Get Your Money's Worth from Custom GPTs 2026 Guide
Custom GPTs are one of ChatGPT's most underutilized features, and they can drive real traffic into your business. In this walkthrough I build a business assistant Custom GPT live: it showcases my services, answers questions from a document I provide, and pushes people to book a meeting with me. You will see the whole flow, from the GPT Store to publishing and testing your own assistant.
What you need
- A paid ChatGPT subscription, twenty dollars per month, to create Custom GPTs; using other people's GPTs is free
- A text document describing your services or expertise
- A booking link, for example from Cal.com, if you want meetings on autopilot
1. Why Custom GPTs matter (0:00)
A Custom GPT is a fantastic way to leverage the years of knowledge you have in your area of expertise and put yourself out there. As an individual or a business you can create assistants for your employees, coaches for yourself in areas you want to improve, or a public assistant that links back to your company so people can contact you. In other words, you can drive website traffic to your own business through the GPT feature.
2. Exploring the GPT Store (0:47)
From the ChatGPT homepage, click the GPT section, then Explore GPTs. This is the GPT Store, where you browse all the public Custom GPTs, one for literally every use case out there.
Type the keyword "law" and look at the numbers. The first result, Legal and Contracts, Lawyer Beck, has three million conversations. The second has two million. The third, nine hundred thousand. One individual created a Custom GPT just to cartoonize images in a Ghibli style and got over a hundred thousand conversations. That is what leveraging your expertise looks like: build a knowledge base, put it out there, and anyone can use it without paying more than their twenty dollars a month. Insane returns.
3. Creating your first Custom GPT (2:10)
Click the Create button at the top right. You land on a window full of fields, but do not worry: we will create everything with natural language. You can also choose the model your Custom GPT runs on. This is honestly optional; I would recommend 4o if you want something more creative, and GPT 5.2 Auto is perfectly fine.
4. Configuring your business assistant (3:26)
My use case: I have a document explaining all the services in my company, with case studies for each service, and I want people to book more meetings with me. So I talk to the builder:
Hey, so I want to create an assistant that is going to showcase all of
the services that I have inside of my company. I'm gonna give you a text
document containing all of the necessary information. If someone asks you
questions regarding what my business does, then you are simply going to
reply with information in that document. Then after you send the message
to the person, you will always ask them to book a meeting with me, and I
will give you the link for that right now.
I paste my calendar link and hit Send. Creation takes about thirty seconds to a minute depending on the model, since GPT 5.2 has reasoning capabilities and can be slower. A little wrench icon appears saying the Custom GPT is updating.
5. Conversation starters, name and logo (4:52)
The builder names it Company Services Assistant; I rename it Genial Assistant after my business. It generates four buttons, the conversation starters: pre-written prompts a visitor can click to kick off the chat, which lets you put a small bias on what you want people to ask about, like white label services or marketing campaigns. It also generates a logo, and you can feed it images or brand guidelines instead. When it asks how the assistant should operate, I answer warm, and you keep refining in natural language.
6. Configuration deep dive (5:58)
Hit the Configure tab to fine-tune everything by hand. All the instructions I dictated are there. The conversation starters are editable: add a fifth, or delete one you do not like, as I did to get down to three. The really fantastic part is the knowledge section: I upload the text document with all the information about my business, and it gets loaded inside the brain of this Custom GPT. You can also change the recommended model here.
7. Capabilities, actions and privacy (6:51)
The capabilities toggles matter more than they look. I highly recommend turning off everything the user will not need. Why? If I leave web search on and someone asks what services Genial offers, the GPT will sometimes search the web instead of just looking inside my document, which is wrong. So I turn everything off here.
Actions are more complex: they connect your Custom GPT to another piece of software out there, which opens up a huge number of use cases. That will be the theme of another video. And in additional settings, OpenAI tries to collect data from conversations with your Custom GPT; if people will be having private conversations with it, turn that off.
8. Publishing to the GPT Store and testing live (8:06)
Click Create and choose the visibility: everyone, the GPT Store, or only me. To be visible in the store, select that option, set your author name, and save. My Custom GPT is now out there with all the knowledge of my business, and my LinkedIn attached so people can reach out.
I test it live: "What services does Genial offer?" It answers from its brain with my three core services, AI upskilling, AI consulting, and AI implementation, and then drops the booking link so you can book a call with me. And remember, the public assistant is just the tip of the iceberg: there is an enormous amount of internal use cases, from data analysis assistants to a YouTube video performance analyst.
Pitfalls and tips
- Turn off unneeded capabilities. Web search left on will pull wrong answers from the internet instead of your document.
- Disable the training data collection setting if your users will share anything private.
- Do not skip the conversation starters: they steer the first click toward the services you actually want to sell.
- Creating GPTs requires the paid plan, but your audience uses them at no extra cost, which is what makes the store such a traffic channel.
