I keep having the same conversation with different companies, and it goes something like this:
"We want to build custom GPTs for our team. We want AI agents that can write in our brand voice, understand our audience, and produce content that actually sounds like us. Can you help?"
"Absolutely. Let's start by looking at your brand guidelines, writing style guide, and audience segmentation documents."
Long pause.
"We... don't really have those documented."
And that's the problem. Everyone wants the AI capabilities, but almost nobody has the foundational materials you need to actually train the models effectively.
Here's what people don't realize about building custom GPTs or AI agents: They're only as good as what you feed them.
You can't just tell an AI "write like our brand" and expect it to magically understand what that means. You can't say "target our audience" when you've never clearly defined who that audience is or what matters to them.
AI needs structure. It needs examples. It needs rules and guidelines and frameworks to work from.
Think about it this way: If you hired a new content writer tomorrow, what would you give them to get up to speed? Hopefully not just access to your website and a "figure it out" attitude.
You'd give them brand guidelines so they understand your visual identity and tone. You'd give them a writing style guide so they know your preferences for voice, grammar, and formatting. You'd give them audience personas so they understand who they're writing for. You'd give them examples of great content you've created before.
AI needs all the same things. Actually, it needs more because it can't ask clarifying questions or intuit what you mean from context clues the way a human can.
When I audit companies for AI readiness, here's what I'm looking for:
Brand guidelines that go beyond just logo usage and color codes. I need to understand your brand personality, your values, your positioning, how you want to be perceived in the market.
Writing style guides that codify your preferences. Do you use Oxford commas? Do you write in first person or third? What's your stance on contractions, em dashes, sentence fragments? How formal or casual should the tone be?
Audience segmentation documents that clearly define who you're talking to. Not just demographic data, but psychographic information. What do they care about? What keeps them up at night? What language resonates with them?
Service or product descriptions that are accurate and compelling. Not the marketing fluff that lives on your website, but clear explanations of what you actually do and why it matters.
Writing rules and conventions that are specific to your company. Industry terminology you use or avoid. How you refer to your products. Messaging frameworks you've tested and know work.
Maybe one in ten companies has all of this documented. Most have bits and pieces scattered across different people's brains, old presentations, and that brand deck from three years ago that nobody can find anymore.
The collateral gap doesn't just affect your AI strategy. It affects everything.
When your brand guidelines exist only in your marketing director's head, every new hire has to reinvent the wheel. Every vendor you work with interprets your brand differently. Every piece of content drifts a little further from whatever your "brand voice" is supposed to be.
When you don't have documented audience frameworks, your sales team is targeting one persona, your marketing team is targeting another, and your content team is just guessing.
When your service descriptions aren't clearly defined and agreed upon, you get inconsistent messaging across every touchpoint. Your website says one thing, your sales deck says another, your case studies tell a third story.
The lack of documentation creates drift. And drift creates mediocrity.
AI just makes this problem impossible to ignore anymore.
What I've started doing is positioning collateral creation as a prerequisite engagement before any AI implementation work.
We come in and do the excavation work that should have been done years ago but somehow never happened. We interview stakeholders, audit existing materials, analyze competitor positioning, and codify everything into usable documentation.
This typically includes:
A comprehensive brand guide that covers not just visual identity but brand personality, voice, values, and positioning. The kind of document that actually helps people make decisions, not just shows them which shade of blue to use.
A detailed writing style guide with specific rules, examples, and non-examples. "Write conversationally" isn't helpful. "Use contractions, keep sentences under 25 words, write in second person, avoid passive voice" is helpful.
Audience segmentation frameworks that go deep into who you're targeting and why. What their goals are, what their challenges are, what language resonates with them, what turns them off.
Messaging frameworks that articulate your core value propositions, key differentiators, and proof points. The things you say over and over because they're true and they matter.
Content and communication rules that are specific to your business. This might include terminology preferences, compliance requirements, competitive positioning guidelines, or brand-specific conventions.
Once you have all of this documented, training AI becomes straightforward. But more importantly, everything else becomes easier too.
I know what you're thinking: "This sounds like a lot of work for something that should have been done already."
You're right. It is a lot of work. And yes, it should have been done already.
But here's the thing: This isn't just a checkbox you need to complete before you can use AI. This is foundational marketing infrastructure that will make literally everything you do more effective.
When you have clear brand guidelines, your marketing becomes more consistent. When you have documented audience frameworks, your messaging becomes more targeted. When you have codified writing rules, your content quality improves across the board.
And then, as a bonus, you can actually build AI tools that work the way you want them to.
The companies that figure this out first are going to have a massive advantage. Not just because their AI will be better trained, but because they'll have the strategic clarity that most of their competitors are still lacking.
The biggest mistake I see companies make is waiting until they're ready to implement AI before they start thinking about documentation.
By then, it becomes a bottleneck. You're excited about the AI capabilities, you want to get started, and suddenly you have to pause everything to do months of foundational work you didn't know you needed.
Start now. Even if you're not planning to build custom GPTs next quarter. Even if AI isn't at the top of your priority list.
Document your brand guidelines. Write down your style preferences. Define your audience segments clearly. Codify the rules and frameworks that exist in your team's collective knowledge.
Because whether you're training AI or training humans, you need this stuff. And the sooner you have it, the more effective everything else becomes.
