Several modes are free; the pricing explanation gives a 600-word limit, and says upgrading to Pro can increase the limit to 1500. Apps and API options span Android, iOS, and web. The full-article API endpoint accepts up to 5000 characters per content check. The maker identifies students, freelancers, academic writers, and SEO content creators as intended users.

StealthWriter
StealthWriter rewrites AI-generated or AI-assisted text to improve phrasing, flow, and clarity, and includes an AI detector. Its humanizer provides light, medium, and aggressive rewrite levels. The detector estimates whether submitted text may be flagged as AI-generated and gives overall and sentence-level feedback. It accepts text from tools such as ChatGPT, Claude, Gemini, Llama, Mistral, Copilot, and Jasper; listed supported languages include Spanish, French, German, Italian, Portuguese, and Dutch. StealthWriter runs in modern browsers on desktop, tablet, and mobile, with Android, iOS, and web listed as platforms. The free plan allows 10 humanizations and 10 AI scans daily, up to 1,000 words per input, and includes Ghost 5.2 Mini. Paid plans start at $20 a month and allow up to 5,000 words per input, with Ghost 5.2 Pro and Ghost Legacy also included. The public detector demo has a 500-word scan limit and daily limits. The maker advises reviewing rewritten text because a rewrite can alter details or how a claim is expressed.
