5 Best AI Content Detector Tools for 2024

People are talking about how hard it is to tell if something was written by a person or by AI. They're discussing different AI tools that try to figure this out, but many of them aren't very accurate and can give wrong results. This article gathers information from various sources and experts to help you understand these AI tools better. Keep reading to find out about the top 5 AI detectors for 2024.

What is AI detection?

AI content generators like ChatGPT, Jasper, and Bard are trained on big collections of text and code. They can make different kinds of creative texts and copy how humans write. On the other hand, AI detector tools try to figure out if something was written by AI. They look at the text for certain patterns and qualities that suggest it was made by AI.

AI detection involves determining whether content is created by AI or humans, often using a special tool that employs machine learning and natural language processing. These tools spot patterns in the text. If the content follows a clear pattern, it's likely AI-generated.

These tools don't understand word meanings but analyze context. For instance, they look at the words before and after to predict what comes next. If the next word is highly predictable, the text is probably AI-generated. Human writing tends to be more varied and creative.

Let's simplify with an example.  If someone types "Kittens are so cute" into the tool, it looks at the words before "cute" to guess what might come next. It's likely to think "cute" is coming next, rather than other words like "fluffy" or "soft." This kind of sentence is very common, so the tool might think it was made by AI. While this example is basic, AI detection tools handle more complex text to make classifications.

As AI gets better, these detector tools will probably improve too. Eventually, they might not only spot AI-generated content but also figure out which specific AI made it.

Best AI Content Detector Tools for 2024

As AI gets better, it's really hard to tell if something was made by a human or AI. That's where AI detection comes in – it checks texts and pictures to see if they were made by humans or AI. 

Here are the 5 Best AI Content Detector Tools for 2024, listed without any specific order.

Winston AI

Winston AI is a tool in the cloud that can spot content made by AI. It helps businesses find AI-made content in their marketing, customer service, and other messages. It has useful features like a quick check, file uploads, project and team management, support for different languages, printable reports, and a plagiarism checker.

This tool aims to stay ahead in detecting AI-generated content. It's equipped with a big dataset to reduce mistakes and gets updated weekly to maintain its effectiveness. It claims it's super accurate, with up to 99.6% precision. However, another source, Scribbr, says it's only around 84% accurate.

Copyleaks AI Detector

Copyleaks stands out for its careful examination of individual sentences to determine if the text is authentic or not. It helps users by showing where passages might be written by humans or by AI, and it can even point out sections that seem like they've been rewritten to hide that they're generated by AI.

One cool thing about Copyleaks is that it can spot code written by AI, like from GitHub or Copilot, in 30 different languages. It also marks text to show if it's written by a human or a machine. And it doesn't just look for obvious AI-generated text; it can also find content that's been copied or slightly changed.

According to Copyleaks, their AI detector is accurate, with a reported accuracy of 99.1% and a very low false positive rate of 0.2% for AI-generated content. It's highly rated by users, getting 4.7 out of 5 stars on G2.

However, Medium tried out this tool and discovered that it's not effective at identifying AI-generated content. Specifically, it only recognized 50% of the AI-generated samples as such. This tool fails to detect modern AI-generated content, like that produced by ChatGPT. It may have been useful before models like ChatGPT were around, but it struggles with content generated by ChatGPT, which is now quite common.

On the bright side, it can accurately identify human-written text as such, although it does make some errors in doing so.

Content at Scale

Content at Scale is handy for businesses to catch AI-made content in things like ads, customer chats, and company messages. Using this tool is pretty straightforward. You can just copy and paste text or upload a file onto its website. Then, the tool checks the text and tells you if it seems like AI wrote it.

If you pay for Content at Scale, you get extra perks. You can check as much AI content as you need, even if it's disguised. Plus, you get credits for making AI-written parts look human, and you can ask for help with lots of rewriting. There are more features too, like checking web pages and getting detailed reports.

This tool claims to be super accurate, saying it catches AI content 98% of the time. But tests from ZDnet found it was only right 66% of the time, showing a big gap between what it says and what it does.

Originality AI

Originality.AI uses AI to check for both plagiarism and AI-generated content. The tool then goes through your text, spotting any parts created by advanced AI models like ChatGPT and Bard, as well as any copied content.

It has lots of ways to check text, including a Chrome extension, scanning websites directly, and uploading files like documents or PDFs. It works with many languages and focuses on making it easy to share reports with others. This tool claims to be very accurate, detecting AI-generated text with over 95% accuracy, and it's also fast to quickly analyze text.

GPT Zero

GPTZero is a free tool that spots AI-generated text. It's easy to use just like any other AI detector, just paste your text and it quickly tells you if it's AI-generated. It's designed to catch content from specific AI models like ChatGPT, GPT 3, GPT 4, Bard, and LLaMa.

It offers a detailed dashboard with visual summaries and stats. It color-codes text and provides detailed linguistic analysis, making it useful for both casual users and researchers.

However, it's not as accurate as some other AI detectors, scoring only 52%. Also, it labels text as AI-generated without providing gradations.

Final Thoughts

As AI tech gets better, so will these detection tools. Keeping up with the latest improvements and picking the right tools will help you stay on top of changes in content creation. Remember, AI isn't meant to replace human judgment but to make things clearer and encourage honesty and originality in writing.
