In their own words
SpinBot
SpinBot is a web-based article spinner and paraphrasing tool that rewrites text while aiming to preserve its context and intended meaning. Its paraphrasing page provides Standard, Random, and Longest modes, along with controls for requesting longer or shorter results and specifying words to ignore. The free version works without registration, and no installation is required. The Free plan costs nothing, supports up to 10,000 characters or about 1,000 words per rewrite, and displays ads. SpinBot names students, researchers, and bloggers as suitable users. The site also links to a grammar checker, summarizer, text spinner, and AI content detector, and points to QuillBot’s AI humanizer as an external processing tool. Its policy describes collection of contact and usage information, cookies, analytics providers, and security limits.
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.
