Its website claims that the platform is used in over 100 countries to help individuals improve their writing. 

The Test

We focused entirely on the accuracy of PaperRater’s online plagiarism checker in order to make a direct comparison to Originality.ai’s Plagiarism Checker.

We divided the test into two parts: 

Part 1: Plagiarism Test With Published Blogs

Step 1: We first took two blog posts from the Originality.ai blog.

Step 2: Next, we pasted the blog content directly into the Originality.ai Plagiarism Checker and into the PaperRater plagiarism checker.

We chose text samples directly from the Originality.ai 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: For the second part of the test, we chose examples of patchwork plagiarism. Patchwork plagiarism is a more challenging example of plagiarism and can be difficult for even modern plagiarism detectors to uncover. 

Step 4: We then ran both samples through PaperRater and the Originality.ai Plagiarism Checker to compare results. 

The Results

Plagiarism Test With Published Blogs

Blog Sample 1: 7 Benefits of Using a Sentence Grammar Checker 

Originality.ai Plagiarism Checker: 100% Match

PaperRater: 0% Match (100% Original)

Blog Sample 2: What Does a Marketing Agency Do?

Originality.ai Plagiarism Checker: 100% Match

 PaperRater: 0% Match (100% Original)

Patchwork Plagiarism Test

Patchwork Plagiarism Sample 1

Originality.ai Plagiarism Checker: 77% Match


PaperRater:
3% Match (97% Original)

Patchwork Plagiarism Sample 2

Originality.ai Plagiarism Checker: 62% Match

PaperRater: 30% Match (70% Original)

The Findings

PaperRater was unable to find any evidence of plagiarism when it was tested with two different examples of text copied and pasted directly from the Originality.ai Blog. 

When tested with the patchwork plagiarism examples, it still delivered inconsistent results, with 3% plagiarism detected and 30% respectively. Where the tool was able to find instances of potential plagiarism, it highlighted the part(s) of the passage as well as showed the potential source.

In contrast, Originality.ai identified both of the blog samples with a 100% Match. Then, when it came to the more challenging patchwork samples, Originality.ai found a 77% and 62% Match with Patchwork Samples 1 and 2, respectively.

Frequently Asked Questions

Do I have to fill out the entire form?

No, that’s one of the benefits, only fill out the areas which you think will be relevant to the prompts you require.

Why is the English so poor for some prompts?

When making the tool we had to make each prompt as general as possible to be able to include every kind of input. Not to worry though ChatGPT is smart and will still understand the prompt.

Originality.ai did a fantastic job on all three prompts, precisely detecting them as AI-written. Additionally, after I checked with actual human-written textual content, it did determine it as 100% human-generated, which is important.

Frequently Asked Questions

Why is it important to check for plagiarism?

Tools for conducting a plagiarism check between two documents online are important as it helps to ensure the originality and authenticity of written work. Plagiarism undermines the value of professional and educational institutions, as well as the integrity of the authors who write articles. By checking for plagiarism, you can ensure the work that you produce is original or properly attributed to the original author. This helps prevent the distribution of copied and misrepresented information.

What is Text Comparison?

Text comparison is the process of taking two or more pieces of text and comparing them to see if there are any similarities, differences and/or plagiarism. The objective of a text comparison is to see if one of the texts has been copied or paraphrased from another text. This text compare tool for plagiarism check between two documents has been built to help you streamline that process by finding the discrepancies with ease.

How do Text Comparison Tools Work?

Text comparison tools work by analyzing and comparing the contents of two or more text documents to find similarities and differences between them. This is typically done by breaking the texts down into smaller units such as sentences or phrases, and then calculating a similarity score based on the number of identical or nearly identical units. The comparison may be based on the exact wording of the text, or it may take into account synonyms and other variations in language. The results of the comparison are usually presented in the form of a report or visual representation, highlighting the similarities and differences between the texts.

String comparison is a fundamental operation in text comparison tools that involves comparing two sequences of characters to determine if they are identical or not. This comparison can be done at the character level or at a higher level, such as the word or sentence level.

The most basic form of string comparison is the equality test, where the two strings are compared character by character and a Boolean result indicating whether they are equal or not is returned. More sophisticated string comparison algorithms use heuristics and statistical models to determine the similarity between two strings, even if they are not exactly the same. These algorithms often use techniques such as edit distance, which measures the minimum number of operations (such as insertions, deletions, and substitutions) required to transform one string into another.

Another common technique for string comparison is n-gram analysis, where the strings are divided into overlapping sequences of characters (n-grams) and the frequency of each n-gram is compared between the two strings. This allows for a more nuanced comparison that takes into account partial similarities, rather than just exact matches.

String comparison is a crucial component of text comparison tools, as it forms the basis for determining the similarities and differences between texts. The results of the string comparison can then be used to generate a report or visual representation of the similarities and differences between the texts.

What is Syntax Highlighting?

Syntax highlighting is a feature of text editors and integrated development environments (IDEs) that helps to visually distinguish different elements of a code or markup language. It does this by coloring different elements of the code, such as keywords, variables, functions, and operators, based on a predefined set of rules.

The purpose of syntax highlighting is to make the code easier to read and understand, by drawing attention to the different elements and their structure. For example, keywords may be colored in a different hue to emphasize their importance, while comments or strings may be colored differently to distinguish them from the code itself. This helps to make the code more readable, reducing the cognitive load of the reader and making it easier to identify potential syntax errors.

How Can I Conduct a Plagiarism Check between Two Documents Online?

With our tool it’s easy, just enter or upload some text, click on the button “Compare text” and the tool will automatically display the diff between the two texts.

What Are the Benefits of Using a Text Compare Tool?

Using text comparison tools is much easier, more efficient, and more reliable than proofreading a piece of text by hand. Eliminate the risk of human error by using a tool to detect and display the text difference within seconds.

What Files Can You Inspect with This Text Compare Tool?

Will My Data Be Shared?
