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!

AI-Generated Reviews Spike After ChatGPT Launch

We analyzed 187,000 reviews about 15,231 companies at G2, a site for reviews about B2B software. Our AI detector examined the text of reviews to find how much content was likely generated by humans or AI.

Summary of Key Findings:

  1. More than 26% of reviews on G2 since the launch of ChatGPT are likely to be AI-generated. This represents an increase of 92.8% compared to before ChatGPT launched.
  2. High ratings of 4 to 5 were 1.7 times more likely to have AI-generated reviews.
  3. G2’s anonymous “Verified” reviews are 20% less likely to be AI-generated than those with names visible.
  4. After a peak of 34.6% in June 2023, the percentage of AI-generated reviews has fallen to around 19% in the most recent months. 

Study Method and Data:

  1. The text from 187,000 G2 reviews that were at least 100 words long were rated by Originality.AI’s AI detector as human or AI generated.
  2. We tracked the percentage of reviews rated as AI-generated over time.
  3. The product rating given along with each review was analyzed along with whether the review was written by a human or AI. The relationship between ratings and AI-generated text was analyzed. 

AI in G2 Reviews Study Findings

More than 26% of Reviews on G2, since the launch of ChatGPT, are suspected of being AI generated

AI in G2 Reviews Study Findings

Our AI detector examined the text of reviews to find how many of them were likely generated by humans or AI. We calculated what percent of reviews posted each month were AI-generated and tracked how that percentage changed over time. The amount of AI-generated reviews grew year after year as GPT-2 and GPT-3 were introduced. Then there was an immediate spike when ChatGPT became available on November 30, 2022, much like what we found in our study of Capterra, a similar software-review site. 

The first 11 months of 2002 averaged 15.2% of reviews being from AI, while December 2022 through September 2023 averaged 25.6%, an increase of 68%.

Note that the ~5% of reviews that were identified as AI generated before 2020 represent false positives that occur with AI detectors. Reference our accuracy study for more details - https://originality.ai/ai-content-detection-accuracy/

High Ratings of 4 to 5 Were 1.7 Times More Likely to Be AI-Generated

G2 High Product Rating Reviews 1.7 time More Likely To Be Ai Generated

The rate of AI-generated reviews differed by the rating given to the product. G2 ratings are on a scale of 0 to 5. We found that 26.93% of reviews with a rating of 4, 4.5, or 5 were written by AI, and that 15.98% of reviews with ratings of 0. 0.5, or 1 were AI-generated after the launch of ChatGPT. This difference made higher ratings 1.7 times more likely to have AI-generated reviews than lower ratings.

Anonymous, “Verified User” Reviews Were 20% Less Likely to Be AI-Generated

Along with the difference by product rating, there was also a difference in the percentage of reviews that appear to be AI-generated depending on how the author was identified. G2 allows reviews to be posted with the user’s name visible or anonymously as a “Verified User” with the author’s job field indicated, such as marketing or computer software. The verified reviews were less likely to be AI-generated than those with names attached, at 13.1% vs. 16.3% over the past six years, but the difference widened to 21.8% vs. 27.5% once ChatGPT launched. The anonymous reviews also had slightly lower ratings, with an average of 3.99 compared to 4.34 out of 5 for named reviewers. 

Recent Drop in AI-Generated Reviews at G2

2023 overall has seen a rapid increase in the share of reviews that are AI generated at G2, averaging 26% for the year so far with the high mark at 34.6% in June. However, beginning in August, the monthly averages hover around 19%. It remains to be seen if this lower average will become the norm. Possible explanations are that fewer AI-generated reviews are being submitted to the site or that the site has begun using AI-detection tools or other procedures to curb how many get published, which could mirror what we found in our study of another software-review site, TrustRadius.

Summary

Using AI to generate text for reviews presents challenges for everyone trying to use those reviews to make decisions, whether for personal or business uses. How do you feel about a review that was AI-generated? There could be times when it could be appropriate to use ChatGPT to improve readability, but is that what 26% of G2 reviewers have been doing since the generative AI became public? Do you want to feel like you’re in a Turing test every time you read a review? The findings in this study show how detecting AI can change how we use sites like G2 and rate their usefulness.

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.
