Frequently Asked Questions
Is the free version good enough?
For basic grammar and spelling corrections, yes — the free tier is quite capable. However, tone detection, style improvements, plagiarism checking, and AI features require a Premium subscription.
Does Grammarly work offline?
Limited functionality is available offline in the desktop app, but full features (AI suggestions, plagiarism detection, tone analysis) require an internet connection to process text through Grammarly's servers.
Is my writing data private?
Grammarly states they do not sell your data. Enterprise plans include additional privacy guarantees including SOC 2 compliance, no data retention for training, and SSO integration. However, text is processed on their servers to provide suggestions.
