Your AI Doesn't Know Who You're Talking To (Build a Customer Profile in 2026)

Your AI has no idea who it's talking to, because nobody ever told it who to aim at. So it writes for everybody at once, and what comes back sounds fine but it lands on nobody.

This is the twin of the voice profile problem, just one step further out. Voice is how you sound. The customer profile is who you're aiming that sound at.

Why It Comes Out Flat

AI is a great tool, but writing is still where it hits the most walls. Ask it for a post about what you do and it hands back something so general you could paste it on a competitor's site and nobody would notice.

That's not the model being bad. It's a lack of context, because you never gave it a real person to write to. Here's what it's guessing at every single time:

• Who they are - the job they hold and the mess they were sitting in when they found you
• What it was costing them - in hours or dollars or the same fight every week
• What they wanted instead - in their words and not your marketing words
• What made them say yes - because that one line is your best headline

Take these two lines for an HVAC company and tell me which one you'd stop scrolling for.

The first one talks to everybody and lands on no one. That gap is the whole difference between pulling leads in and watching them go somewhere more specific.

The Fix Is One Real Conversation

Everything the model is missing already exists, because you've already had the conversation you need. So don't describe your customer from memory. Go pull a real back and forth with a client out of your email or your DMs.

You can widen that net too, since Claude and Codex will read every post and newsletter you've shipped and tell you who keeps showing up. Then paste the thread in and let it interview you about that one person, one question at a time.

The goal is a profile you keep and reuse. Not a nice answer you read once and lose. Without some kind of knowledge base under it, you can't expect the AI to write better tomorrow than it did today.

• Let it ask instead of assuming - so the profile comes out of your own answers
• Keep it where your agents can read it - because that's what makes it pay off twice
• Pair it with your voice profile - together they cover how you sound and who you're talking to

This is the same move as the knowledge base that updates itself. One place your agents read from, so the whole team gets sharper at once.

Narrowing Down Is Not Shrinking

Narrowing your reach feels like shrinking the pond, so most people never do it. But if you're talking to everyone then you're talking to no one, and the middle of the road is where copy goes to die.

Narrowing down isn't a risk. The people you lose were never buying anyway.

• You write faster - because you stop hedging for readers who were never going to buy
• The right people spot themselves - so they reply instead of scrolling past
• Your AI gets sharper too - since a narrow target is a much clearer order than a wide one

One Thing to Try This Week

Find one real client thread and turn it into a profile. It takes an afternoon at most.

• Pull the thread - open your email or your DMs and find a real back and forth with a client, not a form
• Let Claude interview you - paste the whole thing in and answer one question at a time
• Write to that one person - and nobody else, then watch how fast it comes together

If you'd rather not start from a blank page, I put my whole setup for this into a Notion template, with the same questions Claude asks and somewhere to keep the answers so your AI can read them later.

Before You Go

We go through this properly inside TheVibeStack: Claude/Marketing, right after the voice profile, because the two of them together are what make everything else you build sound like you.

So if you'd rather build it with some help than piece it together alone, that's the place to do it.
