The 4-Part Brief That Makes
AI Write Like You.
BRAND. AVOID. TONE. PLATFORM. Four inputs that turn generic AI output into content that sounds exactly like you.
Notion AI
Paste your voice brief directly — it follows instructions better than any generic prompt.
"You are a content writer for [BRAND]. Avoid: [AVOID]. Tone: [TONE]. Platform: [PLATFORM]. Write [content request]. Output only the final copy."
The difference isn't the model. It's the brief. One well-structured brief = consistent, on-brand output every single time.
