OpenAI replaced the app directory with the plugin directory on July 9, 2026. Plugins are now the main way to add capabilities to ChatGPT. OpenAI’s plugins help article says a plugin can include skills, connected apps, and other parts, and installing one may ask you to sign in to the underlying service.
To add one, open Plugins in the ChatGPT sidebar or go to chatgpt.com/plugins, pick a plugin, review what it can access, and install it. Then mention it with @ in a chat, or just describe the task and let ChatGPT choose. OpenAI’s plugins page says select plugins are available in all plans, including Free, and that some require a paid plan.
We only list plugins we could open in the directory ourselves. Descriptions below come from each listing, and “developer” is as the listing shows it.
