Copyleaks: Site Overview

Copyleaks has a 3.5-star rating based on 280 reviews, which means that users’ opinions are divided. In negative reviews, users mention a lack of accuracy and false detection of AI in human-written text. Copyleaks is ranked 13th among sites that help with content verification using artificial intelligence.

Copyleaks is broadly known as an accurate and intuitive checker for AI-generated content. Although the site offers a few other products, its AI Detector is best known. According to the independent study data published on Copyleaks, its checker is claimed to be the most accurate out there with the ability to detect 99.12% of human data and 95% of AI data.

Yet, the reputation of the service and Copyleaks reviews from customers demonstrate ambiguous opinions about the reliability and accuracy of the tool.

During our first-hand experience with Copyleaks, we were pleasantly surprised by its sleek interface and intuitiveness. The tool is easy to get started with and offers detailed reports. Yet, we’ve also detected certain lags and drawbacks.

Copyleaks: Our Experts’ Verdict

Copyleaks is one of the leaders in the market in terms of AI detection. The platform has been around for a while and offers a comprehensive AI detection solution that can help you ensure academic and professional integrity in your texts.

While studying the platform, we detected both the advantages and downsides of this tool. On the one hand, it claims accuracy, supports 30+ languages, and offers nice integration features. It also covers all AI models, which makes it stand out among many other similar tools. On the other hand, after scanning both human-written and AI-generated content using Copyleaks, we revealed that the checker can occasionally falsely detect AI, which means that you can’t rely on it blindly.

Among other things we didn’t like about this tool are a lack of efficient customer support, lack of accuracy, and lack of efficiency in its AI suggestion feature. Although it has been around for a while, Copyleaks still needs time to refine its algorithms to provide more accurate results. So, at the moment, we can’t recommend it to our readers.

Copyleaks Analysis: A Thorough Evaluation of the Platform’s Features

What is Copyleaks? In a nutshell, it’s a platform that offers cutting-edge solutions for academic integrity. The platform features three primary products:

- AI Detector
- Plagiarism Checker
- Writing Assistant

Yet, in this review, we’ll focus on Copyleaks’ AI Detector, in particular.

One thing we instantly found interesting while reviewing the platform’s AI tool is its diverse integration compatibility. First of all, the tool can be used as a browser extension. Additionally, there is API integration for enterprises and LMS integration for educational institutions.

Another thing that caught our attention is the support of 30+ languages. The checker can scan and detect AI content in English, Spanish, Portuguese, Italian, French, and many other languages, which makes it quite versatile for users across the world.

Now, let’s talk about the AI Detector’s functionality. How does Copyleaks work?

The tool pleasantly surprised us with its intuitiveness. When you land on the website, all you see is a large input box where you can paste your text and click “Scan.” Once the detection is complete, you will see a total score of AI content found in your text and highlighted parts of the text where AI was detected. Such an intuitive process is definitely a plus.

Copyleaks Support: Customer Help Quality

The first thing that disappointed us about Copyleaks was a lack of fast and intuitive ways to contact customer support. Being a technical tool that might be affected by occasional glitches and lags, we believe it’s supposed to have instant customer service available, preferably around the clock. Unfortunately, we didn’t find it on the platform.

There is an online chat with a virtual assistant that can help you with basic tasks like cancelation, booking a demo, etc. However, it doesn’t connect you with customer reps; it only takes contact details for future contact.

The only option that you have is to find a “Contact Us” button located in the site’s footer and submit a contact request using your email. After testing this feature, we received a response in around 10 hours, which is a rather long waiting time. It’s worth noting, though, that the site doesn’t promise a fast response. When you submit the contact form, they say that they will get back to you in 1-2 business days, making it a bad way to solve any urgent issues.

Despite a lack of efficient customer service, Copyleaks has a pretty extensive help center. In the help center, you can find detailed articles, troubleshooting guides, tutorials, and general answers to questions related to AI detection, security, billing, and other matters.

AI Model Coverage: What AI Tools Can Copyleaks Detect?

One thing that makes Copyleaks stand out from the crowd is that it offers complete AI model coverage. In simple words, its AI Detector goes far beyond detecting content produced by ChatGPT. Instead, it detects texts generated via other AI models, including Gemini, Claude, Jasper 3, and T5.

Furthermore, the platform promises that it will take up any new AI models as soon as they are released. And it also claims that it can easily detect paraphrased AI.

Apart from covering all AI models, Copyleaks also constantly evaluates the accuracy of its tool and trains it accordingly to enhance the outcomes. The evaluation is conducted based on the rate of correct and incorrect text identification cases and other metrics.

Nevertheless, despite such a holistic approach to its tool, our Copyleaks AI Detector review, as well as customer reviews, detect occasional lags and lack of accuracy in its scans.

Copyleaks Pricing: Trial, Pricing Plans, and Discounts

How much is Copyleaks? AI Detector is available for free right from the site’s home page. You can use it with a daily limit of 5 scans without creating an account or sign up for a free account and continue using the tool with the same limits but a more detailed report in your user dashboard.

If 5 scans per day is not enough for you, you can choose one of the two plans that contain AI detection:

- If you want to use AI + Plagiarism, the price ranges from $13.99/mo for annual billing or $16.99/mo for monthly billing.
- If you only want to use AI detection, the cost varies from $7.99/mo for annual billing or $9.99/mo for monthly billing.

Please note that these prices indicate that you will receive 1,200 or 100 monthly credits, depending on the chosen billing type. One credit equals 250 words, so it’s important to choose the plan according to your needs.

After you pick a plan, the platform gives you an opportunity to change or cancel it anytime. However, if you want to receive a refund, you need to cancel within the first 10 days of the billing cycle, without spending any credits.

Copyleaks Security

When using online plagiarism or AI detection software, many students get specifically concerned about safety. Apart from worrying about personal safety and privacy, many students are concerned about the possibility of their texts being stored or published elsewhere after they conduct an analysis, which can affect originality in the future.

Copyleaks answers such concerns firmly. The platform claims that its website and all tools have military-grade security. According to their policies, this includes using SOC 2 and SOC 3 certification and complying with GDPR guidelines. This means that when you use Copyleaks, your personal data, as well as the content you scan, remain safe.

While making this Copyleaks plagiarism checker review, we didn’t notice any violations of security or privacy. Furthermore, while analyzing Copyleaks’ reputation based on other users’ feedback, we also didn’t find any complaints about security, which allows us to state that using this service is fairly safe.

Copyleaks AI Insights

Of course, while testing the platform and its AI Detector, we couldn’t go past one of the latest features offered by Copyleaks – AI Insights. If earlier, AI Detector could only give you an overall AI score and highlight parts of the text that contain AI, this new feature offers real-time suggestions on how to improve your text and minimize AI.

In a nutshell, AI Insights tells you which AI-typical words and phrases appear frequently in your text and offers to avoid them.

To test the quality of the tool, we run analyses of both human-written and AI-generated text. In the human text, where the tool detected AI, we received a few AI suggestions and used them to improve the text. Unfortunately, the score didn’t change even by a tiny bit.

So, if you’re wondering – is Copyleaks trustworthy with its new feature? – we’d say it still needs to be polished.

Copyleaks Plagiarism Accuracy

Now that you know more about the work, features, pricing, and other aspects of Copyleaks, there is just one big question left to answer – how accurate is Copyleaks AI detector?

As was mentioned earlier, Copyleaks claims to be the most accurate detector on the market and supports this claim with third-party studies. Our experts tested the tool thoroughly using both human-written and AI-generated texts, and here’s what we can say.

Generally, Copyleaks does a good job of detecting AI in content. Yet, the tool is frequently affected by lags that make it detect human-written text as 50% or even 100% AI.

Multiple customer reviews also emphasize such false detections. Many users had the texts they wrote by hand detected by this tool as 100% AI. This makes us believe that Copyleaks still lacks accuracy in differentiating AI from human-written content.

Copyleaks Pros and Cons

All in all, while working on this Copyleaks AI content detector review, we found both advantages and downsides of the tool. While it is very intuitive to use and supports over 30 languages, the checker still seems to lack accuracy in its reports and features, which means that you can’t rely on it fully.

Pros:
  • ✅ Over 30 languages supported
  • ✅ Integrations for enterprises and educational facilities
  • ✅ Intuitive interface
Cons:
  • ❌ A lack of efficient customer support via phone or chat and a fairly long waiting time (1-2 business days) for support response
  • ❌ The new AI Insights feature doesn’t seem to work well for now
  • ❌ The checker occasionally lags and highlights human-written content as AI
  • ❌ In most cases, 5 daily scans aren’t enough to improve the quality of your texts, and you will have to purchase a paid plan
