Writing Assist

Why It Exists

Users need to write clearly and effectively without manual proofreading, grammar checking apps, or professional editing services.

How It Works

Galaxy Writing Assist is Samsung's AI-powered writing enhancement tool that provides real-time grammar correction, style suggestions, and content rewriting. Using on-device NPU models and Samsung Cloud, it can adjust tone, simplify complex sentences, expand brief notes, and translate writing style. The system integrates into the Samsung Keyboard and Samsung Notes, providing writing assistance across all apps.

Everyday Use Cases

• Grammar correction
• Tone adjustment
• Sentence simplification
• Content expansion
• Style matching
• Professional writing enhancement

User Workflow

• User types or pastes text in any supported app
• Writing Assist analyzes grammar and style in real-time
• Suggestions are shown as underlined words or phrases
• User accepts or ignores suggestions
• Rewritten text is applied to the input

AI Processing Flow

Text is analyzed by on-device NPU language models for grammar, spelling, and style. The system maintains context across sentences and paragraphs. Tone adjustment and rewriting use cloud-based LLMs with encryption for complex transformations. Samsung Cloud syncs writing preferences across devices. All text stays encrypted and is not stored beyond processing.
