ChatGPT Plugins, Apps, and Integrations Explained

Introduction

Ask five people what a ChatGPT plugin is, and you may get five different answers. That confusion is fair, since the word has changed meaning more than once since 2023.

This matters because the wrong mental model leads to wasted clicks in a menu that keeps moving. ChatGPT plugins today are not the same feature that launched years ago, and knowing the current setup saves time when you are trying to connect ChatGPT to Gmail, Slack, Canva, or your own company data. This guide breaks down what a plugin includes, how apps and skills fit inside it, and how to actually turn one on.

What ChatGPT Plugins Actually Mean Today

The original ChatGPT plugin system launched in 2023 and was shut down not long after. OpenAI then moved through several names, including GPTs, connectors, and an App Directory.

In July 2026, OpenAI brought the word “plugin” back, but gave it a new job. A plugin is now a packaged bundle that can include one or more parts: an app that connects to an outside service, a skill that gives ChatGPT reusable steps for a task, or an app template that a company sets up for its own systems.

The Plugin Directory replaced the older App Directory. It is the single place inside ChatGPT where you browse everything that extends a normal conversation, whether that is searching your email or generating a design in Canva.

A plugin is the package. Apps, skills, and templates are what is inside it.

Apps: The Building Blocks Inside a Plugin

Apps are the part most people actually use. An app connects ChatGPT to another product, its data, or an action that product can perform.

Common examples include Gmail and Google Drive for searching your own documents, Slack for reading and posting messages, and Canva for generating a design from inside a chat. Depending on the permissions you grant, an app can search connected data, show an interactive card inside the chat, or take an action such as creating a task in another tool.

Apps did not disappear when plugins came back. They still do the actual connecting work. The plugin wrapper just makes an app easier to discover and install as part of a complete workflow.

Why the Distinction Matters

  • An app is the pipe that carries data or actions between ChatGPT and another service.
  • A plugin is the storefront listing that bundles the app with instructions for using it well.
  • You can have an app connected without ever thinking about the plugin that introduced it.

Skills and App Templates

Skills are the second ingredient inside a plugin. A skill gives ChatGPT reusable instructions and steps for completing a specific type of task, without necessarily connecting to an outside service.

Think of a skill as a recipe. It tells ChatGPT how to approach a job, such as reviewing a contract against a standard checklist or formatting a weekly report the same way every time.

App templates are aimed at businesses rather than individuals. A workspace administrator configures a template so that everyone on a team connects to the company’s own systems in a consistent, pre-approved way, instead of each person setting things up from scratch.

Custom Connectors and Developer Mode

Not every tool you want shows up in the Plugin Directory by default. For those cases, ChatGPT offers Developer Mode.

Developer Mode lets you add a custom connector by pasting the address of an MCP server. MCP stands for Model Context Protocol, an open standard that lets an AI assistant talk to outside tools in a consistent way. This is the same underlying standard used by other AI assistants, which is part of why some third-party tools can connect to more than one AI platform using the same server.

This option is aimed at more technical users or small teams building their own workflow, rather than a casual user who just wants to check email inside a chat.

How to Find and Install a Plugin

Getting started with a plugin usually takes just a few steps.

  1. Open ChatGPT and look for the Plugin Directory, usually reachable from the tools menu or your profile settings.
  2. Browse by category, such as productivity, design, or data, or search for the specific service you want, like Notion or Asana.
  3. Select the plugin and connect the underlying app through the login screen it provides, often called OAuth.
  4. Grant only the permissions you are comfortable with. Most apps let you choose between read-only access and access that allows ChatGPT to take action.
  5. Return to your chat and mention the connected service naturally, such as asking ChatGPT to pull your latest Drive file or summarize unread Slack messages.

Workspace administrators managing a business account can control which plugins are available company-wide, and can review each app’s permissions separately from the plugin listing itself.

Key Takeaways

  • Plugins are the umbrella: they bundle apps, skills, and app templates into one discoverable package.
  • Apps do the connecting: they link ChatGPT to services like Gmail, Slack, or Canva.
  • Skills add know-how: they give ChatGPT a repeatable method without necessarily touching outside data.
  • Developer Mode is for builders: it lets technical users add any tool that runs an MCP server.
  • Existing connections are not affected: app connections made before the July 2026 change kept working without any extra setup.

FAQs

Are ChatGPT plugins the same as the ones from 2023?
No, the original 2023 plugin system was shut down, and the current plugin system introduced in July 2026 is a different, more capable design.

Do I need a paid ChatGPT plan to use plugins?
Many apps are available on lower tiers, but the most advanced business and workspace features are generally reserved for paid or enterprise plans.

What is the difference between an app and a connector?
An app is the broader term for any integration, while a connector usually refers specifically to an app built to search and read data such as email or files.

Can I build my own plugin?
Yes, developers can build an app using the Apps SDK or connect a custom tool through Developer Mode using an MCP server address.

Is it safe to connect apps like Gmail or Slack to ChatGPT?
It can be safe when you review the requested permissions carefully and only grant access you are comfortable sharing, since some apps can take actions on your behalf.

Conclusion

ChatGPT plugins have gone through several names, but the current version is more organized than any earlier attempt. Apps handle the actual connections, skills add reusable know-how, and the Plugin Directory brings both together in one place. Once you understand that a plugin is simply the package around these pieces, choosing and connecting the right one becomes a quick task instead of a guessing game.
