Apple builds Grammarly-style keyboard

🔑 Enhanced Key Takeaways

• •The integration is part of Apple's broader 'Apple Intelligence' initiative, leveraging on-device Large Language Models (LLMs) to ensure user data privacy by processing text locally rather than in the cloud.
• •The feature set includes 'Rewrite' tools that allow users to adjust the tone of their text (e.g., professional, concise, or friendly) and 'Proofread' capabilities that provide context-aware suggestions for grammar and sentence structure.
• •Apple is positioning this as a system-wide utility, meaning the keyboard-integrated AI will function across third-party applications, not just native Apple apps like Mail or Notes.

🛠️ Technical Deep Dive

• •Utilizes Apple's proprietary 'Ajax' LLM architecture, optimized for deployment on A-series and M-series silicon with Neural Engine acceleration.
• •Implements a hybrid architecture where simple tasks (spell check) run on-device, while complex, high-compute requests may be offloaded to Apple's Private Cloud Compute (PCC) infrastructure.
• •Uses a transformer-based model fine-tuned on a curated dataset of professional and casual writing styles to minimize latency during real-time typing.
