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.
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.
