The Easiest Way to Use AI In Your Business

I’ve built tech startups from scratch and bootstrapped them to $80,000/month in revenue. And if there’s one thing that gave me an unfair advantage in recent years—it’s this: The easiest, fastest, and most powerful way to use AI in your business today is through Custom GPTs.

You don’t need to code. You don’t need to hire an engineer. These are no-code AI tools that can think like you, scale your brain, and work 24/7 with zero complaints. They can handle repetitive tasks, train your team, write content, answer questions—anything.

Let me show you how it works, how I’ve used it inside my businesses, and how you can get one running today—even if you’re not technical.

Why You Should Stop Using One-Time Prompts

When most people think of AI, they imagine typing a question into ChatGPT and getting an answer. It’s useful, sure—but it’s also limited.

Think of it like hiring a super smart intern… and then making them forget everything after each task. That’s what one-time prompts do—they treat AI like a temporary assistant instead of a long-term teammate.

Now imagine that intern had a brain filled with your company’s tone of voice, documents, SOPs, and customer context—and they never forget anything. That’s what a Custom GPT does.

It allows you to save time, reduce distractions, and eliminate the constant context switching that slows down your team. Instead of searching through Notion or Slack, your team can ask the AI—and it will respond instantly, with the right info, in your brand voice.

What Is a Custom GPT? (Explained Like You’re 5)

A Custom GPT is like your own personal version of ChatGPT, trained specifically for your business.

And no—you don’t need to be technical to build one. All you need is a ChatGPT Plus account. Once you’re in, just click on “Explore GPTs,” hit “Create,” and start giving it instructions.

You can tell it how to behave (friendly, formal, concise, etc.) and upload documents you want it to learn from—like SOPs, sales scripts, onboarding guides, and more.

Think of it as hiring an intern that never sleeps, doesn’t get tired, and already knows everything about your business. You can even teach it things like your favorite books or frameworks, and it will start thinking the way you do.

How I Use Custom GPTs in My Own Business

Here’s where it gets real. These aren’t just ideas—we actively use Custom GPTs inside my companies. Let me break down three actual examples.

1. Content Repurposing Assistant

At Sigma School, we produce content across YouTube, LinkedIn, TikTok, and more. But repurposing long-form content into short posts was eating up hours every week. So we trained a GPT on our tone of voice, past content, and high-performing hooks.

Now, we just drop in a podcast transcript, and the GPT gives us 5 viral hooks, 3 Twitter threads, a LinkedIn carousel script, and even summary ideas—all within minutes. What used to take 2 hours now takes 2 minutes.

2. Admissions Training GPT

For our bootcamp admissions team, we needed a better way to onboard new team members and help them respond to leads. So we trained a GPT using our CRM responses, objection-handling scripts, and bootcamp curriculum.

Now, a new team member can ask, “How do I respond when someone says the course is too expensive?”—and the GPT gives them a detailed, contextual, high-converting response, just like our top closers.

3. Internal SOP Search Assistant

Most teams store their SOPs in Notion—but no one wants to search through pages of documents. So we uploaded all our SOPs into a Custom GPT and made it searchable.

Now, team members just ask, “How do I submit an expense?” or “What’s the refund policy?”—and they get answers immediately, complete with links and steps. It’s like a company wiki that talks back.

This Isn’t Just Me—Here’s a Wild Story

A friend of mine took this idea to the next level. He uploaded the entire book Never Split The Difference—a top-tier sales negotiation book—into a Custom GPT. Then he told it to act like a hard-to-close customer so he could practice his pitch.

He ran simulation after simulation. No roleplays, no coach—just AI giving him feedback. Within 30 days, he closed more deals than he had in the previous 6 months. That’s the kind of growth Custom GPTs unlock—they let you train in real-world conditions with zero risk.

How You Can Build Your Own Custom GPT (Step-by-Step)

To get started with your own Custom GPT, the first step is to subscribe to ChatGPT Plus, which costs about $20 a month. It’s a small investment for a massive productivity boost.

Once you’re in, head over to the left sidebar and click on “Explore GPTs.” Then, hit “Create GPT” to begin building your custom AI. You’ll be asked to provide instructions that tell the GPT how to behave.

For example, you might write something like: “You are a helpful assistant trained to help with [X]. Use a friendly, concise tone. Only respond if you’re 100% sure. If not, ask for clarification.”

Next comes the magic—upload the documents that contain the knowledge your GPT needs, such as PDFs, Word files, spreadsheets, or any internal resources. The more specific and relevant the material, the better your GPT will perform.

Finally, test it out with real questions and tasks. Observe how it responds and fine-tune the instructions until it gives consistent, helpful answers. Within just 30 minutes, you’ll have a powerful AI assistant customized for your business.

Bonus: Advanced Use Cases (If You’re Nerdy)

If you want to go beyond the basics, you can connect your GPT with other tools to make it even more powerful.

You can integrate it with Zapier to automate tasks. You can link it to your Google Drive to pull in real-time documents. You can even give it a voice using tools like ElevenLabs, and have it talk back to you.

Some people are taking Custom GPTs to the next level by integrating them into their daily workflows in powerful ways.

For example, some have set up their GPTs to monitor internal Slack channels, allowing the AI to answer team questions instantly and reduce the need for constant human intervention.

Others use Custom GPTs to generate job descriptions on the fly, tailoring them to specific roles, departments, or skill sets with just a few prompts.

There are even teams who train their GPTs to conduct mock interviews, providing realistic questions and giving detailed feedback—making it an incredibly useful tool for both interview practice and recruitment training.

These advanced use cases show just how versatile and impactful Custom GPTs can be once you move beyond the basics.The potential is endless. But don’t feel pressured to do everything at once. Start with one use case. Build momentum.

Why This Matters

AI is leverage. That’s it.

You can either keep spending hours doing repetitive work—or you can spend 30 minutes creating a tool that handles it for you, every day, forever.

The moment I started treating AI like a smart employee—not just a fancy toy—everything changed. My team became more productive, my calendar opened up, and I got my focus back. And that all started with building one simple Custom GPT.

What You Should Do Next

If you’re a founder, freelancer, or solo creator, your time is your most valuable asset—so it’s crucial to protect it and find ways to multiply it.

One of the most effective ways to do that right now is by using AI to extend your brain. Building just one Custom GPT this week could make a significant impact.

Whether it’s a sales assistant that helps handle objections, a content writer that repurposes your material, a team trainer that onboards new hires, or a customer support bot that answers common questions, the benefits are immediate.

Even if you start small—like uploading your FAQ to create a simple help assistant—you’ll quickly see how powerful and time-saving this tool can be. The key is just to take that first step.
