Describing 5 amazing tools which help to check plagiarism for free

What is a plagiarism checking tool?

The advent of the World Wide Web has made information freely available to all. With so much content flowing continuously across websites, it is quite easy for people to steal other people’s work and pass them off as their own.

This act of copying content from its original source is called plagiarism.

A plagiarism checking tool is a web application that helps in identifying instances of copied content. These tools are extensively used in the content marketing and academic industries since plagiarism is a big no-no in such spheres. It ensures that the text you’re writing is free from any sort of copied content.

In this age of internet, it is highly advised to use a plagiarism detection software in order to avoid copyright issues. They also ensure that your text is free of duplicate content before you publish.

How does an online plagiarism checker work?

The modern day plagiarism checkers use artificial intelligence and automated algorithms to analyze your content and throw results if they find similar content on the web using Google and other search engines.

The three main ways these online tools work are –

1. By copy pasting your data into their tool – It is the simplest method used by many tools that allow to check plagiarism for free. In this method, there is usually a cap on the number of words that you can analyze at a time (~1000 words).

2. By providing content URL – Many tools allow you to submit the URL of your page that you want it to compare. The tool analyzes the entire content of the webpage document and provides you with the result.

3. By uploading the content document – The third method involves uploading the content file into the tool post which it analyzes the content. This method is seen primarily in premium versions, while some free plagiarism checkers may also allow you to upload.

Most of the popular tools available on the web provide all three types of inputs, with content copying and pasting being the most widely offered free method.
