Our verdict on WhiteSmoke

WhiteSmoke is English writing software for students, professionals, writers, executives, bloggers, governmental employees, and English learners. It checks grammar, spelling, punctuation, and style, while offering correction suggestions, rule explanations, contextual spelling checks, writing tutorials, templates, translation, plagiarism checking, and a multilingual dictionary. Access spans web, Windows, macOS, iOS, Android, browser extensions, and a grammar-engine API.

Pricing is structured around three annual-billing plans with monthly-equivalent prices. Web costs $10 per month and includes grammar checking, plagiarism checking, translation, and all browsers. Premium costs $13.33 per month and adds one-click proofreading, Microsoft Word and Outlook integration, and a one-computer license. Business costs $22.99 per month and includes a three-computer license, one-click proofreading, and phone customer support. A three-day trial provides a short evaluation period, while the annual payment structure suits buyers prepared to commit for a year.

WhiteSmoke fits people who want one writing product across browser, desktop, and mobile environments, especially when translation and plagiarism checking matter alongside grammar correction. Its integrations with Microsoft Word, Outlook, Office, Gmail, and web browsers broaden its place in everyday writing workflows. Buyers focused specifically on browser-based checking can choose Web, while users working in Word or Outlook should consider Premium. Business is the clearest fit for multi-computer access and phone support. It is less suitable for buyers seeking a free plan or flexible monthly billing, or for teams that need a license beyond the three-computer Business allowance.
