What Is StealthWriter?
StealthWriter (stealthwriter.ai) is an AI content rewriting tool that transforms AI-generated text into human-like content. It positions itself as a "stealth writer" that helps users bypass AI detection tools by rewriting content from ChatGPT, Claude, and other AI assistants. The tool supports multiple languages including English, Spanish, and French, and includes a built-in AI detection feature.
StealthWriter works by analyzing AI-generated text and rewriting it to remove the patterns that AI detectors flag. It claims to achieve a "100% human score" on detection tools, though independent testing shows more modest results. The platform offers a clean interface and supports content up to 5,000 words per submission.
The main drawback of StealthWriter is its pricing and limited features. At $19.99 per month, it costs nearly three times more than comparable alternatives. It also only offers a single humanization mode, which means less control over how your content is rewritten. For users who need different output styles for academic, creative, or professional content, this is a significant limitation.
HumanizerAI: A Better Stealth Writer Alternative
HumanizerAI delivers everything you'd want from a stealth writer — but at $7 per month instead of $19.99. That's 65% less for a tool that actually achieves a higher bypass rate. While StealthWriter claims 100% but delivers closer to 85% in independent tests, HumanizerAI consistently hits a 96% bypass rate across GPTZero, Turnitin, Originality.ai, Copyleaks, and ZeroGPT.
Where HumanizerAI truly pulls ahead is features. Three humanization modes — Standard, Academic, and Creative — let you tailor the output to exactly what you need. Writing a research paper? Academic mode preserves formal tone and citation patterns. Blog post? Creative mode adds natural variation and personality. StealthWriter only offers one mode, giving you far less control over the final result.
HumanizerAI also includes a built-in AI detector so you can verify your content passes detection before submitting or publishing. Plus, there's a free tier that lets you test the tool with real content before paying anything — no credit card required. StealthWriter hides pricing behind a signup wall, making it impossible to evaluate the cost before committing.
Key Differences Between HumanizerAI and StealthWriter
Pricing: $7/mo vs $19.99/mo
HumanizerAI costs $7 per month while StealthWriter charges $19.99 per month. That's a $156 savings per year. Both tools serve the same purpose — making AI content undetectable — but HumanizerAI delivers more features at a fraction of the price. For students, freelancers, and small teams, this difference adds up fast.
Bypass Rate: 96% vs ~85%
HumanizerAI achieves a 96% bypass rate across all major AI detectors. StealthWriter claims perfect scores but independent testing shows results closer to 85%. This matters when you're submitting academic papers through Turnitin or publishing content that needs to pass Originality.ai — an 11% difference means significantly fewer false positives.
Humanization Modes: 3 vs 1
HumanizerAI offers Standard, Academic, and Creative modes, each optimized for different types of content. StealthWriter only provides a single mode, which means every piece of content gets the same treatment regardless of whether it's an essay, blog post, or marketing email. More modes = more control = better results for your specific use case.
Free Tier: Yes vs No
HumanizerAI lets you try for free with no credit card required. You can test the tool with your own content and see the results before deciding to pay. StealthWriter requires you to sign up and commit before you can even see how the tool performs on your text. HumanizerAI's transparent approach means you never have to take a leap of faith.
Language Support: 50+ vs Limited
HumanizerAI supports 50+ languages, making it useful for international students and multilingual content creators. StealthWriter supports English, Spanish, and French — just three languages. If you write in German, Japanese, Portuguese, or any other language, HumanizerAI is the only choice.
Meaning Preservation
Both tools aim to preserve the original meaning of your text, but HumanizerAI's engine is specifically trained to maintain factual accuracy, tone, and intent. StealthWriter sometimes introduces awkward phrasing or slightly shifts the meaning during rewriting. HumanizerAI ensures your key points come through intact every time.
