How to Train Claude on Your Brand Voice (So It Actually Sounds Like You)

If your AI content sounds off, this is probably why.

You didn’t do anything wrong.

You just didn’t give it enough to work with.

When you ask Claude to write something without context, it defaults to a generic style.

You’ve seen it:

  • slightly formal
  • a little stiff
  • kind of repetitive
  • technically fine, but not you

That’s not because it can’t sound like you.

It’s because you didn’t train it too.

What “Training Your Voice” Actually Means

You’re not teaching Claude how to write.

You’re teaching it how you write.

Your tone.
Your structure.
Your patterns.

And the more clearly you show that, the better it gets.

This takes about 20 minutes to set up if you do it right.

You'll do this inside a Claude Project, which keeps all your context in one place.

Step 1: Gather your best content (not just any content)

This is where most people rush.

They grab whatever is easiest.

Don’t do that.

You want 5 to 10 pieces of content that actually sound like you on a good day.

That could be:

  • blog posts
  • emails
  • sales pages
  • social posts (put them into a doc if needed)

What you don’t want:

  • content written in someone else’s voice
  • old content that doesn’t match how you write now
  • anything that feels forced

This is the reference Claude will learn from.

So it matters.

Step 2: Create a Project specifically for writing

Open Claude.

Create a new Project.

Name it something simple like:
Content Writing

Upload your examples.

Now Claude has something to study.

Step 3: Write instructions that actually define your voice

This is the part most people keep too vague.

If you say:
“write in a casual tone”

That could mean 50 different things.

Instead, get specific.

You can structure it like this:

"You are a content writer for [your business].

Write in a conversational, direct tone.

Voice characteristics:

  • sentence length: short to medium, easy to read
  • vocabulary: simple, clear, no unnecessary jargon
  • perspective: mostly second person
  • tone: approachable with a bit of edge

Avoid:

  • corporate language
  • buzzwords
  • overly polished phrasing

Structure preferences:

  • paragraphs over long lists unless needed
  • clear subheads
  • examples where helpful

If something is unclear, ask before writing.

The more specific you are, the better the output.

Step 4: Test and Refine

Now you test it with a real task.

Example:

Write a 300 word email about why most AI content sounds the same and how to fix it.

Then read it like you would your own content.

Ask yourself:

  • does this sound like me
  • what feels off
  • where does it lose my voice

Then go back and adjust your instructions.

Test again.

You usually need 2 to 3 rounds to get it dialed in.

Common Mistakes to Avoid

Being Too Vague

Casual, professional, friendly… none of those mean much on their own.

Spell it out.

Mixing Different Writing Styles

If your examples don’t match each other, Claude won’t know which direction to follow.

Pick content that feels consistent.

Expecting It to Be Perfect

It won’t be 100 percent you.

That’s not the goal.

The goal is getting closer so you spend less time rewriting.

What to Expect Once It’s Set Up

When this is done right, you’ll notice:

  • sentence structure feels more like yours
  • word choice sounds more natural
  • tone stays consistent across longer pieces

You’ll still edit.

But you won’t feel like you’re starting from scratch every time.

How to Keep Improving It

This isn’t a one time setup.

As your voice evolves, your Project should too.

Every time you create something you really like, add it.

Update your instructions when needed.

The more examples you give it, the better it gets.

And once your voice is dialed in, there are a lot more ways to use Claude in your business beyond just writing.

Final Takeaway

If you want Claude to sound like you, you have to show it what that looks like.

Clear examples.
Clear instructions.
A little bit of testing.

That’s it.

Next step: turn it into a Claude Skill

Once this is working, the next step is a Claude Skill: a saved set of instructions Claude pulls in automatically whenever that task comes up, in any chat, without you re-explaining it. Skills are what we build most inside Her AI Club, and members get a library of ready-made ones to start from.
