Phrasera vs Rewriter AI

Phrasera is a browser-based multilingual AI writing toolkit for paraphrasing, grammar checking, summarizing, detecting AI text, checking plagiarism, generating citations, and translating. It runs on desktop, tablet, or phone without installation and supports 28 languages, including Bahasa Indonesia, Malay, Javanese, Tagalog, Vietnamese, Thai, and Arabic. Paraphrasing offers Standard, Fluent, Formal, Simple, Creative, and Academic modes. The Free plan costs nothing and includes all seven tools, 25+ languages, runs of up to 1,200 words, and a plagiarism originality preview. Premium costs $9 a month and permits up to 25,000 words per run, full source-matched plagiarism scans, higher daily limits, priority speed, and saved bibliographies and history. Team costs $7 per user per month and adds centralized billing, shared style presets, an admin dashboard, and onboarding support. Phrasera says pasted text is processed securely, not sold, and not used for model training without explicit opt-in. Users can delete accounts, export history and bibliographies, and opt out of product-improvement sharing. The site advises reviewing generated results before use.

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.
