What Are ChatGPT Plugins?

A ChatGPT plugin is an extension that allows ChatGPT to communicate with external software, websites, APIs, cloud services, and business applications.

Instead of only generating text from its built-in knowledge, ChatGPT can:

• Read files
• Search external data
• Access cloud storage
• Read emails
• Manage calendars
• Connect to databases
• Control third-party software
• Retrieve live information
• Automate repetitive work

Think of plugins as "skills" that give ChatGPT additional abilities.
