Understanding the ChatGPT Interface
Yes. Since this page is part of your AI Agents Step-by-Step series, I would keep it practical and beginner-friendly. I also checked the current ChatGPT desktop interface because the interface has recently changed: the Windows app now has ChatGPT / Codex at the top level, with Chat / Work inside ChatGPT, and Projects appear in the sidebar.

Here is the complete article you can copy into your WordPress Visual editor.
Understanding the ChatGPT Interface
After installing ChatGPT Desktop, the next step is to understand its interface and learn where the main features are located.
The ChatGPT interface is designed to make it easy to start conversations, organize your work, use Projects, work with files, and access additional tools.
The exact appearance and available features may change over time as OpenAI updates ChatGPT. Some features may also depend on your account and subscription plan.
1. The Main ChatGPT Screen
When you open the ChatGPT desktop application and sign in, you will see the main ChatGPT workspace.
The interface is generally divided into a few important areas:
- Sidebar
- Chat area
- Message box
- Model and tool controls
- Projects
- Recent conversations
The exact location of some controls may change with future updates.
2. The Sidebar
The sidebar is one of the most useful parts of the ChatGPT interface.
It gives you access to your conversations and Projects and helps you organize your work.
Depending on your account and the current version of ChatGPT, you may see items such as:
- New Chat
- Recent conversations
- Projects
- Search
- Other available tools and features
You can use the sidebar to return to an existing conversation instead of starting again from the beginning.
3. Starting a New Chat
To start a new conversation, select New Chat.
A new conversation is useful when you want to work on a different subject without mixing it with an existing conversation.
For example, you could have separate chats for:
- C# programming
- Kubernetes
- AI Agents
- WordPress
- Technical writing
Keeping different subjects in separate conversations makes your work easier to manage.
4. The Chat Area
The main area of the window is where your conversation takes place.
You type your request in the message box and ChatGPT generates a response.
You can continue the same conversation by asking follow-up questions. ChatGPT can use the context of the conversation to understand what you are working on.
For example:
User:
Explain what an AI Agent is.
ChatGPT:
Provides an explanation of AI Agents.
You can then ask:
User:
Give me a simple example.
ChatGPT can continue from the previous discussion instead of requiring you to explain the entire subject again.
5. The Message Box
The message box is where you enter your instructions or questions.
You can use it for many different types of tasks, such as:
- Asking questions
- Writing text
- Programming
- Analyzing information
- Summarizing documents
- Translating text
- Generating ideas
- Working with files
The quality of the result often depends on how clearly you describe what you want.
Instead of writing:
Write something about AI.
A better request would be:
Write a beginner-friendly explanation of AI Agents for software developers, including their architecture, tools, memory, and real-world examples.
The second request gives ChatGPT much more useful context.
6. Chat and Work
In the current ChatGPT desktop application, ChatGPT provides different ways of working.
Chat is designed for quick questions, conversations, brainstorming, and everyday assistance.
Work is designed for longer, multi-step tasks and creating finished deliverables such as documents, spreadsheets, presentations, reports, and other outputs. Availability of Work can depend on your account and is being rolled out to eligible users. (OpenAI Help Center)
For example:
Chat:
Explain how an AI Agent works.
Work:
Research AI Agent architectures, compare the major approaches, and create a technical report with recommendations for a .NET development team.
This distinction is particularly important when learning about AI Agents because Work is designed for more agent-like, multi-step tasks.
7. Projects
Projects are one of the most useful features for long-running work.
A Project is a workspace where you can keep related conversations, files, and instructions together. This helps ChatGPT maintain relevant context while you work on a particular subject. (OpenAI Help Center)
For example, you could create a Project called:
AI Agent Development
Inside the Project, you could keep:
- AI Agent tutorials
- Architecture notes
- Programming discussions
- Source-code files
- Documentation
- Research
- Project instructions
Projects are especially useful when you are working on something over many days or weeks.
8. Adding Files to a Project
Projects can contain reference material such as:
- PDF documents
- Word documents
- Spreadsheets
- Images
- Text
- Other supported files
You can provide these files as context for your work, allowing ChatGPT to use the information when answering questions or performing tasks. (OpenAI Help Center)
For example, in a Project called AI Agent Development, you could upload:
AI-Agent-Architecture.pdf
Then ask:
Explain the architecture described in this document.
This is much more useful than repeatedly uploading the same document in separate conversations.
9. Projects and Context
Projects are particularly useful because they keep related work together.
A Project can contain:
Instructions + Files + Conversations + Context
This makes Projects useful for long-term activities such as:
- Software development
- Research
- Writing a book
- Building an AI Agent
- Managing a business project
- Learning a new technology
Project memory can help ChatGPT stay focused on the conversations and files belonging to that Project. (OpenAI Help Center)
10. ChatGPT and Codex
If you are using the current Windows desktop application, you may also see Codex.
ChatGPT and Codex are separate views in the desktop application.
ChatGPT is intended for general conversations, research, writing, analysis, and other tasks.
Codex is focused on software development. It can work with local files, repositories, terminals, and developer tools. Its conversation history is separate from ChatGPT history. (OpenAI Help Center)
For example, ChatGPT can help you understand:
How does this C# class work?
Codex can be used for more direct software-development work, such as:
Review this repository, find the problem in the authentication code, run the tests, and suggest the required changes.
11. Searching Previous Conversations
As you use ChatGPT more frequently, you will accumulate many conversations.
The search functionality can help you find previous chats, Projects, files, and other content without manually searching through the entire history. (OpenAI Help Center)
This becomes especially useful when you use ChatGPT as a long-term development or research assistant.
12. Working With Files
ChatGPT can work with many types of information provided by the user.
Depending on your available features, you may be able to upload documents, spreadsheets, images, and other files.
For example, you could upload a programming project specification and ask:
Analyze this specification and create a list of the required software components.
Or upload a spreadsheet and ask:
Analyze these sales figures and identify the main trends.
13. Choosing the Right Way to Work
A simple way to think about the current ChatGPT interface is:
Chat
Use it for questions, explanations, brainstorming, and normal conversations.
Work
Use it for longer, multi-step tasks and producing complete deliverables.
Projects
Use them to organize ongoing work, conversations, files, and instructions.
Codex
Use it for software development and working with code, repositories, terminals, and developer tools. (OpenAI Help Center)
14. ChatGPT as Part of AI Agent Development
Understanding the ChatGPT interface is important before starting to build AI Agents.
An AI Agent needs several capabilities, such as:
- A language model
- Instructions
- Context
- Memory
- Tools
- Planning
- The ability to perform actions
ChatGPT provides an environment where you can experiment with many of these concepts.
For example, you can create a Project for your AI Agent development and use it to keep your research, documentation, code, and conversations together.
Later in this series, we will move from using ChatGPT to understanding how developers can actually build AI Agents using programming languages, APIs, frameworks, tools, and external systems.
Practical Example
Suppose you want to build a customer-support AI Agent.
You could create a Project called:
Customer Support AI Agent
Then organize your work inside the Project:
Conversation 1
Define the requirements for the customer-support AI Agent.
Conversation 2
Design the architecture.
Conversation 3
Design the database.
Conversation 4
Create the API.
Conversation 5
Design the AI Agent tools.
Conversation 6
Test the Agent.
You can also add your project documentation and other reference files to the Project.
This approach creates a much more organized development environment than putting every question into one general conversation.
ChatGPT Is More Than a Chatbot
At this point, it is important to remember the distinction discussed in the previous article.
A simple chatbot mainly answers questions and maintains a conversation.
An AI Assistant can help you perform tasks.
An AI Agent can go further by planning and executing multi-step actions using tools and defined permissions.
The ChatGPT interface provides access to different capabilities that can help you explore these concepts, but using ChatGPT does not automatically mean that you have built an AI Agent.
Conclusion
Understanding the ChatGPT interface is an important step before moving into AI Agent development.
The main concepts to remember are:
- Chat is useful for conversations, questions, and quick assistance.
- Work is designed for longer, multi-step tasks and finished deliverables.
- Projects help organize conversations, files, instructions, and context.
- Codex provides a dedicated environment for software development.
- Files and tools can provide additional context and capabilities.
As we continue through this AI Agents Step-by-Step series, we will gradually move from using ChatGPT to understanding how AI Agent systems are designed and built.
In the next post, we will create our first ChatGPT Project and learn how to organize conversations, files, and instructions for a long-running project.
