Artificial Intelligence (AI) has become a double-edged sword in content creation and management. On one side, AI writing software and content generators are considered to be invaluable for producing and optimizing content quickly. Conversely, AI content detectors help ensure that AI-generated content isn’t plagiarized and reads more like a human rather than a machine. This article delves into this dichotomy of AI-generated content and AI content detection, emphasizing the best AI content detectors for you to try.

Finding reliable tools can be a challenge. We’ve put together a list and review of the best AI-catching software. Starting with Winston AI, here’s our list of top detection products to consider:
The Best AI Content Detectors Listed In Order
1. Winston AI
🥇 Best Dedicated AI Detector
Winston AI is arguably one of the best AI detectors for written content. Its whole purpose is to tell the difference between human-written and AI-written text, and it does so with 99% accuracy for ChatGPT, GPT-4, and Bard (based on their internal testing). It has one of the easiest-to-use UIs of similar tools and allows you to save reports to return to your results without re-running the test.
Since Winston AI’s sole purpose is to help users detect AI (other tools also offer AI content generation), it brings a lot of tools to the table that are of exceptionally high caliber. Its AI detection pools sections of a text into Likely AI-generated, Possibly AI-generated, and Unlikely AI-generated and color codes each line. It also detects and reports on plagiarism, providing what text was plagiarized and its originating source.
What We Like About Winston AI
- Highly Accurate AI Writing Determination: Winston AI excels in accurately identifying potential AI-generated writing.
- Advanced Plagiarism Detection and Readability Results: It features sophisticated tools for detecting plagiarism and analyzing the readability of content.
- Team Plan for Shared Workspaces: Winston AI offers a Team Plan that allows multiple users to share a workspace for collaborative efforts.
- OCR Scanning for Checking Text on Images: Able to scan images for any text using OCR and then put that text through content detection.
What Could Be Improved
- Start Scan from URL: It would be nice to start a scan with content from a URL instead of copying and pasting or using its separate Chrome extension.
- Add More Credits for All Plans: We’d like to see the ability to purchase extra credits for every tier, not just the Elite tier. Some might not need the team features but would like more detection credits.
🥇 Why We Picked It
Of AI detectors, Winston AI has the cleanest and easiest-to-use dashboard. It also does an excellent job with AI content detection and lets you know the possibility of any matches, line by line. It’s reliable and a pleasure to work with.
If you want more information about how it works, see our detailed Winston AI Review.
Who Is Winston AI Best For?
Winston AI is the go-to AI detection tool for those who need multiple file types and formats scanned. It supports pasted text, images with optical character recognition (OCR), and uploaded documents (PDF, Word, etc.). It even doubles as an advanced plagiarism detector against submitted text.
Community Reviews and Ratings
While it has not garnered many reviews online, Winston AI has a reputation for innovating faster than many competitors. It’s successfully kept a good product that works decently well, even against advanced LLMs such as GPT 4 and Claude 2.
Pricing
A free plan with limited credits is available, with paid plans starting at $18 per month.
2. Originality.ai
🥈 Best AI Detector with Fact-Checking
Originality.ai is a leading tool that helps make content detection easy and reliable. It’s a favorite among users for its ability to accurately identify AI-generated content, ensuring the authenticity and originality of written material. This tool is excellent for spotting AI-generated content in real time. It’s a valuable asset for anyone who needs to verify the authenticity of their content quickly. Its speedy yet reliable analysis makes it a capable partner for preserving the integrity of the content you publish.
Originality.ai lets authors scan any content. They can enter it onto the website’s front end, connect its API, or check content on specific URLs. Originality.ai also has a Chrome extension, which means you can take text analysis on the go—wherever you are browsing. Best of all, all content gets scanned to determine the likelihood of it being written by AI or if it was plagiarized. It even checks the readability level and throws in some fact-checking, too.
What We Like About Originality.ai
- Industry-Leading Accuracy: Originality.ai is known for its industry-leading accuracy in detecting AI-generated content.
- Real-Time AI Content Detection: It offers real-time detection capabilities for identifying AI-generated content efficiently.
- Convenient Google Chrome Extension: Originality.ai provides a convenient Google Chrome extension for easy access and use anywhere.
- AI and Human Text Breakdown: The tool offers a detailed breakdown differentiating AI-generated text from human-written text.
- API for Text Analysis at Scale: Originality.ai features an API that allows for text analysis at a large scale, catering to extensive content needs.
What Could Be Improved
- Cluttered UI: Working inside of Originality AI is a little cluttered, making it harder to find tools the first few times you use it and otherwise being a little distracting.
- Scanning Time: It takes upwards of a minute to perform a scan, even for a word count of less than 1,000 words.
🥈 Why We Picked It
Originality offers many tools under one roof, especially for monthly subscription users. We like that it gives confidence-based scoring for AI detection reports and highlights lines of copy by percentage of AI origin likelihood. Other tools mark the obvious sentences while using a label for questionable content, saying that it could be AI-generated. Originality gives a percentage likelihood (90% likely, 80%, etc.), which inspires more confidence in the results.
Who Is Originality.ai Best For?
Originality.ai is an excellent tool for content creators, editors, and digital marketers who need to check the originality of their content quickly. Its real-time detection makes it a valuable tool for those working in fast-paced environments where time is crucial. It’s perfect for digital marketers who must ensure their content is unique to uphold their brand’s reputation and SEO rankings. It also has user seats that allow teams to work more efficiently.
Community Reviews and Ratings
Originality has few online reviews, but potential users can search social sites to see what regular users say. All in all, people like Originality’s credit system, which lets them buy credits as needed. They also appreciate the extra tools, besides AI detection, that Originality has added.
Pricing
Monthly pricing starts at $14.95, with pay-as-you-go credits at $30.
3. GPTZero
🥉 Best AI Detection for Specific Models
GPTZero is a tool designed with simplicity of use in mind. Primarily built for educators and educational institutions, GPTZero has plenty of academically minded anti-plagiarism tools built in. This tool is designed to provide a simple solution for detecting AI-generated content. Its simple approach may be ideal for some but too simplistic for others (however, its integrations with LMSs and MS Word are anything but simplistic).
What We Like About GPTZero
- Stripped Down UI for Simplicity: GPTZero boasts a streamlined user interface for straightforward AI text checking.
- Quick Content Check for Specific Models: It provides rapid content analysis, focusing on specific AI models like GPT-3, Bard, etc.
- MS Word and LMS Integrations: GPTZero integrates seamlessly with Microsoft Word and various Learning Management Systems (LMS) for enhanced usability.
- Advanced Google Doc Tools: GPTZero interprets the history of how content gets added to a document to determine if a person wrote it or pasted it in. Mixing user history with AI detection creates a reliable way of checking students’ work. Students may also use it on their end to create videos of the document as they work to disprove the use of any AI tools if they come under any scrutiny.
What Could Be Improved
- Detect More Models: It would be nice if GPTZero provided more tuned models to check against, like Claude 2.0 and Gemini.
- Plagiarism Detection: With educators and educational institutions in mind, it’d be nice to include plagiarism detection to save costs using only one tool.
🥉 Why We Picked It
Since this product focuses on educational use cases, the fact that AI content scanning can be done inside a Word or Google document can save a lot of time for teachers and teaching assistants. Its integration into mainstream LMSs such as Canvas and Blackboard also makes using it in a grading workflow much simpler and more scalable. And its API makes it extensible to other custom workflows as well.
Who Is GPTZero Best For?
GPTZero is ideal for educators and department heads researching AI use in academic work. Its clean design makes it an excellent choice for those who are new to AI content detection and want a tool that’s easy to use. GPTZero uniquely helps educational organizations manage the shift into the future of AI.
Community Reviews and Ratings
Users enjoy GPTZero’s free plan that gives 10,000 monthly credits. Integrations with LMS grading workflows provide a natural way of using the tool without adding more time to teachers’ plates.
Pricing
Free to use on their website, with paid plans and increased limits starting at $15 per month.
4. Sapling AI Detector
Sapling, known for its many other AI tools, also offers an AI content detection tool. This tool provides a highly accurate solution for detecting AI-generated content. Its ability to see AI-generated content with as little as 50 words makes it a reliable tool for those who work with short-form content. Moreover, its color-coded results make it easy for users to interpret the results, making it a user-friendly tool for ensuring the originality of your content.
A subscription provides access to the AI content detector and sentence autocomplete (plus more). Built for customer support and sales teams and the unique work they do with content. It creates full reports on how agents use AI to help in coaching and training to improve over time.
What We Like About Sapling AI Detector
- Overall Inauthentic Content Percentage: Sapling AI Detector offers an overall percentage indicator for identifying the extent of inauthentic content in a document.
- API Access for Bulk or App-Based Content Checking: The tool provides API access, enabling bulk or application-based content checking for scalability and integration.
- Functionality within CRMs and Email Clients: Sapling AI Detector works seamlessly within Customer Relationship Management (CRM) systems and email clients, enhancing its usability in business contexts.
Sapling offers another excellent option for AI content checking. It also has a helpful browser and API for extended use.
What Could Be Improved
- Dated UI: Sapling has a very dated UI for its website, making it harder to use than necessary.
- Support for Multiple Languages: It only supports English.
- Integration with Outlook: Many users have complained about how hard it is to use Outlook integration (enable and disable).
Who Is Sapling Best For?
Sapling helps customer support and sales professionals, though it is hard to imagine how the content detection tools fit in with Sapling’s broader use cases. But just looking at its text generation detection, it offers a solid tool. Paid plans where one would get higher word count limits for detection are priced steeply, so organizations would need to use the full product to justify the costs.
Community Reviews and Ratings
Most users enjoy the whole suite of tools that Sampling offers, including AI grammar checks, AI writing, and content detection. The content scanning for AI content seems like a minor feature in their entire suite and should be considered a bonus for those wanting other AI tools.
Pricing
Completely free to use on their website with paid plans and more extended character limits starting at $25 per month.
5. Writer.com AI Content Detector
Writer.com is a complete AI writing and efficiency platform for business. It’s an all-in-one platform that helps improve your writing and spots AI-generated content (demo the AI Content Detector here). It’s a versatile tool that ensures content is grammatically correct and unique. It offers a tiny and free content scanner on the front end of its website. Otherwise, their content detection for AI written copy happens exclusively via its API. This means users looking for a quick scan won’t find much here.
Mainly for enterprises, Writer.com does everything. It can connect with your unique data and brand/voice guides to create and adjust the content to stay true to your business. The closest competitor would be Jasper in terms of the types of tools they are developing (outside of content scanning).
What We Like About Writer.com
- Grammatical Suggestions, Tone Recommendations, and Plagiarism Checker: Writer.com offers tools, including grammatical suggestions, tone analysis, and a robust plagiarism-checking feature.
- Free Character Check Up to 1,500 Characters: Writer.com allows you to check up to 1,500 characters for free, making it accessible for quick content checks. Their paid usage goes through their API, otherwise, even paid users must use the limited, free copy-and-paste scanner.
- Diverse AI Writing Tools and Features: The platform boasts various AI writing tools and features, catering to different content creation needs.
What Could Be Improved
- Expand Paid Detection: Its paid offering for content detection is only usable through the API. This means non-developers can’t use the system’s full force and must use the free tool they offer everyone.
Who Is Writer.com Best For?
Writer.com is ideal for professional writers and copywriting teams who want to ensure their content is well-written and free from AI-generated content. Its comprehensive features make it an excellent tool for those who wish to enhance their writing while ensuring its originality.
Community Reviews and Ratings
Writer.com doesn’t have many reviews on the sites we monitor. But, it offers enterprise-level AI tools for organizations. Small businesses are not likely to find this platform helpful, but larger ones with developers can utilize Writer for much more than only detecting content origins.
Pricing
Free, limited use of its front-end detector. Access to the API requires an Enterprise account with custom pricing done via a consultation.
6. Copyleaks
Copyleaks offers a simple-to-use AI-content detector on their website. It is designed to detect AI-generated academic content but is also suitable for other writing professionals. It also offers a Chrome Extension for detecting AI content on browsed pages.
Copyleaks’ major LMS partnerships bring this vital technology closer to academia to ensure the honesty and integrity of written assignments. They also have tools to help educators grade assignments fairly and objectively.
What We Like About Copyleaks
- Simple-to-Use Plagiarism and AI Detection: Copyleaks offers an easy-to-navigate interface for detecting plagiarism and AI-generated content.
- LMS Integrations: The platform seamlessly integrates with Learning Management Systems such as Canvas, Blackboard, and Moodle, enhancing its utility in educational settings.
- Chrome Extension for Real-Time Detection: Copyleaks provides a Google Chrome extension, enabling real-time plagiarism and AI content detection directly in the browser.
- Language Support: It supports content scanning in 30+ languages.
- Scans Source Code: Copyleaks can scan code to see if the code likely originated from another source or AI.
What Could Be Improved
- More Non-Enterprise Integrations: The enterprise plan connects with mainstream LMS solutions but relies on an API for standard plan integrations.
Who Is Copyleaks Best For?
Copyleaks is perfect for educators, students, and content creators who need a versatile tool for catching AI-generated content. Its ability to assess a wide array of AI-driven content makes it a valuable tool in academic and professional settings. It’s particularly beneficial for educators who need to ensure the originality of their students’ assignments and for students who want to verify the authenticity of their work.
Community Reviews and Ratings
Copyleaks is well-reviewed and loved by its users. Users enjoy that it can accurately do both AI and plagiarism detection. Their only consistent negative has been that sometimes scanning longer documents takes quite a bit of time.
Pricing
Plans start as low as $9.99 per month for AI detection. Plagiarism detection is only $10.99 per month. The monthly cost to get both is $16.99.
7. CrossPlag AI Content Detector
CrossPlag AI is a tool designed to detect AI-generated content with precision. It focuses on simplicity, making it a favorite among users who need quick and accurate results. Its intuitive interface and rapid detection make it a reliable tool for maintaining the integrity of your content. Moreover, its unique thermometer scale graphic visually represents AI-generated content, making it easy for users to understand the results.
Crossplag’s AI content detection is a new offering for their main plagiarism scanning tool. So, it does not have a lot of bells and whistles. It limits character length to 1,000 characters per free scan. Users must break up their larger documents into pieces to scan everything.
What We Like About CrossPlag
- Thermometer Scale for Confidence Levels: CrossPlag features a unique thermometer scale, visually scoring the confidence levels of its analysis, making it intuitive and user-friendly.
- Pricing for Individuals and Institutions: The platform offers flexible pricing options tailored for individual and institutional clients, accommodating a wide range of users.
- Data Protection with No Content Storage: CrossPlag prioritizes data protection by not storing any submitted content, ensuring high confidentiality and security for its users.
- Originality Scores: It also checks the originality of documents, which may, for some, be more helpful than seeing if AI likely wrote any content.
What Could Be Improved
- Better Reports: Though the thermometer is easy to understand, it only shows a high-level view. By highlighting particular content, users would better know the specific content written by AI.
- Language Support: It would be better for more users if it could scan more languages than only English.
- Better Integrations: It would be better if Crossplag could be integrated into more workflows to make it easy to use for non-technical users where they already spend their time working.
Who Is CrossPlag Best For?
CrossPlag AI is a simple tool for content creators and SEO professionals who need to ensure the originality of their content. It’s particularly beneficial for SEO professionals who must ensure their content’s originality to maintain their website’s SEO rankings. The people who stand to benefit from it the most are those who need plagiarism checking more instead.
Community Reviews and Ratings
Users enjoy Crossplag’s plagiarism and originality detectors. They also like to use the content detector since it doesn’t cost them the credits they’ve purchased for its main scanning tools. That said, Crossplag’s AI detection could become more advanced if they charged users for scanning. Its completely free policy toward AI scanning means the tool lags in development.
Pricing
AI Content detection is free to use (with an account), but plagiarism tools start at $9.99 monthly.
8. Content at Scale AI Text Detector
Content at Scale stands out as a unique tool, offering an AI detector as part of its AI writing platform. This comprehensive solution aims to equip users with deep insights into the genuineness of their content. More than just detecting AI-generated content, its Pro version immediately helps you rewrite it to sound more human-like, using its AI writing platform.
What We Like About Content at Scale
- Unique Human Content Score: Content at Scale offers a distinctive scoring system that assesses the human-like quality of content, providing a clear metric for content originality.
- Quick Verdict on Content Origin: The platform rapidly assesses the likely origin of the content, facilitating swift content evaluation.
- Immediate Pivot to Solutions: As an AI writing platform tailored to sound the most human, Content at Scale impressively rewrites AI-sounding content right away, a valuable feature for content teams.
What Could Be Improved
- AI Content Scan Only Option: Since Content at Scale comes with a whole AI writing suite of tools, it comes at a higher price tag. It’d be nice if there were an option to only use a paid version of the content scanner. Otherwise, users must pay for many more tools or only stick with their free AI content scanner.
Who Is Content at Scale Best For?
Content at Scale best suits businesses that blend human and AI content. Its unique scoring system provides detailed content analysis, making it a top choice for those eager to identify why content might be flagged as AI-generated. Its purpose is to detect AI-sounding content and then use the rest of its platform for rewriting. This focus makes it the most suitable tool for content writers and marketers among the tools on this list.
Community Reviews and Ratings
Users enjoy the AI-detection aspect of the tool. Their ideal user only needs to have the detector get in the ballpark with its accuracy because the whole system is made to rewrite specific sentences to make them better pass as human written. We don’t recommend using this tool to make unedited AI content pass other content detectors.
Pricing
Free usage on their website with extended usage with their AI Check + Generative AI plan starts at $49 per month.
9. AISEO
AISEO is a comprehensive platform that offers a suite of tools, one of which is its AI Content Rewriter. This tool scans text to see patterns indicative of AI-generated content. As it does this, it rewrites it to sound less like an AI wrote it.
You can use the rest of the platform to create AI-generated content with quick and practical workflows. AISEO builds every tool in its product suite for SEO. Obviously, creating quality and original content is crucial to that end. AISEO helps writers and content marketers ensure that their content is as fresh as needed.
What We Like About AISEO
- Scan and Rewrite Content from URL: Users can copy and paste their content into the detector or import it directly from a URL.
- SEO-Optimized Copy Generation: AISEO assists in creating optimized content for search engines, enhancing online visibility and reach.
- Easy to Use: Since it is less focused on showing its scan results, it speeds up the process by simply rewriting the troubling content.
- Multiple Supported Languages: A nice touch is that the content detector (as well as its AI writers) supports more than just English, which many others do not.
What Could Be Improved
- Bring Back Standalone Scanning: The tool used to provide a scan report but now rewrites the content straightaway. This is less helpful for those wanting to determine if an AI created the content. Instead, it is best for those who want a simple solution to fixing whatever AI content there may be.
Who Is AISEO Best For?
The AISEO Content Detection and Rewriting tool suits content marketers and editors who need to improve the originality of their content. It’s excellent for rewriting large volumes of content. Its advanced writing features make it a good choice for businesses that want to create quality content. It’s beneficial for SEO professionals who must ensure their content is unique to uphold their website’s SEO performance.
Community Reviews and Ratings
Community reviewers enjoy using an AI writing platform dedicated to better SEO content. Content detection gives many of them more peace of mind about the originality of their content through easy-to-use features.
Pricing
Limited free option with paid plans starting at $24 per month.
What are AI Content and Plagiarism Detectors Used For?
Low-quality AI content or plagiarized work can be a ticking time bomb for a business. If you don’t catch subpar content, it can trigger a host of problems:
- Immediate damage to reputation if work is found to be plagiarized
- Potential penalties from Google for low-quality content, as per changing E-E-A-T standards
- Overpayment to writers who may not have done the work they claimed to have done
- Possible future copyright issues
- Content that is merely average rather than exceptional
AI content detectors come to the rescue by helping to:
- Estimate if AI writing tools generated the content at hand
- Find copied or plagiarized work done by others
- Assess the percentage of original content of a piece
We all know that using AI carte blanche has inherent risks and a few new possibilities. A more thoughtful approach is to use AI alongside human writing practices. AI writing detectors can serve an essential piece in understanding the content before you—whether you wrote it yourself or are grading or editing the work of others.
Comparing Content Detectors
Content detection will become more important for businesses, schools, and individuals. Choosing the right tool can help you have the confidence to know, as best as possible, whether the content you are looking into was created with AI or by a human.
Feature Comparison
Technical features vary slightly by each tool. What you get will be determined based on your existing workflows and your needs for an AI content scanner. Here are the most important features these tools tend to have and how our top three choices compare.

Thanks so much for the list! Now the challenging part…how quickly will the list change considering how quickly ChatGPT/A.I. is evolving.
ChatGPT is only the tip of the “AI”ceberg. Lots of different LLMs are being developed and many for particular use cases (such as content analyzing and AI detection). I think some of these bigger AI detectors will do well for sometime. What I see as a bigger immediate problem is how Google analyzes content (and how it’s going to change over the next 18 months).
