Our verdict on StealthWriter

StealthWriter is a browser-based AI writing assistant for rewriting AI-generated or AI-assisted text. It is aimed at writers, marketers, copywriters, researchers, professionals, agencies, and teams that want clearer phrasing, improved rhythm, more natural expression, and built-in AI detection. Users paste text directly into the browser, with no downloads or extensions required. Its focus is narrower than a general writing suite: humanization, rewriting, sentence-level analysis, and detection are central to the product.

The published plans show a freemium structure. The Free plan costs $0 per month and includes the AI humanizer, AI detector, AI deep scan, and Ghost 5.2 Mini. Starter is $20 per month, or $200 per year according to the published annual pricing, and adds Ghost 5.2 Pro and legacy models on the monthly plan. Plus costs $50 per month, Pro costs $100 per month, and Business costs $200 per month. Business adds priority team support, while Scale costs $400 per month and includes priority team support. Enterprise provides custom daily humanizations, custom daily AI scans, custom billing and procurement, dedicated support, and volume planning.

StealthWriter’s standout capability is its layered rewriting workflow. Users can choose light, medium, or aggressive rewrite levels, review alternative sentence rewrites, and scan text sentence by sentence. Multiple rewrite models, including Ghost 5.2 Mini and Pro, give paid users more model options, while the built-in detector includes V1 and V2. Daily humanization and AI scan limits shape usage across the service. StealthWriter suits individuals and teams specifically seeking AI-humanization and detection features in a web interface; buyers needing API access or a broader platform should consider a different type of tool.

I've used StealthWriter myself and this is my honest opinion — nobody paid or asked me to write it.
