Paraphraser.io offers quick and efficient plagiarism detection. However, it is not as accurate, especially where complex types of plagiarism, like patchwork plagiarism, are concerned. 

Although Paraphraser.io offers other tools, such as an article rewriter and text summarizer, for the purposes of this review, we focused on testing the plagiarism checker.

The platform is free to use up to 1,000 words.

Paraphraser.io is a quick and efficient plagiarism checker that provides an easy way to check for plagiarism without payment. 

This makes it an enticing option for many who are looking for a budget-friendly plagiarism checker for content such as essays or articles. 

Who Is Paraphraser.io Best For?

Paraphraser.io is mainly designed for students, SEO, and content writing professionals who need a fast way to check for broad plagiarism. 

As you’ll see in our Paraphraser.io review, the tool does detect copy-paste plagiarism. 

However, beyond clear, direct copying and pasting, it detected a lower overall efficacy in detecting patchwork plagiarism. 

The Test

In order to make the test as fair as possible, we tested both tools’ plagiarism detection capabilities using both verbatim copy and pasted text samples as well as samples of patchwork plagiarism in text. 

Part 1: Plagiarism Test With Published Blogs

Step 1: We started with two blog posts from the Originality.ai blog.

Step 2: We then pasted the content directly into the Originality.ai plagiarism checker and the Paraphrase.io plagiarism checker to see if it was able to detect direct plagiarism.

We selected text samples from these published posts on our blog:

  1. 7 Benefits of Using a Sentence Grammar Checker
  2. What Does a Marketing Agency Do?

Part: 2 Plagiarism Test With Patchwork Plagiarism Samples

Step 3: As many examples of plagiarism are far more involved and subtle than just copying and pasting text directly, we also wanted to check for patchwork plagiarism, which is another example of plagiarism. We chose two samples of text for this exercise. 

Step 4: We then ran both samples through Paraphraser.io and the Originality.ai plagiarism checker to compare the results.
