Quick answers about Grammarly Keyboard
Is Grammarly Keyboard the best for writing?
For grammar, tone, and clarity checking on mobile, Grammarly Keyboard is one of the strongest writing-focused keyboards. It works inside everyday apps — email, Slack, messages, documents — and catches writing issues that basic autocorrect often misses. However, it is not designed for fast swipe typing or voice dictation as primary features.
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 Premium 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.
