Buyers Guide

Last Updated: March 16, 2023

Plagiarism refers to copying someone else’s content (including ideas, words, or work) and presenting them as your own without acknowledging the source.

If you’re a writer or you author anything such as blogs or reports, nothing can damage your reputation more than an accusation of plagiarism. Possible repercussions depend on your role (student, experienced academic, or professional) and could lead to poor grades, suspension from the university, copyright infringement, and ruined reputation.

This buyers guide will help you choose an online solution for detecting plagiarized content, done unintentionally or otherwise.

In this guide, we’ll cover:

What is plagiarism checker software?

Plagiarism checker software is a tool that comes with algorithm-based text detection capabilities to recognize plagiarised content. The tool scans web pages and databases (free as well as paid) to identify the usage of the same terms, quotes, sentences, paragraphs, and titles along with similarities in wording and paraphrasing.

Additionally, the software offers features such as writing suggestions, citation generator, and indexing. Writers, bloggers, students, teachers, and professionals/businesses working on projects such as content creation, storytelling, and marketing make up the primary users of this type of software.

What type of buyer are you?

Before purchasing a plagiarism checker tool, you should assess what kind of buyer you are. The majority of use cases fall into one of these categories:

Freelancers: If you’re freelancing, it is important to get recognized each time your work is referenced. Also, it is important to be alerted when you have unintentionally copied someone else’s work or missed a citation in your content. Plagiarism software enables you to stay on top of these tasks through comprehensive reporting, and thus, ensuring originality and honesty in your work.

Academic institutions: Plagiarism software enables educational institutions with in-depth analysis of students’ works. Some products allow evaluators to grade assignments as well. Paraphrasing and source citing suggestions greatly enhance the quality of students’ work, thus enhancing their productivity.

Business: If you are a business owner, ensuring the authenticity of your content should be one of the major reasons to adopt plagiarism checker software. Duplicate content not only impacts your reputation but SEO ranking as well. This becomes all the more important when you outsource your content creation.

Benefits of plagiarism checker software

Here are the biggest benefits you will see from using online plagiarism checker software in your organization:

Multiple content and language support: The tool allows running plagiarism checks on multiple documents simultaneously. This avoids repeating the efforts on checking the originality of several iterations for a given (or similar) topic. A potential use case could be in academic institutions where teachers can check for plagiarised content in assignments submitted by the whole class. The content can also be checked for plagiarism in multiple languages.

Regulatory compliance and ethical limits: Plagiarism is not legal and if your content violates copyright laws, you can face copyright infringement charges with heavy penalties. The plagiarism checker software analyses the content and presents the analysis based on different metrics. You can see these results in the form of an extensive similarity report that highlights common words (which can be replaced with synonyms) as well as other suggestions that fit-in your work.

Key considerations

With so many options and features to choose from, selecting the right plagiarism detection tool can quickly become overwhelming. To narrow the search list, here are some key factors to keep in mind when you evaluate different products:

Data protection: When searching for plagiarism detection software, check the product’s data sharing and retention policy. Your documents, which can be confidential, should not be made public or passed on to third parties without your permission. Also, deleted files should get completely erased from the software’s backend and not retained for any purpose. Prefer a solution that uses data and document encryption techniques to ensure safe upload/download/transfer.

Integration: Some plagiarism checker software offer product extensions that can be integrated with Microsoft Word, Apache OpenOffice, Google Docs, Google Chrome, etc. It enables users to check plagiarism and incorporate suggested edits easily while working on the document. Users can simply copy-paste the content into the extension’s workspace and identify plagiarised text.

Whitelisting: Some plagiarism detection tools allow users to define certain sources (such as specific websites or databases) that can be excluded from the checklist. For example, if you are a teacher and have asked your students to refer to certain online journals for an assignment, you can whitelist those sources so the software will not check for plagiarised content across those authorized sources. Similarly, if a business wants to exclude certain industry-specific terms/phrases during plagiarism scans, they can do so by whitelisting those terms.
