In their own words
Rewriter AI
Rewriter AI combines a paraphraser, grammar checker and summarizer for written content. The paraphraser is described for emails, essays and social media posts; the grammar checker reviews English writing for grammar, spelling and punctuation; and the summarizer condenses articles, papers or documents to key points while retaining context. The site says the service supports over a hundred languages and allows 250 words to be rewritten for free. Free users can add up to two protected words and generate at most three articles; article generation is described as a trial feature on the free plan. Starter costs $6.40 a month, billed annually, and includes 50,000 words per month, web access and API access. Business costs $16.40 a month, billed annually, and includes 3,500,000 words per month, of which 700,000 are non-English, plus desktop and web versions, keyword analysis and API access. Paid Starter and Business plans include 50 image generations per month. The API uses HTTP GET and POST requests, returns JSON and supports browser CORS. The listed platforms include API, Linux, macOS, web and Windows.
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.
