AI Detector Tool | AI Checker for ChatGPT, Gemini & Claude (2024)

When a Language Model writes a sentence, it uses all its pre-training data to make a response based on statistics. This is significantly different from how humans write. To our AI writing detector, the presence of an AI text generator becomes clear when compared to a large collection of human writing.

We can detect the latest models of the following LLMs:

  • ChatGPT
  • Gemini
  • Claude
  • Jasper 3
  • T5

You can experience free AI detection on a trial basis by registering for a free Copyleaks account.

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. Our data comes from thousands of universities and enterprises worldwide. We use that data to train our models to understand how humans write.

Also, utilizing AI technology, the AI detector can accurately recognize the presence of other AI-generated text. It knows how to identify and flag the signals it leaves behind. That attention to detail adds a layer of accuracy to the process.

Several significant differences exist between other AI detector tools and ours.

For example:

  • We use large-scale, credible data combined with machine learning and broad adoption to refine our understanding of text patterns. This results in over 99% accuracy—better than any other AI detector, and it’s improving daily.
  • As an enterprise platform, we offer seamless API and LMS integrations, allowing you to bring AI Detector directly into your system at scale.
  • The AI Detector is one of the most advanced platforms for reading and analyzing source code, including AI-generated code. It detects plagiarism even when code has been modified, such as altering variables or entire sections.
  • Our AI Detector doesn’t flag non-AI features of Grammarly, like spell check and grammar. In contrast, another AI detector incorrectly flagged 20% of Grammarly’s non-AI features as AI content—a significant 20% false positive rate.
  • All Copyleaks products, including the AI Detector, are fully GDPR-compliant and SOC 2 and SOC 3-certified, ensuring the privacy and security of personal data audited by KPMG.

Our models need a certain volume of text to accurately determine the presence of AI. The higher the character count, the easier it is for our technology to determine irregular patterns, which results in a higher confidence rating for AI detection.

The ideal text requirements for each of our AI offerings are as follows:

AI Detector Browser Extension

Minimum: 350 characters

Maximum: 25,000 characters

AI Detector Web-Based Platform

Minimum: 255 characters

Maximum: 2,000 pages (There is no character maximum)

The likelihood of human-written content being mistakenly labeled as AI-generated is just 0.2%—the lowest among AI detectors.

We’re committed to fostering authenticity and digital trust by creating secure environments for idea-sharing and confident learning. Ensuring complete accuracy, especially in avoiding false accusations, is vital to this mission.

To address this, we’ve taken several precautions:

  • Our algorithms are designed to recognize human-generated text. Focusing on AI detection alone tends to lower accuracy and increase false positives.
  • We’ve implemented a feedback loop where users can rate result accuracy. This helps us learn from rare false positives and continuously improve our models.
  • We only introduce new model detection after thorough testing. We use beta testers for added assurance once internal testing meets a high confidence threshold.

Yes. In July 2023, four researchers worldwide published a study on the Cornell Tech-owned arXiv. The study declared 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 has highlighted the AI detector’s accuracy and efficiency.Read more about these third-party studies.

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

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. It won’t flag content that Grammarly changed to fix grammatical errors, mechanical issues, etc. This is because it does not use (or uses minimal) genAI to power these features.

At Copyleaks, our products routinely verify privacy, security, and compliance control independently. We aim to achieve certifications against global standards. We believe this is the clearest way to earn and retain the trust of the millions of Copyleaks users worldwide.

Our current Copyleaks certifications and compliance standards include:

  • SOC2 & SOC3
  • GDPR
  • PCI Payment Card Industry Data Security Standard
  • NIST Risk Management Framework (RMF)

Yes. Our detection report highlights the specific elements of text written by humans and labels these separately from those written by AI, even if the text has been interspersed.
