Duplichecker is a free plagiarism detection service which has a set of other free tools including spell checker, visitor hit counter, keyword density checker, and many more. It is especially helpful for website owners, bloggers and writers who need to track their site positions and timely detect weak points.

According to the website, the Duplichecker plagiarism checker can also come in handy for educators and students. This online tool is totally free, however there is only one scan available for unregistered users.

Check Quality and Key Features

A user can check up to 1,000 characters at a time either by copy-and-pasting a text into the search box or by browsing .docx or text file. There is no need to download and install the program.

After each check is completed, Duplichecker provides a list of sources with text matches directly below the search box. Below each link, a user can see sentences with duplicated words in bold. To view what part of the checked text matches original source, it is necessary to click the Compare button. Then, a user will be redirected to another page where two text parts are provided side by side with similarities highlighted in red.

Results Delivery

Search results are given in the same window just in a few seconds after the search was launched. If the text is original the program doesn’t give any details – just a sign that there is no plagiarism detected. If some parts are plagiarized, the software will show duplicated sources and a user can click on it to see more details.


Duplichecker is another simple tool that performs checks quite efficiently. Its users can run scans simply by pasting texts into the search box on the website or by uploading a text document. Still, this checker doesn’t allow sharing report results or saving it for later editing.


Duplichecker is a popular anti-plagiarism tool, since it allows scanning medium-size texts and delivers results in no time. The program is used by Kansas State University and Academia.edu but those are not the only websites, which use Duplichecker successfully.
