Published:April 17, 2025

Reading Time: 7 minutes

Chances are, you have used at least one of many AI tools to help with your articles, ad copies, assignments, and so on. While these tools are superb at writing articles, AI-generated content can easily be detected by tools like Turnitin, GPTZero, and so on.

This serves as a cause for concern for AI users seeking to maintain authenticity and avoid detection, especially in the marketing field or a school setting, where originality is non-negotiable.

That’s exactly why StealthWriter AI is your guy.

StealthWriter AI is a special software program that is specifically designed for the purpose of humanizing content written by AI.

In other words, it takes content written by AI and rewrites it in such a way that deceives AI detectors into believing that the content was written by a human.

In this review, we will discuss everything you need to know about StealthWriter AI. So grab a cup of coffee or tea, and let’s get started.

TL;DR

StealthWriter AI is a program that rewrites AI-written content to make it seem like it was written by humans.

Purpose: It converts AI-generated content into human-like text, helping users to avoid the innumerable AI tools used by schools, companies, and search engines to detect AI content. 

Key Features: This AI tool has 2 main functionalities: AI humanizer and AI detector. The Humanizer feature paraphrases text that has been generated by artificial intelligence software.

On the other hand, the AI detector reviews written content and provides feedback on the percentage of the content that was most likely generated by AI.

Another key feature of StealthWriter AI is its ability to generate/edit content that is free of plagiarism. Albeit, its content generation is limited to only those with a paid plan.

Best For: Social media content creators, students, bloggers, digital marketers, freelancers, SEO professionals, and content agencies seeking to produce undetectable AI content.

Pricing: StealthWriter AI offers a free plan. Its basic plan currently costs $20/month, the standard plan is $30/month, while the premium plan costs $50/month. ​

Alternatives: AIDetectPlus, Undetectable AI, Quillbot, etc.

Overview & Main Features

1. Humanizer Mode

StealthWriter AI

This is the primary feature of StealthWriter, and it works like magic. Using StealthWriter starts with typing your AI-generated content, followed by hitting the humanizer button to obtain your humanized text output in seconds.

  • Preserves original meaning
  • Rephrases sentence structure
  • Adds variation to tone and word choice
  • Bans repetitive AI syntax

2. Editor Mode

StealthWriter AI also allows users to edit content or complete text with AI generated content. For example, you can put in a body of incomplete text and have it write the conclusion or section for you.

  • It can be used for product descriptions, blog posts, or emails
  • Good for short content
  • Less robotic than raw AI output

3. Ninja & Ghost Models

StealthWriter gives you two major options to choose from on how your content is rewritten.

  • Ninja Model: It provides a quicker and less intricate rewriting. You should use this if you are looking for a quick fix.
  • Ghost Model: It provides a more intelligent and comprehensive rewriting. You should use this if you are looking for richer, more natural content. Please note that the Ghost model is only available on paid plans.

4. Built-In AI Detection Tool

Before or after rewriting, you can verify whether your content can be detected by AI detectors.

  • Displays percentage of text that was probably generated using AI
  • Helps refine until content passes the test
  • Works with all languages

It is vital that you always double-check before publishing your content

5. Plagiarism-Free Content

Since the tool completely rewrites the content, it prevents typical copy-paste problems and does not trigger plagiarism tools.

  • Ideal for schoolwork
  • SEO-friendly content
  • Helps preserve originality

6. Clean, Easy Interface

You definitely do not need to be a tech expert to use this powerful AI. The platform is simple to use:

  • Paste → Click “Humanize” → Copy

Best For

1. Students

As a student, using AI tools to write your essays exposes you to the risk of being caught by plagiarism checkers or AI detection software.

With StealthWriter AI, you can modify or paraphrase those AI-generated texts, thereby making them less detectable by plagiarism checkers and AI detection software.

However, you should always use StealthWriter AI responsibly. It was created to improve writing and not to promote cheating.

2. Bloggers & Content Creators

A good number of bloggers and social media content creators tend to make use of AI as a guide in producing their digital content.

However, just simply copying and pasting your content from AI without modifying and enriching it will make your content sound mechanical to your readers.

This problem can simply be solved by using StealthWriter to paraphrase that content. This will make your content sound more natural and, consequently, drive engagement.

3. Marketers & SEO Professionals

In the fight against plagiarism on the web, websites like Google now demand original content. As such, using content or ad copy that is fully generated by AI puts your site at risk of sanctions.

Digital marketers can use StealthWriter to modify AI-generated copies before uploading their ads. By doing so, you should be able to avoid being penalized by Google for uploading duplicate content.

In addition to this, StealthWriter will also reduce your risk of being sued by competing firms for plagiarism. 

4. Freelancers and Agencies

Freelance writers and content bureaus enjoy using AI in generating their articles so they can save time while creating as many articles as possible.

However, clients are only willing to pay for plagiarism-free content that is engaging and sounds natural.

By using StealthWriter, you should be able to deliver high-quality, original content and improve your productivity without setting off detection alarms.

5. Social Media Managers

Yes, social media managers can also reap benefits from the use of StealthWriter AI. Posts are expected to generate traffic and drive engagement only when they are creative and original.

Hence, posts that sound like that of a robot simply won’t suffice. Use StealthWriter AI to modify your AI-generated captions, tweets, and posts to make them relatable to your audience.

Alternative To

StealthWriter has a good number of competing AI software that perform similar functions and can serve as alternatives to users. Here is a list of top alternatives to StealthWriter AI:

1.  Undetectable AI

Just like StealthWriter, Undetectable AI performs the same function of rewriting text generated by AI in such a way that it passes AI detection tools.

It is usually used by students, content creators, or professionals who are trying to make it seem like their content was fully written or created by them.

However, StealthWriter offers more modes of rewriting text and also has more sophisticated features, like a built-in AI detector. This arguably makes it the better choice.

2. QuillBot

QuillBot is an AI tool that simply provides a complete writing solution to its users. It can be used to check for grammatical errors, check for plagiarism, detect if content was written by AI, and also paraphrase sentences to enrich their meaning.

However, in comparison to StealthWriter, its humanized content is not always able to bypass AI detectors successfully. Hence, you are better off using StealthWriter to humanize your content.

3. Paraphraser.io

This AI tool offers a wide range of features, including generating content, paraphrasing content, and humanizing content generated by AI.

It is a full-fledged AI writing assistant that can also be used to check for plagiarism and grammatical errors in writing. While paraphraser.io has a wider range of features, StealthWriter still stands out as the better tool for humanizing content generated by AI. 

4. AIDetectPlus

AIDetectPlus offers a wide range of features. It is quite similar to StealthWriter but with fewer features in the free plan. However, if you are going for a paid plan, AIdetectplus should be your preferred option.

Like QuillBot, it offers a complete writing solution to its users while also providing a powerful humanization tool. Another impressive feature is the fact that it has different modes tailored to different users.

Verdict: StealthWriter is one of the most balanced tools. It offers content rewriting, generation, detection, and user-friendly pricing.
