A low-cost grammar checker with a broad set of AI writing tools.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
GrammarCheck.ai is an online writing tool for students, book authors, bloggers, and non-native English speakers. It checks grammar, spelling, and punctuation, presents automatic correction suggestions, and supports one-click corrections. Users can enter text, paste content, or upload files. Beyond core proofreading, it includes paraphrasing, plagiarism checking, AI-generated-text checking, AI text humanization, text summarization, and punctuation checking.
The freemium structure makes the product accessible for occasional writing work. The Free Plan includes 5,000 credits, limited grammar checking, and a 650-word submission limit. Lite Monthly costs $4 per month and adds 40,000 credits, a 2,000-word submission limit, and history. Pro Monthly costs $7 per month, with unlimited credits, a 6,000-word submission limit, and history. Annual options start with Lite Yearly at $2.50 per month when billed annually, while Pro Yearly costs $4 per month when billed annually and includes unlimited credits, a 6,000-word submission limit, and history.
Platform coverage is a notable part of the offering: GrammarCheck.ai is listed for web, Linux, iOS, Android, macOS, and Chrome. The breadth of adjacent tools may suit users who want proofreading alongside rewriting, originality checks, AI-text analysis, humanization, and summaries. However, the plan limits remain important for longer submissions, especially on the free and Lite tiers. Choose it if low pricing and multiple AI writing utilities matter more than a narrowly focused grammar workflow. Users seeking a dedicated grammar-only tool or clearly defined language coverage may prefer an alternative.
