What Is AI Content and Why Do You Need AI Content Detection?
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.
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.
Exceptional accuracy: Originality.ai exhibits outstanding accuracy. It has 98% accuracy with 1.0.0 Lite (which permits light AI editing tools like Grammarly’s spelling suggestions). and 99%+ accuracy with Turbo (which has a 0 tolerance for AI).
Website scanning: It conveniently enables you to streamline your AI detection process with a website scan that analyzes your entire website for AI content with 1-click!
Plagiarism detection: You can simultaneously scan for plagiarism and AI with Originality.ai, which has a plagiarism checker that highlights potentially plagiarized content for further review.

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.
