Best AI Detectors in 2025 

© by Innova Labs from Pixabay

Every day, I am faced with new headlines that remind me just how much AI has taken over. You don’t know what AI is? Well, let me tell you. AI stands for artificial intelligence. This newfound technology started becoming mainstream in about 2020 when a San Francisco company known as OpenAI released its GPT software to the world.

Since then, the world has seen AI take over, and today, I want to chat about the best AI detectors in 2025. These AI Detector systems are the only creations right now that help me figure out which content I am devouring is created with AI technology or a human being. 

  1. AI Detector
  2. TraceGPT 
  3. Winston AI 
  4. Hive 
  5. GPTZero 
  6. Originality.ai 
  7. Smodin 
  8. Quillbot
  9. Grammarly 
  10. Surfer AI content detector

Just so you know, these systems are still a little clunky. AI detection software must learn from the data you put into it so that it can get better and better at deciphering AI content, but I can say it’s a great starting point for those who want to know if what they’re reading is AI content or human created. 

What are AI detectors? 

I suppose before I share the best AI detectors of 2025, you probably want to know what these programs are and how they basically work. Well, let’s get started. AI detectors are a piece of technology that uses the same machine learning programming that AI writers use. 

This technology reverse engineers a piece of content to evaluate a few programmed parameters to see if the content is more than likely artificially created or drafted by a human. These parameters are similar to what the other AI programs use, so essentially, this AI detection asks if the text could have been created by its lovely sister AI writers or not. If yes, then the percentage will come back to you telling you that this content is X percent more than likely created by artificial intelligence.

Remembering that this software is used as a baseline to determine if the content will pass the checkers, versus if it was really created by AI. Once you get your percentage, we advise you to have a little meeting with your team to discuss whether AI was utilized or not. Below, we will chat about each of the best AI detectors for 2025 in more detail. 

Who can use AI detectors? 

Anyone can use an AI detector to determine if a piece of content is developed by an AI writer or human being. You simply copy and paste a piece of text into the text box on the AI detector’s website and click a button.

The program will run behind the scenes and in a short time it will provide you a report on what percent risk the content is at being developed by an artificially intelligent writer or a human being. With this percentage, you can then evaluate the content with your human eye to see whether or not you truly feel the content is Ai developed.

Over time, we will see that these detection models are more intelligent, but for now, they are the best option for evaluating text and images. This software gives us a starting point to have a chat about AI-drafted content and what to do with it from here. Each of the best options do have additional features, premium options, and unique settings that help each stand out as a reasonable option to use in 2025. 

Can AI detectors handle a heavier workload of analyzing text? 

In this example, I wanted to touch on the subject of using this AI detector software for larger work orders. For example, if you’re a content creator, you may need to work with larger word count orders than the average person.

This is where we wanted to check if each detector could handle scaling up from the beginning stages with you. It’s best that you check the AI detector program before choosing the best AI detector for your business use.

Some of the detection models can handle a maximum of 1,500 words, while others may handle less. The key is to know your needs and the limits of each of the best options featured here today. 

As this technology continues to expand, you will find that larger scale models of AI detection software will become available to the masses. With that said, AI is starting to become more human sounding even with the humanizer tools that some software offers which makes it even more difficult for the detectors to determine which piece of content was created with AI and which was made to order by a human being. 

While some content firms don’t mind having AI content drafted for their websites, others do mind. This is why there is a market for AI detectors. These are a good starting point for people who want to make sure their writers and developers are using their minds and creativity to draft content. 

These detectors will provide you with a solid standpoint to determine if the person used any AI software or not. The biggest tip we have for you is to keep in mind that these detectors can give false positives. This means it could say it’s AI drafted, but the writer is trained in SEO content strategy growth which means they tend to write more robotically.

Just consider the whole picture when determining if a writer used AI software or not after you get the percentage back from this AI detector. Over time, I know that these detectors will become far more reliable, so let’s just keep using them so that our friends who don’t like heavy AI content on their platforms can have a more reliable way of checking their writer’s work in the future. 

I want to make sure I share more details about each of the options I feel made the list for 2025. Below you can find the details on each of the best AI detectors that I feel are going to win big this year. I tried to share this list in the order of favorite to least favorite, but each does provide various additional tools that I see as helpful in the writing industry. 

AIDetector.com

This detector can determine if your content is developed by AI using any of the generators like ChatGPT, Gemini, and other platforms like Jasper that some writers often use to create content. This is rather helpful since the GPT systems are by far the more popular budget-friendly writing option for most freelancers. 

AIDetector.com also features some amazing tools, like the humanizer tool, which can tell you if an image was AI-generated. This program will only advance as it continues to rank among the top options to use in 2025. 

TraceGPT 

This option is another great detection software to consider. You can pay $5.99 per month for checking up to 20 pages of content that has approximately 275 words per page. This may not be cost effective for larger scale operations. However, it’s an excellent beginner option for the average person who wants to check a piece of content every so often. 

That said, this does have an authorship verification tool and plagiarism checker that you could test while using their service, too! 

Winston AI

This AI detector makes the list for plenty of people have enjoyed using it, but it doesn’t do well with some AI generated content. If the content is drafted by Claude, then chances are it will slip by the detector software within Winston AI as of today. 

You can test this software out to see how well it does today because every piece of AI software becomes better with more data we input. The more we use this detector, the better it will be at predicting AI content creation. 

Hive

Next up on our list of the best AI detectors in 2025 is Hive. This is a free AI detection software that may change in the future as more people become privy to the service, but right now their Chrome browser extension is an amazing addition and they do have a decent plagiarism checker if you’re interested. 

GPTZero 

Another option that we found is this GPTZero which is a little clunkier than the above options we featured. This also had a difficult time detecting text created with Claude, but it did well overall with the rest of the AI tested content. This does have a service option that allows you to test beyond 10,000 words per month. You can peek at their website to see what their current tier levels are for their paid options. 

Originality.ai

This AI detector is another reasonable option available to those who want to check GPT content. If you want to determine Jasper, Claude, or Gemini content then perhaps you won’t want to use this software. The readability check with this AI detector is pretty nifty!

You can determine how good the readability is of your text. This refers to how well the text can be read by the user. Oftentimes, we write on a level that makes sense to us, but when someone reads that content back or to themselves, it may sound weird. The reality with Orginiality.ai is an added bonus we recommend you check out. 

Smodin

Smodin is the least favorite on my list here, but we wanted to include another reasonable option for you to try. This doesn’t detect Claude content, which means it also doesn’t fare well with content created by Jasper, or Gemini either. 

The GPTs are safe with Smodin, it seems to know when that content was used. This AI detector does come with a free use option for about five weekly uses but after that, you’ll be asked to pay a monthly fee. 

Quillbot

This is a fun AI detector that can test up to about 1,200 words for free. This is another unreliable option, though, for it has given us false positives for AI detection. I’ve had it determine my human content developed by myself as an AI creation.

Just be careful when using something like a free version of Quillbot for your AI detection. You can review their premium options to see if they bode well for you. 

Grammarly 

Grammarly isn’t another option that many writers use to check their grammar and spelling, but it is quickly becoming a popular option for AI detection. You can use their plagiarism checker and reality to determine if the content you want to check is written by an AI program. 

The fees vary with Grammarly. It’s best that you visit their website to see their latest offering and premium level plans before choosing this option. Their current annual plan seems to be the best deal as of the time I wrote this article. 

Surfer AI content detector

This AI content detector from Surfer is another advanced SEO program that wanted to get on the AI detection bandwagon. They feature an option to help you check a minimum of 100 words at a time with a maximum allowance of 500 words.

If you want to check more than that, you must pay for their premium plan, which offers some decent SEO tools to use alongside their AI detection software. 

There you have it, the best AI detectors in 2025 that can help you evaluate text and, in some instances, AI generated images. This is a brilliant way for people to determine what text they are consuming, but it also helps content management firms stay on the up and up with their content writers.

These detectors can help your company keep its AI policy in good standing with the writers who are hired to abide by the terms of the agency. Using each of these options will help train the AI detector software to become more intelligent and reliable over time. Remember that AI learns through machine learning, which means the more data it consumes, and the more feedback we provide, the more accurate and available these tools will become.
