As technology advances, AI-generated content is becoming more sophisticated and harder to detect. The launch of ChatGPT on November 30, 2023 has changed the content creation process by making generative AI accessible to all for free.
Another element to consider is how powerful and genuinely good generative AI has become. ChatGPT writes better content than most humans in a few seconds.
In order to maintain the integrity of writers but also in education, it is crucial to have reliable AI content detectors available. This article will provide a comprehensive list of the top 10 best AI detection tools, allowing you to choose the best solution for your content analysis needs.

Bottom Line: Writer is easy to use and quick to make a light AI detection scan.
4. OpenAI’s AI Text Classifier
Summary: Developed by Open AI, this detection tool is surprisingly very rudimentary. It provides a very high level assessment on the likelihood a given text was generated by AI or not. They have a few labels, including very unlikely, unlikely, unclear, possibly, or likely AI-generated. You’ll need a minimum of 1,000 characters to process your scan. Our internal testing team was able to easily bypass this tool.
- Free, but you’ll need an Open AI account.
- Simple to use
- Very high level assessment.
- Easy to bypass.
- Doesn’t give you any guidance.
- No highlights of sentences likely generated by AI.
Bottom Line: We had high expectations of the tool developed by Open AI to detect its own content, but our experiments were extremely disappointing. We were able to easily bypass this detection tool with various prompts, and slight paraphrasing.
5. Hugging Face GPT-2 Output Detector
Summary: Hugging Face is a leading provider of AI tools and services for natural language processing and machine learning. AI content detection is increasingly prevalent, and Hugging Face is a pioneer in this field, nevertheless it is a tool that was trained on GPT-2 data.
- Fast and simple to use
- Trained on GPT-2
- Does not detect new LLM’s such as Claude
- Extremely easy to bypass with advanced prompts
Bottom Line: Hugging Face’s AI detector is one of the first to make its appearance, however there have been many developments in generative AI that raised the bar for AI detection in the past few months.
6. Draft & Goal
Summary: Draft & Goal is a content generation tool that utilizes AI to create unique articles on various topics. They recently developed an AI Content Detector feature designed to ensure the originality of the generated content.
- Supports multiple languages (French and English for now, more to come)
- Easy to use
- Low detection rate
- Several events of false positives reported.
- Requires 400 characters to scan.
Bottom Line: Draft and goal offers a simple and intuitive user interface to quickly scan content for AI. They are working on a much needed improvement of detecting AI generated text in other languages than English.
7. Writefull GPT detector
Summary: Writefull is a cutting-edge tool created to aid writers, especially those in academia, in their writing. It provides a range of valuable features such as a paraphraser, abstract generator, title generator, and sentence palette. The platform’s primary goal is to assist users in producing top-notch, well-organized content while minimizing the time and effort required. They’ve also deployed an AI detector.
- Detects ChatGPT content very well
- Generous Free Trial
- Can be bypassed with paraphrasing tools such as Quillbot.
- Doesn’t seem to be trained on new LLM’s such as Claude and Bard.
Bottom Line: Writefull is a great AI writing tool for academia overall, however their AI detection capabilities offer a very surface level detection.
7. GPT Zero
Summary: One of the platforms that have received the most press attention is GPT Zero. They offer an excellent free trial and an easy to deploy API. Users can batch upload files in .pdf, .docx and .txt. GPTZero also has a Chrome Extension used by many of its users.
- Free trial
- Easy to deploy API
- Paid plans are fairly priced
- Chrome Extension
- File upload features
- Mixed review on their detection model
- Limited detection with Free Trial
Bottom Line: Given the press received by GPTZero, we had really high expectations for their software. Their software is well built and the API access is easy to deploy. We also found their pricing was quite reasonable. Unfortunately, we found their detection capabilities lacked accuracy as did a few other publications.
8. Zero GPT
Summary: Although the name is almost identical to the aforementioned detection software, ZeroGPT is a different organization. ZeroGPT is a quick and free easy to use tool for AI detection. Their revenue model is based on Ads.
- Extremely Easy to use
- No need to create an account
- File Upload capabilities
- Limited AI detection capabilities
- User Experience contains banner ads
Bottom Line: Although many people confuse GPTZero with ZeroGPT, this platform is a lot more straightforward and simple to use. We would recommend it for a very summary assessment.
9. Copyleaks AI detector
Summary: Copyleaks is another legacy plagiarism detection software that has been around for a long time. You can run a surface level content scan without creating an account. They also have a great Chrome Extension. Their results include a simple assessment and contains several “locked” assessments, potentially due to an upgraded feature.

Bottom Line: The Copyleaks platform is already used by several entreprises, making them well equipped to tackle the AI detection wave. We found their assessments unclear and the free version quite limited.
10. AI Detector Pro
Summary: AI Detector Pro has a complete solution for AI detection, along with a very interesting feature to “suggest” alternate content that would potentially be able to bypass AI writing detectors. Their free trial comes with 3 document scans, and without the “ai rewriter” feature. Nevertheless, their capabilities and assessments were on point.
- Accurate detection
- Project and file management
- AI rewriting feature
- Money back guarantee
- Pricing structure makes it costly
- User interface
Bottom Line: AI Detector Pro has a really interesting business model where they complement their AI detection with AI re-writing to essentially bypass AI detectors.
AI detection FAQ
AI content detectors have been created to discern human-generated from machine-generated content. Among them, Winston AI stands out with an impressive detection rate of 99.6% when it comes to identifying AI-generated content produced by ChatGPT, GPT-4, Bard, and other commonly used AI text generation tools.
As the technology advances, it is anticipated that AI detectors will become increasingly precise, thereby playing a crucial role in safeguarding the genuineness of online information.
AI content detection leverages natural language processing, machine learning, and deep learning techniques to examine textual content and ascertain its origin as either human-generated or AI-generated. Through this process, the AI system familiarizes itself with the intricacies of human language, discerns distinctive patterns that distinguishes human and AI writing, makes predictions regarding new text, assigns a score that assesses the probability of human or AI authorship, and consistently enhances its performance through regular updates and refined training data.
Because of its 99.6% accuracy rate in detecting AI generated content, Winston AI is known to be the best AI detector for both institutions and publishers.
An AI content detector is a software application designed to assess the authenticity of a text by distinguishing texts generated by AI writing tools like ChatGPT and those written by humans. They rely on extensive datasets and various additional criteria to deliver this assessment.
The rise of AI text generators has sparked concerns regarding their impact on search engine optimization (SEO). The potential proliferation of low-quality spam generated by AI poses a threat. However, search engines such as Google are actively enhancing their algorithms to effectively identify and address such content.
