iGrammar is an AI-powered grammar checker and writing assistant for students, professionals, writers, and English learners. It covers grammar, spelling, punctuation, sentence structure, clarity, tone adjustment, rewriting, paraphrasing, summarization, proofreading, plagiarism checking, document and image uploads, and writing analytics. Access spans a web editor, macOS app, iOS app, Android app, Chrome extension, and API, making it suited to people who write across desktop, mobile, and browser-based workflows.

Pricing is straightforward across two listed plans. The Free plan costs $0 and includes grammar correction, spelling checks, summarizing, paraphrasing, and browser extension access. The Unlimited plan costs $10 per month when billed monthly and adds unlimited grammar corrections while retaining the same listed capabilities. A 3-day trial is also available. Apple offers separate in-app subscription prices, which may differ by storefront or region. For buyers comparing grammar tools, the main distinction is the move from free core assistance to unlimited grammar corrections rather than a large change in the named feature set.

Platform coverage and integrations are central strengths. The browser extension supports workflows involving Google Docs, Gmail, LinkedIn, X, Slack, Facebook, Instagram, Notion, Google Sheets, Jira, Medium, ChatGPT, and Microsoft Word. Mobile keyboard integration extends correction and writing assistance to mobile devices, while the API provides an option for software-based access. iGrammar fits users who want one tool across many writing contexts and need more than correction alone. Someone seeking only a focused grammar checker may find the broader rewriting, summarization, tone, upload, plagiarism, and analytics features unnecessary.
