Company: Copyscape

Copyscape was launched in 2004 as a response to the problem of content theft on the internet. It allows users to check if their content has been plagiarized and where it has been published without their permission. The service is provided by Indigo Stream Technologies Ltd, headquartered in Israel.

Copyscape is quick, efficient, and reliable, making it a great tool for anyone who needs to check for plagiarism. Compared to other checkers like ProWritingAid and Scribbr, Copyscape can check text within a few seconds.

For this example, Copyscape Premium was able to check an article around 2,000 words in less than two seconds. My internet speed at the time was 43.72 mbps. This makes Copyscape truly one of the fastest plagiarism checkers in the market. The results for text similarity were accurate as well.

I also tested the free Copyscape tool to check the uniqueness of a blog article of less than 1,000 words. Again, it only took around two seconds to generate the results. Interestingly, the checker only detected similarity in the Disclaimer and Contact Us sections, which meant the article itself is most likely unique.

With Copyscape, your content is your property. When you submit your content to Copyscape, you can easily find out if anyone had plagiarized it (or if you had plagiarized theirs). If so, Copyscape will help you take the necessary steps to get the content removed and help protect your intellectual property rights.

Ease of Use

Though the interface looks quite dated, Copyscape’s interface is straightforward to use. It has a bit of a learning curve for a beginner, but it is still manageable because of the user-friendly interface, and the steps are easy to follow.

Here, I will show you how Premium Search works. Simply enter your text in the text box, and Copyscape will return the list of pages that could be similar. These include precise duplicates, incomplete copies, and copies that differ significantly from the original.

Based on the sample content below, after I clicked the “Premium Search” button, it showed that there were no similar pages or articles detected, making the text safe for plagiarism.

On the other hand, this is what would happen if Copyscape detects plagiarism. Here, it’s easy to see there are 28 results found which are similar to the content. Each result contains a link and a button to compare the text.

Upon clicking “Compare Text,” it redirects the user to the corresponding website, highlighting the matching text. The page also shows the number of words that matched along with the percentage, and the results were accurate to the text.

It would be easy to use the software daily. However, since Copyscape Premium uses a credits-based payment structure that depends on the number of words you check, some users may find it cumbersome to reload the account every time it runs out.

The free checker is also easy to use, though very limited compared to the paid options. You can only enter the URL of the content you wish to check, so unlike other plagiarism checkers, you can’t directly input your own text without shelling out some money.

I didn’t find any issues when it comes to speed or uploads. Unlike other plagiarism checkers like ProWritingAid or Quetext which considerably take more time, Copyscape returns results almost instantly. Batch searches understandably take longer, but the software will also display an estimate for its duration.

You can also integrate Copyscape Premium with your content management system to make checking for plagiarism easier, although you might need some developer knowledge to use the API. Copyscape integrates with popular platforms, including WordPress, Blogger, Drupal, Joomla!, and Medium. The platform also integrates with publishing tools such as Microsoft Word, Google Docs, and Adobe InDesign.

Customer Support

Copyscape offers ticket submission through its online form. You may also email the support team directly, and they will respond to you within 24 hours. Many resources are also available on their website, including an FAQ section, user guide, case studies, tips & tricks, and a blog. With this, it is easy to find answers to common questions.

I can easily access Copyscape’s “Help” section by hovering on the dashboard. There are three options for customer support: FAQs, Forum, and Contact Us.

For FAQs, Copyscape has a search bar to enter keywords or questions. The search result will show the related topics and articles for the issue at hand. Also, there is an option to post the question on the Copyscape Forum, where the community can try to answer my queries.

The last resort would be to contact Copyscape support through the “Contact Us” form, after which their team will get back within 24 hours.

Upon clicking the “Contact Us” button, I can place my inquiries in a textbox. I can also include the URL of the page in question. Additionally, I was prompted to enter my email address and solve a simple equation to prove that I wasn’t a spammer.

After submitting, a popup window stated, “Your message has been sent. A customer support representative will reply to you as soon as possible.”

Unfortunately, phone support and live online chat are unavailable, so it would be hard to get a hold of a live agent quickly. Video tutorials are also lacking, although I find the software straightforward enough to use that they may not be necessary for most users.

Text Similarity Detection

Like other plagiarism checkers, Copyscape lists online sources that are similar to your content. However, it does not highlight outright which parts of the text are similar, and you have to click on the links to check. It also doesn’t report
how much of the content is not unique in terms of percentages, which is quite a basic feature in competitors.

Multiple File Format Support

Copyscape supports uploading files in PDF, DOC, DOCX, RTF, and TXT, compared to most software that can only check for plagiarism from pasted text.

Copyscape is an excellent tool that can save you time and headaches against plagiarism, especially for writers with bulk content. The software is valuable because it not only helps to ensure that your content is unique, but it also allows you to check lots of text or pages easily and take appropriate action when you find your content has been published without your permission.

With its features, we can say that Copyscape is worth the investment whether you are a student, blogger, freelance writer, or business owner. That said, Copyscape is specialized for plagiarism checking only, so if you need more tools to help you with writing, another software may better suit your needs.
