We looked at 26,000 Amazon product reviews to answer the question: ‘Did an AI write that review?’

Summary of Key Findings

  • 400% increase in AI generated review since the launch of Chat GPT.
  • With the advent of Chat GPT in November 2022, there was an explosion of the use of AI-generated content in product reviews by approximately 400%
  • Extreme reviews are 1.3 times more likely to be AI generated.
  • Reviews with strong bias are more likely to be written with AI assistance
  • Verified reviews are 1.4 times less likely to have AI Content
  • The good news is that AI generated reviews are more likely to be from unverified sources and regarded as unhelpful. The bad news is that might not be the case for much longer.
  • Users Intuitively Find AI Generated Reviews Less Helpful
  • There is a small but significant negative correlation between the helpful scores of a review and its probably AI Content.

Methodology

Over 26,000 Amazon product reviews were randomly selected to generate the source dataset. These records were cleaned using standard processes, which included removing all customer-sensitive and identifying information. A statistically representative subset of 2,000 records was processed with Originality.AI’s AI Detection API. The most accurate AI detector to analyze text data for the likelihood of AI Content and returns a probability score of 0 to 1.

Findings

Since Chat GPT launched AI generated reviews increased by 400%

AI-enhanced text generators pre-existed Chat GPT. GPT-3 was released in June 2020, quickly followed by the writing aid tools that leveraged it. However, since the launch of Chat GPT, text generators progressed from limited, niche applications to more widespread usage. Trend analysis of the dataset indicates that on average, the number of product reviews with 50% or more AI Content has grown since the average annual value of 0.02 in 2022. As at publishing date, this value has increased by approximately 400%. There are no signs of slowing down.

Ai Usage in Amazon Reviews

Extreme Reviews are 1.3x More Likely to be AI Generated

There are two kinds of reviews: The extreme 1-ers and 5-ers who either love or hate a product passionately and want everyone to know this. Or the Chill Trio – 2s, 3s, and 4s. As it turns out, they’re Chill in more ways than one as these reviews appear less likely to rely on AI text generators. According to our findings, AI content is approximately 1.3 times more likely to be detected in Extreme reviews than Moderate reviews.

Visual Analysis of Rating Severity vs ai Content

Verified Reviewers are 1.4x Less Likely to be AI Generated

Visual Analysis of is Verified vs ai Content

There are some bright spots. Analysis shows that Verified reviewers are roughly 1.4 times less likely to be AI generated than non-verified reviewers. Amazon.com values the integrity of the review process and goes to great lengths to safeguard it. However, not all ecommerce websites have Amazon’s resources.

Users Intuitively Find AI Generated Reviews Less Helpful

Standardized Helpfulness Count Vs Ai Content Probability

Another optimistic discovery came from analyzing the helpfulness score of a review (eg. ‘20 people found this review helpful’) that is used to rank reviews. It appears that people are more likely to be instinctively biased against AI content. Or to be precise, there is -0.06 correlation on average between standardized helpfulness and likelihood of AI Content. And yes, that’s supposed to be the good news. The bad news is that this figure doesn’t factor how potential bot-voting skews that statistic or if reviews that have been around longer get more votes.

Summary: Amazon Ai Generated Reviews

Further analysis is still being done. It will take some time to build a large enough dataset to answer all the burning questions with statistical confidence. But this is enough to get us thinking. There’s nothing wrong with the use of AI Content, especially in a free public service like sharing your genuine opinion on a product. But that’s assuming that all those reviews are free and genuine, and not… 😷motivated by vested interests, competition, and paid reviews 😷. 

Finally, ask yourself: would it make a difference to your purchasing decisions if you knew that the review that persuaded you to click on ‘Add to Cart’ came from a heartfelt human anecdote… or from the articulate logic of a well-trained machine?

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.

In The Press

Originality.ai has been featured for its accurate ability to detect GPT-3, Chat GPT and GPT-4 generated content. See some of the coverage below…

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?
