Introduction

Our text compare tool is a fantastic, lightweight tool that provides plagiarism checks between two documents. Whether you are a student, blogger or publisher, this tool offers a great solution to detect and compare similarities between any two pieces of text. In this article, I will discuss the different ways to use the tool, the primary features of the tool and who this tool is for. There is an FAQ at the bottom if you run into any issues when trying to use the tool.

What makes Originality.ai’s text comparison tool stand out?

Keyword density helper – This tool comes with a built-in keyword density helper in some ways similar to the likes of SurferSEO or MarketMuse the difference being, ours is free! This feature shows the user the frequency of single or two word keywords in a document, meaning you can easily compare an article you have written against a competitor to see the major differences in keyword densities. This is especially useful for SEO’s who are looking to optimize their blog content for search engines and improve the blog’s visibility.

Ways to compare

File compare – Text comparison between files is a breeze with our tool. Simply select the files you would like to compare, hit “Upload” and our tool will automatically insert the content into the text area, then simply hit “Compare” and let our tool show you where the differences in the text are. By uploading a file, you can still check the keyword density in your content.

URL compare

Comparing text between URLs is effortless with our tool. Simply paste the URL you would like to get the content from (in our example we use a fantastic blog post by Sherice Jacob found here) hit “Submit URL” and our tool will automatically retrieve the contents of the page and paste it into the text area, then simply click “Compare” and let our tool highlight the difference between the URLs. This feature is especially useful for checking keyword density between pages!

Simple text compare

You can also easily compare text by copying and pasting it into each field, as demonstrated below.

When you think about the concept of generative AI, your mind likely pictures tools like Claude, ChatGPT, or Google Gemini, all of which are well-known for their content-generation features.

Each of these tools uses generative AI by taking prompts and can turn them into text-based responses.

However, generative AI has also led to other popular uses through AI humanizers and AI rewriters.

Here, we’ll take you through AI humanizers vs. AI rewriters, establishing key differences and whether or not they are detectable by AI content detectors.

Short on Time? Here Are the Key Takeaways

  • AI humanizers and AI rewriters both use large language models similar to popular generative AI tools like Claude, ChatGPT, and Gemini.
  • Humanizers typically attempt to make AI content sound more casual and engaging (and human), and rewriters tend to focus on tidying up sentence structure.
  • Both humanizer and rewriter content are detectable by the Originality.ai AI detector.

What Are AI Humanizers and Rewriters?

First off, let’s start by looking at each type of tool in more detail, outlining their differences and why they have become so popular.

AI Humanizers

Firstly, let’s focus on AI humanizers. By definition, AI humanizers attempt to make your AI content sound more natural and engaging. 

Generative AI tools use large language models and natural language processors to produce results, so the output can tend to sound rather formulaic and, therefore, quite stale.

In many instances, that type of content needs to be amended to be more insightful and engaging.

Rather than spending time doing this manually, many humanizers claim they can do this for you, using the very tools and processes that cause the formulaic content in the first place.

As you can imagine, this process is not particularly effective, which we will touch on later in this piece.

AI Rewriters

AI rewriters, on the other hand, generally market themselves as tools that help structure content, tidy up grammar, and rewrite it in a better format.

AI rewriters have a wider use case than AI humanizers, especially for those who are looking to refine the tone of content, such as making it more conversational or formal.

However, these tools also come with concerns and drawbacks, such as producing disengaging content output.

Can They Get Detected by AI Content Detectors?

With all that in mind, it’s also important to review whether or not the content generated by AI humanizers and AI rewriters is detectable. 

For the test, we first generated an article in ChatGPT that was 100% AI-generated. 

Below is the prompt we used:

Here is the Originality.ai AI Detection Score for the ChatGPT content — 100% Confidence that it is Likely AI.

AI Humanizers

For our AI humanizer test, we will use Humbot, one of the most popular and heavily marketed AI humanizer tools.

Now, we can take that text initially generated by ChatGPT and run it through Humbot to get our “humanized” version.

Then, we can run it through our AI content detector.

The Originality.ai AI Detector identified the “humanized” text as Likely AI with 100% Confidence.

A quick look at the actual content highlights the main issue with many of these tools:

“Humanized” content sample

The text is riddled with errors, random capital letters, incorrect grammar, and so on. 

This poor grammar is a method that Humbot (and many other AI humanizer tools) use to try and trick users so that it can bypass detection. However, in reality, it just turns content into a jumble of words that no longer makes a clear sentence.

You can read our full review of Humbot AI here.

AI Rewriters

So, what about AI rewriters? Are they any more effective?

Let’s take our YouTube example again and run the ChatGPT-generated version through the Ahrefs paragraph rewriter. 

Now we can check that version in Originality.ai.

The Originality.ai AI Detector identified the text with 100% Confidence as Likely AI.

As you can see from the results, while Ahrefs' output was much more coherent than Humbot AI, Originality.ai managed to detect the content with 100% Confidence that it was Likely AI.

Final Thoughts

In summary, while there are certainly some differences between AI humanizers and AI rewriters, there is one very common feature — both AI humanizers and AI rewriting outputs are still detectable as AI content.

Similar to generative AI tools, AI humanizers and rewriters can be useful tools in some use cases but certainly can’t be treated as writing replacements.

For the best results using such tools, we recommend using them sparingly and as support rather than as a replacement.

Frequently Asked Questions About AI Humanizers vs. AI Rewriters

Are AI Humanizers and Rewriters useful for SEO?

Neither AI humanizers nor rewriters are good for SEO as the content they both produce could get flagged as AI spam by Google, leading to potentially even bigger problems and Google penalties.

Do AI Humanizers and Rewriters require human editing?

As with all AI-generated content, including that of ChatGPT, the content output always requires detailed editing to ensure it matches your brand tone of voice and provides true value to your audience.

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.

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?

We have support for the file extensions .pdf, .docx, .odt, .doc and .txt. You can also enter your text or copy and paste text to compare.

Will My Data Be Shared?

There is never any data saved by the tool, when you hit “Upload” we are just scanning the text and pasting it into our text area so with our text compare tool, no data ever enters our servers.
