Begin with your profile
Describe specific writing habits in Tone and Principles: sentence length, formality, words to avoid, and how you treat uncertainty. “Short paragraphs, concrete examples, no hype” gives more direction than “sound like me.” Save the profile with public-use confirmation.
Improve a draft
Request one or two targeted changes in Chat, or edit the draft yourself. Saving an owner edit can suggest a private style memory candidate. Review it separately in Brain; confirming a draft is not confirming a style lesson.
Keep style and stance separate
A style example shows how something is written, not that you believe every claim it contains. Outside writing and AI suggestions keep their origin. Public positions must come from your explicitly saved profile or confirmed eligible position memories.
Current limits
The current source form does not offer a dedicated owner-writing-sample declaration. You can still personalize through profile fields and explicitly confirmed style memories. Private samples or memories must not shape public drafts. Inspect the result yourself; style guidance is not a guarantee of a perfect imitation.
