In their own words
RewritePal
RewritePal is a writing assistant for paraphrasing, grammar correction, AI text humanization, and editing longer documents. Its editor offers preset and custom tones, role and language options, and controls for making output shorter or longer. It is described as serving students, professionals, marketers, and others seeking clearer writing. RewritePal is available on Android, iOS, Linux, macOS, the web, Windows, and as an extension. The Chrome extension can rewrite selected text in supported fields, run optional local English Inline Fix checks, or use a popup in unsupported editors. In Google Docs, Selection Rewrite and Inline Fix are not supported, though the popup remains available. AI rewriting happens after the user selects a rewrite action, and internet access is required even in the installed web app. RewritePal says submitted writing is not used to train its own AI models and is not intentionally retained in its application database or logs after processing, except for saved documents and custom tones. AI providers may process submitted text, and the policy does not promise zero retention for every request.
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.
