[ChatGPT Study Session] What can Custom GPT do? | 5 Possibilities and Beyond-Imagination Use Cases 02/07
Last time, we started with the question "What is Custom GPT?" and gradually unraveled its background.
This time, we will finally dive into the main topic: "So, what can it actually do?"
💡 In a nutshell, what can you do with Custom GPT?
It means "creating your own personalized ChatGPT." That is what it is.
To be a bit more specific,
a specific role (persona)
a fixed tone and phrasing
fixed knowledge or information
and unique usage rules
The essence is that you can create a GPT that remembers these things forever once you set them up.
🧠 How is it different from a regular GPT?
Even with ChatGPT (4o or 5), you can "customize" it to some extent by providing information in the prompt.
However, it can be tedious to input that every time, or it might not be stable unless you repeatedly provide the same information, right?
Custom GPT is designed to permanently remember that "initial information."
To use an analogy,
Regular GPT: a talented part-timer (works when instructed each time, but memory is reset every time)
Custom GPT: a dedicated staff member (already trained and works without needing to be told)
That's what it's like.
🛠️ Main items you can set in Custom GPT
On the actual creation screen, you can set the following items.

Looking at it this way, it feels like character settings + operational manuals + tool environments are all packed inside.
👤 From "Personal Use" to "Team Use"
Custom GPTs can be your personal "favorite GPT," or they can serve as a hub for operational efficiency for teams and projects.
An "Editor-in-Chief GPT" that summarizes reports every time
A "Writer GPT" that assists with drafting blogs and notes
A "Sales Supporter GPT" that creates sales materials based on company introductions
and so on; the greatest appeal might be that you can create GPTs tailored to your own work and life.
✍️ Summary: What you can do ranges from "small automation" to "large-scale personification"
I believe the true value of Custom GPTs is the feeling that
"your own alter ego is always there for you."
That is the kind of sensation you can have.
Next time, we will delve deeper into the question of who are these GPTs for?
In other words, we will discuss what kind of people should use Custom GPTs.
