AI text humanizer and detector for natural, polished writing
What is StealthWriter?
StealthWriter is a web-based AI text humanizer and detector that rewrites AI-generated or AI-assisted writing so it reads more naturally. The product is built for people who want drafts to sound polished and ready to publish while keeping the original meaning and key points intact.
It combines rewriting, detection, and sentence-level review in one browser workflow. Users can paste text, choose a rewrite level, scan for AI detection before and after humanizing, and refine individual sentences with alternate phrasings. The site also says the service is available on desktop, tablet, and mobile, with no public API and no browser extension yet.
What can StealthWriter do?
AI Detector
Checks text before and after rewriting so you can see what is likely to be flagged as AI-generated.
Deep Scan
Breaks text into sentences and highlights what is flagged, making it easier to review specific edits.
Alternative Rewrites
Offers alternative rewrites at the sentence level so you can fine-tune wording without starting over.
Fast Web Workflow
Returns output in seconds and is presented as a browser-based workflow rather than a downloaded app.
Model Options
Supports major world languages on the 5.1 model and notes Ghost 5.2 Mini as the default lightweight humanizer model, with Ghost 5.2 Pro for stronger coherence and readability.
Use Cases
“Humanize AI drafts”
Paste a draft from ChatGPT, Claude, Gemini, or another AI tool and rewrite it so it reads more naturally before publishing or submitting it.
“Review AI risk before publishing”
Check a draft with the detector first, then humanize it, and compare the before-and-after result to understand what changed.
“Refine language and style”
Use the sentence-level alternatives and rewrite levels to adjust tone, phrasing, and flow without rewriting everything from scratch.
“Edit from any device”
Work on the same browser-based tool across desktop, tablet, or mobile when you need to edit content without installing software.
“Polish AI-assisted writing”
Use the product for writing that needs natural-sounding phrasing, including student work, blog posts, marketing copy, research notes, and other professional drafts.
