Introduction

In recent years, the intersection of artificial intelligence and content creation has become a prominent frontier of technological advancement. Since November of 2022, the rise of platforms such as ChatGPT has highlighted this synergy, witnessing a remarkable growth with over 100 million users joining the platform. This surge indicates that a significant volume of global content, whether in the form of academic articles, blog posts, or social media updates, is now either authored by AI or crafted with its assistance.

The widespread adoption of AI for content creation has precipitated the emergence of AI detectors. Originally developed for academic institutions to identify machine-generated content in research and assignments, these detectors have found applications beyond the academic realm. From the gaming industry to the intricate processes of job recruitment, and even in the algorithms powering search engines, the ability to discern between human and AI-generated content has become a valuable asset.

However, as with any technological advancement, a counter-movement has emerged. In the wake of AI detectors, a new breed of services has arisen: undetectable AI platforms. Pioneers in this space, such as StealthGPT, UndetectableAI, ConchAI, and StealthWriter, harness the power of advanced algorithms to generate or rephrase content, aiming to outsmart AI detectors. This evolving dynamic has sparked a digital "cat and mouse" game, with each side continuously innovating to gain the upper hand.

The primary objective of this paper is to delve into this intricate dance of detection and deception. We aim to examine the leading AI detection services juxtaposed against the top undetectable AI services to determine which of the latter stands out as the most adept at evading detection. While we may infer the efficacy of certain AI detectors based on our findings, it is essential to note that the core focus of this paper remains on evaluating the prowess of undetectable AI platforms.

Methodology

Our research utilized a structured and systematic approach to evaluate the proficiency of undetectable AI services. We initiated the process by selecting 100 random textual inputs, which were then provided to each of the undetectable AI services: StealthGPT, StealthWriter, Conch AI, and Undetectable AI. These services were tasked with rephrasing the given inputs. The resulting 100 outputs from each service were subsequently subjected to analysis by each AI detector.

Metrics Utilized

To gauge the effectiveness of the undetectable services, we employed scores provided by three leading AI detectors: GPTZero, Originality AI, and Copyleaks. While these detectors offer a multitude of metrics, we handpicked specific scores that best delineated the detectability of AI-generated content:

GPTZero

The metric of interest was `completely_generated_prob`, representing the probability that a given document was entirely AI-generated. It spans a range from 0 to 1, with 0 indicating no AI involvement and 1 signifying complete AI authorship.

Originality AI

This detector provides two key metrics:

  • "original": This score, ranging from 0 to 1, indicates the likelihood of human authorship, with 0 suggesting no human content and 1 implying the content was entirely human-generated.

  • "ai": Serving as the converse of the `original` score, this metric also ranges from 0 to 1, where 0 indicates no AI content and 1 denotes complete AI generation.

Copyleaks

Distinct from the other detectors, Copyleaks offers binary scores:

  • "human": A score of 1 suggests human authorship, while 0 implies AI generation.

  • "ai": This is the inverse of the `human` score.

  • Here is a new bullet point for the demonstration

Composite Score Calculation

To derive a comprehensive assessment of each undetectable service's performance, we aggregated the scores from all detectors. The process involved computing the average scores for originality, copyleaks, and GPTZero for each undetectable service. Thereafter, a composite score was established, blending the strengths and weaknesses of each service against every detector, providing a holistic measure of their efficacy.
