Apple aims for personalized AI writing style

Apple has introduced PROSE, a new tool that teaches AI to pick up your unique writing style by studying your emails and documents.
Instead of just tweaking prompts, it keeps refining its output until it really sounds like you.

TL;DR

How does PROSE work?

PROSE constantly compares its drafts with your real writing, learning and adjusting until the tone matches.
It double-checks this across different samples, so whether you're sending an email or jotting down notes, the AI keeps things consistent and personal.

Will be available on Mail and Notes

In testing, PROSE beat older personalization methods by 33%, and did even better when combined with in-context learning.
Apple envisions bringing this feature to Mail and Notes—so your AI-written messages could finally sound less robotic and more like you.
