Best Undetectable AI Tools of 2023

November 9, 2023

As artificial intelligence capabilities continue to advance, the development of AI-generated content has also accelerated. Tools like ChatGPT and other language models can now produce lengthy, coherent texts that sound remarkably human.

However, as the use of AI writing has grown, so have AI detection systems aimed at differentiating human-authored pieces from those created by machines. Services like Turnitin, PlagiarismCheck, and GPT-3’s own detector GPT-Zero now analyze texts for patterns indicating non-human generation.

In response, a new category of “undetectable AI” services has emerged on the scene. These tools claim the ability to take AI-generated drafts and rewrite them in a way that disguises the original non-human origins in order to bypass detection. But do these services actually perform as advertised?

In this article, we evaluate the top undetectable AI platforms and test their evasion capabilities against leading detectors through a comparative analysis.

We overview the methodology, discuss the key findings, and analyze the practical implications and ethical considerations of utilizing stealth AI generation techniques.

How AI Detectors Work

Before examining tactics for stealthily sneaking by AI detectors, let’s briefly cover how these tools identify artificial content:

  • Analyze writing patterns – Detectors look for giveaways like repetitive phrases, simplistic sentences, and grammar mistakes.
  • Check text against databases – The text is compared against vast repositories of existing content to identify duplication.
  • Use natural language processing – NLP techniques identify patterns characteristic of algorithmically generated text.
  • Flag based on indicators – Content containing multiple suspicious signals is flagged as likely AI-written.

Overview of Undetectable AI Tools Evaluated

For our research, we selected four prominent services making claims about their invisibility to detection:


A popular tool that reworks AI-generated content using techniques like paraphrasing and rephrasing to remove tell-tale patterns.

Undetectable AI: 

An undetectable ai tool focusing specifically on generating academic papers, essays, and other student work stealthily.


Another widely used service applying similar disguising tactics through automatic post-editing of machine-generated drafts.

Conch AI:

 A conversational AI assistant that can undetectably generate texts on demand within natural dialog flows.

Methodology for Evaluating Evasion Capabilities

To test the effectiveness of each service, a standardized methodology is followed

  • Randomly generated 100 text samples of 200-300 words using the undetectable AI tools.
  • Analyzed the outputs using 3 leading detectors: GPT-Zero, OriginalityAI, and Copyleaks.
  • Had the detectors assess whether each sample appeared human-written or likely machine-generated.
  • Calculated composite scores averaging detection outcomes across all tools to rank performance.

Key Findings: StealthGPT Emerges as Top Performer

Analyzing the results revealed one undetectable AI service outshone the rest:

StealthGPT achieved the highest scores for generating human-written content on Originality AI and Copyleaks.

StealthGPT’s composite score combining results across all detectors was markedly higher than competitors. The study concluded StealthGPT demonstrated the most advanced capabilities for evading detection while producing human-like writing.

Interpreting the Results for Best Undetectable AI Tools

StealthGPT’s dominance suggests its evasion tactics and training methodology are more sophisticated compared to rivals. However, the landscape is perpetually evolving as new detection and evasion techniques emerge.

For consumers, StealthGPT appears to be the most promising solution currently available for bypassing plagiarism checkers and AI detectors when appropriate. But ethical usage and avoiding plagiarism remain paramount.

Tips for Bypassing AI Detectors

Here are some methods for sneaking AI-generated text past the bots:

Use Undetectable AI Services

Specialized tools like StealthGPT, UndetectableAI, StealthWriter and ConchAI can disguise AI-written text by rephrasing it to remove patterns that trigger detectors.

Seeing StealthGPT in Action

Let’s see StealthGPT doing its disguise work on a real AI-written paragraph.

First, I asked ChatGPT to write about the future of large language models (LLMs):

I ran this text through the Copyleaks detector, which correctly identified it as AI-generated:

Next, I used StealthGPT in rewrite mode with undetectability mode high to obscure any AI fingerprints from the paragraph:

Checking the StealthGPT version once again with Copyleaks shows that it now passes as human-written:

This quick test confirms that StealthGPT can reliably disguise AI-generated text to bypass AI detectors. The meaning is preserved while the writing style and patterns are modified to avoid trigging the bots.

Pretty cool to see StealthGPT fooling its fellow AI! This is why it’s the one of the top choice for sneaking past detectors when needed.

Manually Edit and Add Original Analysis

Adding your own voice through examples, opinions, and insights makes content appear more original.

Paraphrase Sources

Rewording cited passages in your own style hides duplicated text while still properly attributing sources.

Adjust Writing Style

Varying sentence patterns, word choices, and tone makes writing less formulaic and robot-like.

Hire Professional Writers

Experts can craft high-quality custom content calibrated to sneak past detectors.

Practical Applications and Ethical Considerations

While StealthGPT seems the most promising undetectable AI option based on our tests, several important caveats remain:

Potential Beneficial Uses:

  • Leveraging obscure sources imperceptible to plagiarism checkers
  • Maintaining a consistent writing style with AI assistance
  • Accelerating output through AI-powered collaboration

Ethical Risks and Limitations:

  • Academic dishonesty if passing off AI work as original
  • Reputational damage if disguising is exposed
  • Undermining integrity of assessments and evaluations

Key Recommendations for Responsible Usage:

  • Consider motivations carefully and use tactics judiciously
  • Manually edit and add unique insights after generation
  • Fully attribute AI contributions per citation guidelines
  • Prioritize developing skills through AI facilitation, not replacement

Frequently Asked Questions

How accurate are the best AI detectors in identifying machine-written texts?

Detectors have improved significantly but are not perfect yet. When used together, top systems can reliably flag the vast majority of AI content while minimizing false positives.

What are the risks of using undetectable AI services unethically?

Unethical uses risk plagiarism penalties, damage to reputation, and undermining integrity if work is presented as all-original when aided by AI. Tools should only be applied responsibly and within guidelines.

Can manual editing alone fool detectors?

While editing after AI generation can help, depending on tools like StealthGPT that specialize in automated disguising is usually more effective. Manual work remains an important complement.

Are there legitimate reasons to leverage undetectable AI?

Used transparently and selectively to supplement rather than replace human efforts, stealth systems could aid productivity and accessibility without compromising ethics when appropriate guidelines are followed.


As the capabilities of AI generators and detectors continue to develop in an ongoing “arms race,” maintaining truly imperceptible machine-generated content will become increasingly difficult. However, taking a blended approach through judicious human-AI collaboration using tools like StealthGPT responsibly suggests the most sustainable path forward that balances capabilities, responsibilities, and integrity. Continued research evaluating new techniques will also help establish best practices for applying this emerging technology responsibly and beneficially.
