ChatGPT
OpenAI
OpenAI's assistant, extended through the Plugin Directory, where plugins bundle skills and connected apps built on the Apps SDK.
AI platforms
ChatGPT, Claude and Gemini all connect to external applications, but they organize and govern those connections differently.
ChatGPT uses apps and plugin-based workflows, Claude uses directory connectors, remote MCP connectors and desktop extensions, and Gemini uses Connected Apps such as Google Workspace. The words differ, and so do the administrative surfaces behind them: who may approve a connection, whether approval applies to a whole organization, and what a connection is permitted to read or send.
Compare each platform’s verified relationships, terminology, administrative requirements and capability model before choosing one for a workflow. If you are weighing two platforms against each other rather than browsing, the ChatGPT and Claude integration comparison sets them side by side, and what an AI connector is explains the shared vocabulary first.
| Platform | Current terminology | Verified relationships | Best next step |

| ChatGPT | Apps and plugin-based workflows | 16 | View ChatGPT connectors |
| Claude | Connectors, remote MCP and desktop extensions | 16 | View Claude connectors |
| Gemini | Connected Apps | 16 | View Gemini connectors |
