Safe Search Kids
It is imperative that articles submitted by our writers are not only 100% unique, but also written by humans without the assistance of AI, particularly considering Google has been clear it will devalue content that is written by AI or simply a rehash of existing content. I use Copyleaks to ensure the authenticity of all content that gets posted to our site.

Frequently Asked Questions

We are able to recognize AI text patterns utilizing multiple techniques:

Our AI engine has been processing and learning how humans write as opposed to AI. Since 2015, we’ve collected, ingested, and analyzed trillions of crawled and user-sourced content pages from thousands of universities and enterprises worldwide to train our models to understand the text and sniff out the signals created by other AI. 

Also, utilizing AI technology, our AI detector can accurately recognize the presence of other AI-generated text and the signals it leaves behind, adding an additional layer of accuracy.

We strive to inspire authenticity and digital trust by creating secure environments to confidently share ideas and learn. And with that comes the responsibility to ensure complete accuracy, particularly around false accusations. To address this, we have taken several precautions, including: 

– Our detection and the algorithms that power it is designed for detecting human-generated text, versus AI-generated text, the latter of which gives less accurate detection and increases the likelihood of false positives.  

– To help accelerate our learning and refine the models used, we implemented a feedback loop where users can rate their results’ accuracy. This allows us to continually use examples of false positives, rare as they may be, to improve. 

– We only introduce new model detection after thorough testing. Once our internal team testing reaches a high confidence threshold, we leverage beta testers, giving an additional layer of assurance.  

The chance for content written by a human to be falsely labeled as AI-generated content is 0.2%, the lowest of any AI content detection platform.

At Copyleaks, our products are routinely undergoing independent verification of privacy, security, and compliance control in efforts to achieve certifications against global standards to earn and retain the trust of the millions of Copyleaks users worldwide. Our current Copyleaks certifications and compliance standards include SOC2, GDPR, PCI Payment Card Industry Data Security Standard, and NIST Risk Management Framework (RMF).

AI Content Detector looks at prose sentence-by-sentence within multiple forms of content, not just long-form prose. Text highlighted in various shades indicates the probability of AI content detected; some sentences might have been fully written by AI, while others might be interspersed with human-created content.


Our detection report highlights the specific elements of the text that have been written by a human and those written by AI, along with a confidence level, offering a new level of insight and transparency.
