AI Detector

When a Language Model writes a sentence, it probes all of its pre-training data to output a statistically generated sentence, which is simply not how a human writes. It becomes apparent when analyzed against a vast corpus of human writing.

We can recognize AI text patterns utilizing multiple techniques.

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 how humans write as opposed to 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.

There are several significant differences between other AI detector tools and ours.

For example:

• Credible data at scale, coupled with machine learning and widespread adoption, allows us to continually refine and improve our ability to understand complex text patterns, resulting in over 99% accuracy—higher than any other AI detector—and improving daily.
• As an enterprise-based platform, we’re the only solution with seamless API and LMS integrations, allowing you to bring the power of AI Detector directly to your native platform and at scale.
• The AI Detector is the only platform to read source code, including AI-generated. Furthermore, it can detect source code at the function level, helping identify when code has been plagiarized or modified, even if certain variables have been altered or entire portions have been changed
• Our AI Detector does not flag Grammarly’s non-AI features, which include spell check and grammar, as AI. Another AI Detector, in their own analysis, flagged 20% of Grammarly’s non-AI features as AI content, an astounding 20% false positive rate. Read the full analysis.
• Our AI Detector, along with all of Copyleaks’ products, are fully GDPR-compliant and SOC 2 and SOC 3-certified, a global standard audited by KPMG, the leading auditing organization for certification, ensuring the privacy and protection of personal data.

The chance for content written by a human to be falsely labeled as AI-generated content is 0.2%, the lowest of any AI detector available. Nevertheless, we strive to inspire authenticity and digital trust by creating secure environments to share ideas and learn confidently, and that comes with 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 are designed for detecting human-generated text versus AI-generated text. Detecting AI text tends to give a lower accuracy 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 the accuracy of the results, which 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 testing reaches a high confidence threshold, we leverage beta testers, giving an additional layer of assurance.

Yes. In July 2023, four researchers from across the globe published a study on the Cornell Tech-owned arXiv, declaring Copyleaks AI Detector the most accurate for checking and detecting Large Language Models (LLM) generated text. Since then, additional independent third-party studies have been released, each one highlighting the accuracy and efficiency of the AI Detector.

Only certain features of writing assistants can cause your content to be flagged by the AI Detector as AI-generated.

For example, Grammarly has a genAI-driven feature that rewrites your content to help improve it, shorten it, etc. As a result, this reworked content could get flagged as AI since it was rewritten by genAI. 

However, the Copyleaks Writing Assistant does not get flagged as AI or any content that Grammarly changed to fix grammatical errors, mechanical issues, etc., because it does not use or uses minimal genAI to power these features or functionalities.

Yes. Our detection report highlights the specific elements of the text written by a human and those written by AI, even if the text has been interspersed.
