Putting Stealthly to Test: Does It Really Bypass AI Checkers?
To evaluate Stealthly's effectiveness, we conducted a series of tests using various AI-generated texts and popular AI detection tools. Here's what we found:
GPTZero Test:
We began with a paragraph generated by ChatGPT and ran it through GPTZero, which immediately flagged it as AI-generated.

After processing the same text through Stealthly, we re-tested it on GPTZero. The result? GPTZero classified the Stealthly-processed text as human-written, with a significantly lower perplexity score.
Originality.ai Challenge:
Next, we tested another article created by ChatGPT on Originality.ai, which initially returned a 100% AI probability.
After humanization with Stealthly, the same content scored as 98% human-written on Originality.ai, demonstrating Stealthly's ability to fool even more sophisticated detectors.

Copyleaks Test:
Finally, we challenged Stealthly with Copyleaks. The AI-generated article initially scored as AI-generated.
After Stealthly's processing, the same article received a "Human-Generated Content" classification.
Readability and Quality Assessment:
Beyond just bypassing detectors, we had human editors review the Stealthly-processed content. They found that the humanized text maintained readability and coherence, often noting improvements in flow and natural language use compared to the original AI-generated content.
Concluding the Tests
Our tests indicate that Stealthly is remarkably effective at bypassing a wide range of AI detection tools. It consistently transformed easily detectable AI content into text that passes as human-written, all while maintaining the original meaning and improving overall quality.
