OpenAI announced at its recent Dev Day presentation that ChatGPT plugins now support app-like interfaces and automated workflows. Developers can build dedicated experiences within the ChatGPT sidebar, featuring interactive panels and file viewers that function alongside the chat interface. The company has also introduced a new Plugin Creator tool to simplify development and updated the directory submission process to provide clearer feedback. Additionally, ChatGPT Sites can now host these plugins, allowing users to share custom applications with colleagues while maintaining separate data permissions. Support for the proposed MCP Events specification enables plugins to trigger automations based on events in connected applications.
This update shifts ChatGPT from a standalone assistant toward a central hub for integrated work tools. By moving plugins into a sidebar and allowing them to host their own interfaces, OpenAI reduces the friction of switching between applications. The ability to approve access needs individually adds a layer of security control for users. These changes aim to make the plugin ecosystem more accessible for developers while giving end users more granular control over how external tools interact with the chatbot.
* Plugins now occupy a dedicated home in the ChatGPT sidebar.
* Developers can create custom file viewers for supported formats.
* MCP Events support allows plugins to trigger automations based on external app activity.
