exhibit unusual syntax or language patterns that differ from typical human-generated content. Look for inconsistencies, unnatural phrasing, or overly formal language.
2. Contextual Understanding: Compare the content against its context and intended purpose. AI-generated content might lack depth, relevance, or understanding of specific topics or contexts, which can be indicators of automated generation.
3. Repetition and Consistency: AI models sometimes repeat phrases or concepts in a way that appears unnatural or overly consistent. Humans tend to vary their expressions more naturally.
4. Knowledge of Current Events: AI models may lack up-to-date knowledge of current events or may provide outdated information when queried about recent developments.
5. Tool Detection: Some AI-generated content may explicitly mention tools or technologies like “GPT-3” or “ChatGPT,” or include trademarks or disclaimers related to AI generation.
6. Style and Tone: AI-generated content may exhibit a consistent style or tone throughout, lacking the variability that is typical of human communication.
7. Evaluation Tools: Various tools and techniques are being developed to detect AI-generated content, although their effectiveness can vary. These tools may analyze patterns in text, detect inconsistencies, or use machine learning algorithms to identify automated content.
8. Metadata and Source Verification: Check metadata, timestamps, or source information if available. AI-generated content may lack coherent metadata or may come from sources known to use AI extensively.
9. Human Review and Judgment: Ultimately, human judgment remains crucial for detecting subtle nuances and inconsistencies in content that automated tools may miss.
10. Legal and Ethical Considerations: Consider legal and ethical implications when detecting and attributing AI-generated content, especially in contexts where transparency and authenticity are critical.

As AI technologies evolve, so too will the methods and tools used to detect AI-generated content. Staying informed about developments in AI and computational linguistics can also aid in developing effective detection strategies.

#11- How to Reliably Detect GPT-J AI Generated Content?

The only way to reliably detect GPT-J AI generated content is to use AI content detection tools, both free and paid services.

Paid apps are better.

#12- How to Reliably Detect GPT-Neo AI Generated Content?

The only way to reliably detect GPT-Neo AI generated content is to use AI content detection tools, both free and paid services.

Paid apps are better.

#13- How to Reliable Detect GPT-2 AI Generated Content?

The only way to reliably detect GPT-2 AI generated content is to use AI content detection tools, both free and paid services.

Paid apps are better.

Learn more about GPT-2 by reading my GPT-2 statistics guide next!

#14- How to Reliably Detect GPT-3 AI Generated Content?

The only way to reliably detect GPT-3 AI generated content is to use AI content detection tools, both free and paid services.

Paid apps are better.

Learn more about GPT-3 by reading my GPT-3 statistics guide next!

#15- How to Reliably Detect GPT-4 AI Generated Content?

The only way to reliably detect GPT-4 AI generated content is to use AI content detection tools, both free and paid services.

Paid apps are better.

Learn more about GPT-4 by reading my GPT-4 statistics guide next!

#16- How to Reliably Detect ChatGPT AI Generated Content?

The only way to reliably detect ChatGPT AI generated content is to use AI content detection tools, both free and paid services.

Paid apps are better.

Related: read my ChatGPT statistics guide next!

#17- Can AI Content Detector Tools Detect Bing Chat Generated Content?

AI content detectors can detect Bing Chat-generated content because Bing Chat is currently powered by GPT-4, and GPT-4 generated content regularly gets flagged by Originality.ai, the best AI content detector on this list.

Learn more about Microsoft Bing and Bing Chat by reading my Microsoft Bing statistics and Bing Chat statistics guides next.

#18- Can AI Content Detector Tools Detect Google Bard (Gemini) Generated Content?

At this point in time it is unknown whether AI content detectors can detect Google Bard generated content (Google Bard is powered by Language Model for Dialogue Applications, LaMDA). This is because Bard is not available yet and no one’s trying to create content with this type of artificial intelligence.

I’ll update my guide as soon as I can do some testing with Google Bard.

Update:

First, I told Google Bard to generate some content on the topics of “Google Bard”.

Second, I took that content and run it through Originality.ai.

Here are the results:

Originality.ai is the best AI text detector on this list and it can easily detect Brad-generated content.

#19- Can AI Content Detector Tools Detect Anthropic Claude Generated Content?

Anthropic Claude generated content seems to still pass under the radar of most AI content detectors.

For example, I told Claude to generate 200 words of content for me.

Then I ran that text in Originality.ai and the tool told me human wrote.

Next, I tried the same with AI Detector Pro and it too told me it’s human-written content.

Learn more about Anthropic Claude by reading my Anthropic Claude statistics guide next.

#20- Is There an AI Content Detection App That Can Scan an Entire Site for AI Generated Content?

Currently, no AI content detection app has the ability to scan entire sites for AI generated content.

However, Originalty.ai are advertising that soon their AI detector tool will boast that ability.

Stay tuned!

#21- Can Turnitin Detect AI Generated Content?

Turnitin can detect AI generated content.

They can detect with 98% accuracy GPT-2, GPT-3, GPT-4, and ChatGPT content. Turnitin can also detect content generated by older models like CPT-J and CPT-Neo.

#22- Can I use Two AI Content Detectors Instead of One to Check My Content?

You can use two AI content detectors instead of one to check your content. In fact, I recommend it, especially on the most important content on your blog, or any other type of online written work.

Using two tools will give you a clearer picture of whether something is AI generated text or not.

For example, I recently found a blog post linking to one of my Quilbot articles. The content sounded weird and stilted and I had my suspicions so I checked it in the Content at Scale AI content detector.

Here are the results:

And here’s the same text sample run through Originality.ai:

As you can see, Originality.ai found 100% AI content while Content at Scale found none!

#23- What is the Best ChatGPT Detector on the Market?

The best ChatGPT detectors on the market are Originality.ai, Winston.ai and AI Detector Pro.

Some of the free detectors can also discover ChatGPT content quite easily, but the accuracy is far lower and the risk of false positives is very high.
