This is the setup that changes everything. Once Claude can read your Notion workspace, it stops guessing and starts pulling from real data.

How to set it up (takes 5 minutes):

1. Open Claude → Go to Settings → Integrations
2. Click "Connect Notion" → Grant access to the specific pages Claude needs (your ICP file, voice guide, and case study doc)
3. Test it — Start a new conversation and say: "Read my Master ICP File in Notion. What are the top 3 pain points my ideal client has?" If Claude pulls accurate info from your doc, you're connected.

How to use it in every prompt:

Start every prompt with a reference to your Notion docs. This is the key habit.

Instead of this:

"Write a LinkedIn post about why coaches need to be visible online."

Do this:

"Read my Master ICP File and Voice Guide in Notion. Write a LinkedIn post that speaks to the exact pain point my best clients had before working with me — the referral ceiling. Use a specific example from my case study bank. Match my tone and sentence rhythm from my style guide. No corporate jargon. End with a CTA that invites DMs."

The first prompt gives you generic content. The second gives you content that sounds like it was written about one specific person — because it was.

Pro tip: Use Claude Projects

Claude has a Projects feature. Create one called "LinkedIn Content" and upload your ICP doc, voice guide, and case studies as project files. Set custom instructions that apply to every conversation in that project.

This means you don't have to reference your docs every single time. Claude already has the context loaded when you start a new conversation inside that project.
