A Quick Guide to Different Types of Plagiarism Checkers

Plagiarism checking tools have become an essential element of academia. Identifying instances of unoriginal content is one of the basic steps taken by scholars and writers to prove (or argue?) the authenticity of written text. Now that you’re armed with some of the best free instruments, we’ll focus on the different types of checkers, how they work, and the unique features of each.

Text Matching Plagiarism Checkers

Meet the most common plagiarism checker. The tool employs special algorithms that analyze the written texts. The tool detects near- or identical matches when the content already exists in their database.


The text plagiarism checker can easily detect verbatim or slightly paraphrased sections of text. It uses algorithms such as fingerprinting, matching, and other up-to-date techniques.

Pros & Cons

The text checker may struggle when it comes to ‘hunting’ for the so-called sophisticated forms of plagiarized texts. For instance, in the case of paraphrasing, the machine might get stuck. At the same time, blatant forms of plagiarism can be identified instantly.

Semantic Plagiarism Checkers

Semantic plagiarism text checker does more than just detect exact matches and focuses on the context and meaning of the text. The analysis of the semantic structures of sentences is performed by means of NLP (natural language processing) and machine learning algorithms.


As you work directly in the tool, you do the checks of meanings and context of sentences, word combinations, and words. Plus, the tool detects cases with different wording yet with the same underlying meaning.

Pros & Cons

When it comes to the pros, the checker is the best helper for detecting reworded/paraphrased texts. It identifies even the most subtle cases of plagiarism that text matching may miss. As for the cons of the checker, you may need more time and computational resources in contrast to the checkers with text matching principles.

File Comparison Plagiarism Checkers

Plagiarism checkers of this type do the comparison of entire files/docs rather than separate fragments of written text. In the uploaded works, the plagiarism checker seeks similarities, including issues like structure, formatting, and content, directly in the tool.


In texts uploaded directly in the tool, the plagiarism checker analyzes the overall similarity between several documents. The tool is used to detect similarities in images, formatting, etc.

Pros & Cons

The plagiarism tool does a great job of finding instances with entire documents repurposed or copied. In case the text was rearranged, the tool comes in handy. Still, the tool is not the most accurate helper to detect plagiarism within a document.

Online vs. Offline Plagiarism Checkers

Based on the accessibility of plagiarism detection tools, the checkers can be categorized into two forms – those that can be used offline and the ones that require a stable internet connection.

Online Plagiarism Checkers

Operating on web-based platforms, these instruments provide users with an opportunity to upload/paste texts right into the web browser. The plagiarism checkers from this category are easy to use, with some extra features like team editing or cloud storage available.

Offline Plagiarism Checkers

These are software applications that need to be installed on a computer or network. They are useful for organizations or individuals who require more control over the plagiarism detection process.

Users are required to install this plagiarism checker on a computer to have direct access to all the features. The tool is the right choice for individuals or companies that need more control over the process of plagiarism detection.

Picking the right type of plagiarism text scanner depends on a range of factors like your (or college) specific requirements, the accuracy level required by users, as well as the resources available. As you can see, every plagiarism checker has both – pros and cons. This means the most effective plagiarism checker always depends on the context in which it is going to be employed.
