GrammarPro is a browser-based AI checker for grammar, spelling, punctuation, clarity, tone, and concise writing. Its six modes are Grammar, Spelling, Punctuation, Clarity, Formal Tone, and Concise Writing. Corrections appear word by word in real time and include explanations for suggested changes. The service says it supports more than 30 languages; its About page names English, Spanish, French, German, Portuguese, Chinese, and Japanese. The free plan is free, allows three daily checks without an account or five when signed in, and limits each request to 500 words. Pro Monthly costs 7.99 USD per month, while Pro Annual costs 59.99 USD per year; both provide unlimited checks and 5,000-word requests. GrammarPro works in a browser on any device without installation. It has no browser extension, desktop app, or mobile app. Submitted text is sent to OpenAI’s API and is not stored after processing; the service advises against entering sensitive personal information.
Who it is for
GrammarPro suits students, professionals, non-native English speakers, writers, and bloggers needing browser-based writing checks. The free tier fits shorter, occasional requests.
