The AI rewrite done by stealth writer is truly amazing. It goes undetectable in turnitin. Though, there is one problem when we scan with V2. Whenever we change the results with the undetectable alternatives, it shows the AI detection score more than what it's showing before. I recommend you to check the V1 scan results once again, so that it'll also provide accurate results.

Not recommended, It's output is 100% a spun/AI-rewritten article. I rewrite the subheadings to make them "unique," but it didn't understand the context of the article. What happened to the heading and the "Best For" line: The Brand Name: It changed "Casely" to "The Honourable Drummond House". The Target Audience: It changed "Best Overall Value" to "Best Residential". WHAT RUBBISH IS THIS? This happened this tool looked at the word "Case" (as in a phone case) or "Casely" and pulled a lit

I’ve been using StealthWriter for a long time now, and honestly, it’s still the best humanizer I’ve found. I’ve tried a few others, but I always end up coming back to this one because it actually works and doesn't break the bank. What I really appreciate is that they don’t just let the tool sit there—they’re clearly working on it every day to make sure it stays ahead of the newer detectors.

I really wish I had read more reviews before signing up for this. Honestly, it's been one of the worst experiences I've had with any service, and I feel like I need to warn other people before they make the same mistake I did. When I first joined, everything seemed fine. The promises were big, the marketing looked professional, and I genuinely believed I was getting something worth paying for. But it didn't take long before the cracks started showing. They keep changing the limits and the terms

Fraudlent service. I am unable to login to my account after sometimes of making a premium purchase. I tried contacting support but they never respond or resolve the issue.

Okay, I need to know if anyone else is experiencing this, or if it's just me. For the past few months, I've been using StealthWriter (and similar tools, not gonna lie) to "humanize" my drafts, mostly just to help with flow and structure before I do a final polish. It's been pretty reliable – never had an issue with AI detection. But ever since this new Turnitin "AI Integrity Scan" or "Authenticity Analytics" update rolled out (my university just implemented it last week), everything has gone sid

So with Turnitin’s August 27th update, a lot of people noticed something: 👉 Stealth Writer and most of the old “AI bypassers” are no longer working. False positives everywhere, flagged text even after heavy humanizing, and students/teachers alike are confused. A lot of people are asking if Turnitin actually trained their AI detector directly on Stealth Writer. While Turnitin hasn’t disclosed what training data they used, here’s what’s more likely happening: They trained on a huge mix of AI-gene

DONT BUY THIS as there is no option to UNSUBSCRIBE OR REMOVE CARD DETAILS , no one responds to either mails or chats ..it gets deducted once plan ends ..i am really stuck with this, never seen any site having no UNSUBSCRIBE button at all. when u want to remove card details, it says active subscription going on, when its about to end in few days n already money is deducted upfront 1 year back

I am writing to follow up once again regarding my previous messages, as I have not received any response so far. As mentioned earlier, I subscribed to your program during a promotional offer, but the discount code was not applied and the full amount was charged. Despite contacting you more than six days ago, there has been no reply to date. I kindly request that this issue be reviewed urgently and that the extra amount be refunded or the agreed promotional discount be applied to my subscription.

NEGATIVE trustpilot

I requested a refund immediately after an auto-renewal (0 usage). I explained my situation, but instead of a human response, I received a generic bot reply telling me to 'upgrade my plan' completely ignoring my refund request. This support is unresponsive and unhelpful. Be careful with this company!

Stealthwriter has been one of the strongest, best humanizers for me. Its interface is high quality and can be easily navigated through and it can easily bypass AI detectors such as GPTZero and Turnitin for example. Highly recommended to use

NEGATIVE reddit

This tool is not worth it. It has so many models I don't even know which one to use to bypass GPTZero for example. Switched to Rephrasy according to a recommendation from the r/AiHumanizer Subreddit.

POSITIVE reddit

So, I decided to give StealthWriter AI a shot. For a whole month, I used it to help me write blog posts. I was curious: Would it really make my content sound more human? Would it help me bypass those pesky AI detectors? Let’s dive in. The Experiment Begins First off, I have to say, using StealthWriter AI was pretty easy. You just paste your AI-written content in, and it spits out a new version that sounds more like a real person wrote it. I was impressed with how quickly it worked. Did it Work?

Questions

Frequently asked

What is StealthWriter?

StealthWriter is an AI tool that transforms AI-generated content from tools like ChatGPT, Claude, and Gemini into naturally human-sounding text. It includes built-in AI detection scanning to verify results and offers multiple rewrite intensity levels to control how extensively the text gets modified while maintaining the original meaning and intent.

How fast does StealthWriter process content?

StealthWriter processes and humanizes content in under 10 seconds. This fast processing time allows for quick workflow integration when you need to humanize AI-generated text efficiently.

What are the different rewrite intensity levels?

StealthWriter offers three rewrite intensity levels: light, medium, and aggressive. These levels allow you to control how extensively your AI-generated text gets modified, giving you flexibility based on how much humanization your content needs.

Does StealthWriter include AI detection capabilities?

Yes, StealthWriter includes a built-in AI detector that allows you to scan text before and after humanizing to verify results. The tool provides sentence-by-sentence analysis with color-coded highlights showing exactly which portions were flagged as AI-generated, eliminating guesswork about detection risks.

Is StealthWriter free to use?

StealthWriter offers a free plan with 10 humanizations and 10 AI scans per day, with a 1,000-word limit per input. Paid plans start at $20 monthly for the Starter plan (50 daily humanizations with 5,000-word limit) and go up to $400 monthly for the Scale plan (2,000 daily humanizations).

Can I customize individual sentences in the rewritten content?

Yes, StealthWriter allows you to click on any sentence to view multiple alternative rewrites and fine-tune the output. This feature lets you match your preferred voice and tone by selecting from different rewrite options for specific sentences.

What's the maximum word limit for content input?

The free plan has a 1,000-word limit per input, while all paid plans support up to 5,000 words per input. This applies to both the Starter plan at $20/month and higher-tier plans including the Scale plan.

Does StealthWriter store my content after processing?

No, StealthWriter doesn't store user content after processing. The platform processes your text to humanize it and provide detection analysis, but doesn't retain your content once the session is complete.
