In their own words
Phrasit
Phrasit is a web hub of text, citation, grammar, and study tools for students, professionals, writers, and creators. Its tools include paraphrasing, grammar checking, summarizing, tone rewriting, translation, AI chat, and writing generators. The paraphraser offers nine modes and a strength dial. Its citation generator covers APA 7, MLA 9, Chicago, Harvard, and IEEE across 30 source types; the AI detector reports a likelihood band rather than a percentage. Phrasit has a free plan with a 150-word run limit and 30 AI runs per month, and paid plans start at $4.00 per month. Basic costs $4.00 per month and allows 600 words per run and 400 runs monthly. Premium costs $7.00 per month and adds PDF and DOCX uploads, while Unlimited costs $20.00 per month and includes bulk document uploads. Phrasit says it does not retain AI request text after responding. Text entered into its word counter, case converter, reading-level analyzer, and text comparator stays in the browser. AI requests go to Anthropic’s API, and grammar checks are sent through LanguageTool.
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.
