Grammarly for Android user guideA writing tool for grammar, tone, and clarity in supported mobile apps. Grammarly for Android is a floating assistant alongside your existing keyboard; iPhone uses a keyboard integration. It improves text rather than executing connected-app tasks.
Professionals and students who want polished, error-free writing in emails, messages, documents, and social media on mobile
Users who want fast swipe typing and next-word prediction as their primary features, anyone looking for cross-app task execution, or users who prefer fully offline keyboards
Advanced grammar and tone checks use cloud processing. Review Grammarly's privacy policy if handling sensitive, confidential, or work-related text.
Supported apps, permissions, and available suggestions differ by platform. Some writing features require Grammarly Pro. Android users keep their existing keyboard and review the assistant's overlay and Accessibility access.

Quick answers about Grammarly Keyboard
Is Grammarly Keyboard the best for writing?
Consider Grammarly when your main need is grammar and rewriting in supported apps. On Android it is an assistant that works alongside your keyboard, so you can keep Gboard or SwiftKey for typing. On iPhone, check the keyboard's supported features. We have not established a universal writing-quality winner through comparative testing.
Does Grammarly Keyboard execute tasks?
No. Grammarly Keyboard focuses entirely on improving text quality — grammar, tone, clarity, and style. It does not search the web, book reservations, share locations, or run cross-app workflows. It is an AI keyboard (writing-first), not an agentic keyboard.
What needs Grammarly Pro or cloud processing?
Basic grammar and spelling checks are available for free. More advanced writing suggestions, rewrites, tone, and clarity tools may require a paid Grammarly plan depending on platform and rollout. Advanced checks can use cloud processing, so review Grammarly's current privacy and plan details before using it for sensitive work text.

Free core suggestions and paid features have different limits, so check the plan and platform details for the tools you need.
