GrammarPro review
A simple web checker with broad basic corrections and a permanent free plan.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
GrammarPro is a browser-based AI writing checker for students, professionals, writers, and non-native speakers. It focuses on core writing correction in a simple web app, covering grammar, spelling, punctuation, clarity, formal-tone rewriting, and concise-writing suggestions. Corrections are streamed in real time, and inline explanations provide context for suggested changes. Basic use requires neither installation nor signup, while text processing is handled through OpenAI’s API.
Pricing is structured around a permanent Free plan and two Pro options. Free allows three grammar checks per day without an account or five when signed in, with a 500-word limit and all six checking modes. Pro Monthly costs $7.99 per month and adds unlimited checks, a 5,000-word limit, priority processing, all six modes, and the ability to cancel anytime. Pro Annual costs $59.99 per year with the same listed features. The paid plans suit users who need frequent checking or longer submissions, while the free tier fits occasional short corrections.
The main trade-off is platform scope. GrammarPro runs on the web and does not include a browser extension, desktop app, or mobile app, so it is better suited to text pasted into a browser than to writing workflows spread across installed tools. Its feature set is broad for basic correction, including tone and style suggestions, but buyers seeking integrated editing across multiple devices or applications should consider a product with wider platform coverage. Choose GrammarPro for accessible, straightforward correction; choose an alternative if native apps or embedded writing assistance are essential.
