7 Best AI Content Detector Tools [Free and Paid]

How Does AI Content Impact Your SEO Ratings?

The one Google algorithm you should keep in mind is the SEO of your content which is determined by the right keywords, citation listings, meta tags, readability, domain links, accessibility etc. 

Google, in its recent report named “Google Search's guidance about AI-generated content”, claims that it prefers original content which is high quality and demonstrates the following features - experience, expertise, trustworthiness, and authoritativeness. 

While Google remained unchanged in its policy about how the quality of the content is more important than how the content is produced, the company was also transparent that using automation or AI to generate content to manipulate SEO ranking in the search results is a direct violation of their spam policies. 

In a nutshell, Google rewards the production of original, high-quality content and using AI responsibly is not against its guidelines. However, this does not take away the anxiety of business owners about their SEO rankings. So, here is a comprehensive list of AI tools to help you detect any AI-generated content that might pull down your SEO rankings.

Find out the best features of these AI Content Detector tools and determine how they work,  what are their quirks, and if they suit your needs.

1. Sapling

Sapling’s ongoing project is to assist business communications with the help of AI. Saopling aims to improve communication between business teams and their clients and make it more efficient and fruitful. Sapling AI detector uses a machine learning system to detect AI-generated content. Most AI-generated content comes from models such as ChatGPT or GPT-3.5. So, when presented with the content, AI detectors calculate the probability of each word being AI-generated. 

Key Features:

• Sapling has more than 97% accuracy in detecting AI-generated content, while below 3% of the results might be false positives. So, it is advised that you check with other AI detectors as well. 
• The Sapling free version allows you to check for 2000 characters which equals 400 to 500 words simultaneously. To check for more extended text versions, you can use the Pro and Enterprise Sapling subscriptions to check 8000 characters at a time. 
• Language models are increasingly becoming advanced daily with OpenAI GPT-4 or Anthropic Claude entering the market. But they usually use similar datasets and machine learning systems on which all language models are generally trained. So, Sapling AI should perform equally well with the advanced language models. 
• Sapling AI updates its detector regularly and re-trains it to keep it up to pace with the new models.
