AI text rewriting tools are changing quickly. Stealth AI Writer describes itself as a “humanizer” which not only makes AI text sound natural, but produces its own AI detector.
Starting at $20/month and a limited free plan, Stealth AI Writer competes with big names like Undetectable AI, HIX.AI Bypass, and Humanize AI.
This review discusses what StealthWriter is, features and pricing, and how it stacks up to alternatives.
What is Slealth AI Writer?
StealthWriter is an AI-powered rewriting and detection platform.
It advertises itself as a tool for writing sth that sounds natural instead of robotic. Unlike a few different tools that are only focused on getting around detectors, StealthWriter focus on SEO-friendly rewrites and content polishing.
It offers two models:
- Ninja Model: included in free plans, built for basic humanization.
- Ghost Model: available in paid tiers, marketed as higher quality and superior detection bypass features.
The tool also has a free AI detector, which states it has 99.8% accuracy, and can detect multiple languages.
StealthWriter states that content enhancement for marketing purposes, SEO, and blogging is what is emphasized, rather than academic content.

Key Features of Stealth AI Writer
Humaniser Model: Ninja and Ghost
The main purpose of StealthWriter is to rewrite text.
The Ninja Model is free, limited to 300 words per request, and is marketed as good enough for most casual uses.
The Ghost Model is included with paid plans, supports more words per request, and is marketed as better, having stronger natural sounding rewrites, and more likely to pass through AI detectors.
Both models are focused on toning down the robotic tone, making the outputs more fluid for blog posts, ad copy, and social media post updates.
AI Detector Functionality
StealthWriter has an AI detector tool, too.
According to the company, it works with “all languages” and is reportedly 99.8% accurate. And, it’s free, so it can even be easily used without a paid plan.
This type of tool can be helpful for a last-minute check before publishing content, especially in cases where teams want to ensure content passes AI content filters.

FAQs For Stealth AI
Can Stealth AI reliably bypass AI detectors like Orifinality.ai, GPTZero, Copyleaks, and Turniitn?
It states it has strong detection bypass, especially with the Ghost model. However, there is no tool that can guarantee 100% will work. Pass rates will differ based on the detector, updates, and complexity of the text. Users tend to often pair StealthWriter with manual editing for the best results.
Is there a free plan or trial, and what are the word limits per request/day?
Yes. The free plan allows you to use the Ninja model for a request of up to 300 words only, and a maximum of 5,000 words per day. For small testing this is fine, but if you are looking to create long-form content this won't be sufficient.
What are the paid plan prices and what do “Ninja” vs “Ghosr” model allowances include?
- Basic ($20-per month): Ghost words for 20K total - Unlimited Ninja words.
- Standard ($35-per month): Ghost words for 50K total - Unlimited Ninja words.
- Premium ($50-per month): Unlimited Ghost words - Unlimited Ninja words.
Ninja works off the free/basic plan; Ghost is more advanced and paid tiers only.
How do new users sign up and where is the login portal?
Users create an account on the official StealthWriter website by providing a name, email, and password. After email verification, they log into the dashboard portal of the site to get to the Humanizer and Detector tools.
Why do some outputs still sound awkward or change meaning, and how to mitigate that?
AI rewriting is not always perfect. Sometimes it "loses" nuance or sounds a little "off." To improve this:
- Chunk the text into smaller sections.
- Change the settings (Ninja vs Ghost).
- Read and lightly edit the outputs for clarity, clarity and accuracy.
