Prompt Playbook: AI Brand Voice

I know I’ve certainly used AI to help with cards, speeches and other everyday writing I need to do.

This has become the norm. Increasingly so.

Will we forget how to write ourselves? Maybe! There’s a phenomenon in China called 提笔忘字 - basically means “pick up the brush, forget the word”. People now type so much in China (on phones primarily) that handwriting the characters becomes difficult! Something similar may happen with our own writing!

So...should we just not use AI to write? At all? Maybe! That's one approach.

But we are entrepreneurs. We use tools to accelerate ourselves and our customers. And if we're going to use these tools - which let's be honest, we are - we need to use them well.

That means learning how to properly capture and replicate our tone of voice. Whether it's for personal writing or business content, if we're going to leverage AI, let's do it right! Nothing worse than i) losing our ability to write and ii) replacing it with something generic and rubbish! Ha!

And this is exactly what's keeping marketing directors and business owners up at night. They're not debating whether to use AI anymore - they're wrestling with how to use it effectively to maintain a consistent brand voice across hundreds of pieces of internal and external content each month. This opens up opportunities for us!

Let's get started

Understanding Brand Voice

Let's talk about brand voice.

It sounds a bit fancy (probably to allow brand consultants to charge a lot - sorry brand guys!). It's what makes your content distinctly "you", whether that's professional and authoritative, casual and friendly, or anywhere in between.

It's more than just how you write - it's your company's personality coming through in every piece of communication.

For entrepreneurs like us, this matters more than you might think. Every social media post, every newsletter (like this one!), every email to customers - they're all opportunities to reinforce who we are as a brand.

Getting this right consistently is crucial, especially as we scale our content production. I personally use AI to help write thousands of words daily across multiple channels, but it has to sound like me. The systems I'll show you this week are exactly what I use to make that happen.

The Perfect First AI Consulting Project

But here's where it gets really interesting.

This isn't just about our own businesses.

My AI consulting students keep reporting the same thing: brand voice is often the first project clients want to tackle with AI.

Clients want a tool that can write blog articles, social posts, internal comms and match their past work and brand guidelines.

It makes perfect sense - it's tangible, it's valuable, and it shows immediate results.

It’s something that clients know AI can do but don’t necessarily know how to build. AKA: perfect for us to come in and build for them!

Why Traditional Approaches Fail

Now, traditionally, companies try to maintain their brand voice through expensive consultants and lengthy brand guidelines. You know the type - 80-page PDF documents that cost £30,000 and end up gathering digital dust in some shared drive. I was working with a marketing team last month who had exactly this problem. Beautiful brand guide, but ask any team member when they last referenced it? Crickets.

But at the same time companies want to produce written content at scale - it’s the key to content marketing.

And they are very willing to pay for it.

Let's run some real numbers from a modest content calendar

Monthly needs

• 4 blog articles (1500 words each)

• 20 social media posts

Time & Cost

• Writing & tone checking: 35 hours

• Total cost with freelancers/agency: £2,300+

And this is a relatively small content load - many companies produce 3-4x this amount across all their channels!

What if you could go to them with a tool that costs, say, £2000. That can generate new content exactly matching their tone of voice? Yeah…easy sell right there.

Key is that they have existing content. And we use this to replicate their tone of voice. We aren’t starting from scratch. This is key - and the focus of the next Part.

Two Clear Opportunities

This presents two clear opportunities for us

1. Internal Implementation (for your own company)

• Write consistent content at scale

• Maintain your voice across all channels

• Train team members faster

• Reduce editing time massively

• Scale your content without losing your personality (kinda the whole point!)

2. Client Services (for other people’s companies)

• Easy £2,000+ starter projects

• Quick implementation (2-3 hours once you know the system)

• Immediate, demonstrable results

• Natural upsell to larger AI projects

Even if you want to do this mainly for other people I’d highly recommend deploying a system for yourself and own company first. It’s a good way to practice and have a great first case study. Plus…you’ll be selling something you genuinely know how to do which…is normally a good idea!

Why Now?

A year ago I wouldn’t have written this Playbook. It would have been, frankly, useless.

Why now then? Simple: the AI got better. A lot better.

A year ago, our options for replicating our tone of voice were … limited. The models weren't sophisticated enough, and we couldn't effectively use our own data to train them.

Now? We have access to incredibly powerful models AND we can feed them our existing content to capture our unique voice. Meaning it’s the perfect time to deploy a consistent tone of voice system.

What’s to come

Over the next four parts, we're going to build these systems step by step

Part 2: The Content Goldmine How to gather and analyse existing content to capture brand voice DNA

Part 3: Voice DNA Extraction Creating the perfect prompts for voice replication

Part 4: Deployment Options Implementing across different AI platforms (ChatGPT, Claude, custom solutions)

Part 5: Training for Success Building, testing, and refining your voice system

And remember all of this can be deployed for yourself and your own business and then (if you want!) for other businesses for easy consultation gigs.
