Plagiarism Detector

Users of this online checker paste a passage, enter a web address or upload a file, and receive a breakdown of how much of the text is checked, unique and plagiarized.

How a check runs

Text is entered in a box on the page and submitted for checking. The site says the content is mapped into its internal network and compared with a database that it describes as millions of sites and the wider internet. Its algorithm is designed to ignore statistically common phrases, which the site says gives a more useful search for potential copying.

Reading the report

Beside the text box the report shows percentages for checked, unique and plagiarized material. Sentences that match existing online content appear below, each with its matched percentage, and every match points to the original source so the reader can compare the two texts. A fully original text returns a congratulations message instead. The site says results are 100 percent accurate, which is its own claim and not an independent measurement.

Free basic checking and the Pro version

The basic checker is free, and the site says a user can run as many searches as they like. A deep search adds further levels of matching and more detail in the results. The basic version accepts up to 1,000 words. The Pro version, which the site describes as the most trustworthy version of the tool, is built for longer work and takes up to 25,000 words, with a user-friendly interface and extra features.

Languages, web addresses and uploaded files

The checker works in several languages for users in other regions. Rather than pasting text, a user can enter the address of a web page, or upload a file. The firm says the tool supports multiple file formats.

Who uses it and why

The site names students, teachers and writers as its main users. Students can check an assignment before they hand it in. Teachers can check essays, papers and reports submitted to them. Web owners can check whether their own pages copy material from elsewhere, and can see whether someone has taken content from their site. The site says duplicated content can lower a page's standing in search and risk penalties from search engines, so it presents the tool as useful for search optimization as well as for academic work.

Consequences the site describes

The site sets out the consequences it associates with copying. In education these range from a zero on one assignment to suspension or expulsion. It also describes professional damage and legal exposure, including payment of damages for profit made from copied work and, in some cases, criminal prosecution. Its argument is that a check before submission is a low-cost way to avoid those outcomes.
