That’s where an AI Content Detector comes to the rescue. AI detection tools act as the guardians of online content, ensuring that the content you publish is high-quality, SEO-friendly, and informative.
This article reviews the best AI content detection tools and how they can elevate your content game to the next level.
Note: At Originality.ai, our machine learning engineers continually work to improve our tools. Some of the AI detectors in this list were tested on previous models. For details on the latest models, check out our AI detector accuracy review.
AI Content is a type of artificial intelligence (AI) software-generated content. AI systems train to create articles using natural language processing and machine learning algorithms.
The International AI industry has grown significantly, especially in the scope of content creation.
AI content is rapidly increasing in Google, as it enables businesses to produce high volumes of AI-generated content in a fraction of the time it takes humans to write the same articles from scratch.
However, although AI creates content quickly, its quality is often inconsistent in writing style, informational depth, and analysis. Google’s helpful content update in August 2022 revealed that the search engine giant would penalize any content that lacks depth or expertise.
So, as a webmaster, you must prioritize creating people-first content that’s high-quality and informative to reduce the risk of being penalized by Google.
Looking for more information about AI content detection? Read the Originality.ai AI Content Detector Accuracy Review.
We have comprehensively tested and compared several AI Content Detection Tools. Here are our top picks based on their features and pricing.
The Originality.ai AI detector tops our list as the best AI content detection tool. It demonstrates exceptional accuracy across a meta-analysis of 8 third-party studies and offers comprehensive features, including AI and plagiarism detection.

Are you wondering, ‘can Google detect AI content?” The answer is both yes and no. Google can detect overly simplified AI content. However, if your AI-generated content is optimized adequately with a human touch, the chance of detection is less.
Google does not directly say that it will penalize AI content. Instead, it emphasizes penalizing low-quality content lacking the depth of research and expertise on the subject matter.
Google bots use advanced algorithms to “read” your website’s content and identify any AI-generated (or human-generated) material that doesn’t meet the standards of quality set by Google. If detected, this type of content will be flagged by Google as low quality and could negatively affect your website’s ranking in search results.
As a webmaster, you can rely on AI detection scoring to discover the likelihood of AI presence in your text to highlight it for further review, so you can publish content confidently.
We’ve reviewed over 30 highly reputed AI text detection tools in this post, and Originality.ai has topped them all as the best AI detection platform based on features, pricing, and convenience of use.
No, that’s one of the benefits, only fill out the areas which you think will be relevant to the prompts you require.
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.

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.
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.
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.
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.
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.
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.
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.
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.
