October 21, 2025October 20, 2025 by worldstan.com

This review explores the effectiveness of AI humanization tools like Grubby AI and ChatGPT, revealing their strengths and limitations in creating natural-sounding, AI-generated content capable of bypassing detection tools.

Comprehensive Review of Grubby AI: Does It Live Up to Its Promises as an AI Humanizer?

In the rapidly evolving AI landscape, tools that claim to humanize AI-generated content are gaining popularity. One such tool is Grubby AI, marketed as an AI humanizer designed to make machine-written text sound more natural and human-like. But does it deliver on its promises? Our in-depth review explores its effectiveness, comparing it with ChatGPT and current AI detection tools.

What is Grubby AI?

Grubby AI is an AI humanizer that promises to transform AI-generated content into more natural, human-like writing with just a few clicks. Users simply sign up, input their AI-written text, and click “Humanize” — the tool then returns an adapted version that aims to bypass AI detectors and appear more authentic.

Effectiveness and Limitations of Grubby AI as an AI Humanizer

To evaluate Grubby AI, I conducted a series of tests:

Generated four AI-written samples.
Applied the Grubby AI humanizer on each.
Fed the humanized results into popular AI detection toolssuch as Winston AI, Originality AI, QuillBot, and Undetectable.ai.

The detection results revealed the following:

Detector	Humanized Content	AI-Detection Score (0-100%)	Interpretation
Winston AI	Humanized Text	55%	Still AI-Detected
Originality AI	Humanized Text	99%	Fully Fooled
QuillBot	Humanized Text	97%	Fully Fooled
Undetectable.ai	Humanized Text	45%	Slight suspicion, partially fooled

Average human score across tests: 61.56%

Conclusion:

These results highlight significant shortcomings. An effective AI humanizer should achieve detection scores nearing 99%, indicating near-perfect human-like quality. Currently, Grubby AI hovers around 60%, which is insufficient for reliable humanization, especially if the goal is to bypass AI content detectors.

Additionally, the free version limits users to only one short text sample, prompting payment thereafter—a questionable value proposition.

Comparing Grubby AI with ChatGPT as a Humanizer

To explore alternative options, I repeated the test using ChatGPT to humanize the same AI-generated texts.

AI Detector	ChatGPT-Humanized Text	Detection Score (0-100%)	Effectiveness
Winston AI	Humanized Text	65%	Still Detects AI
Originality AI	Humanized Text	99%	Fully Fooled
QuillBot	Humanized Text	98%	Fully Fooled
Undetectable.ai	Humanized Text	52%	Partially fooled

Average human score with ChatGPT: 72.06%

This indicates that ChatGPT outperforms Grubby AI significantly in generating more human-like content capable of fooling advanced AI detection tools.

Final Verdict & Recommendations

Based on our assessments:

Grubby AIcurrently fails to reliably produce humanized content that passes AI detection.
ChatGPToffers a more effective, free alternative that consistently produces more natural-sounding text.

In summary:

As a trusted AI Humanizer and content creator, relying on current automation tools for humanization is unreliable. Instead, investing time in creating original, authentic content remains the best strategy for authentic engagement and avoiding AI detection pitfalls.
