Microsoft 365 Admin Setup - GC AI

If your company requires IT administrator approval for Microsoft 365 add-ins, such as the GC AI add-in for Microsoft Word, please refer to Microsoft’s guide, Manage deployment of Microsoft 365 add-ins, for instructions. To ensure you can use GC AI seamlessly within Microsoft Word, your IT admin may need to manage the deployment of the add-in.

Architecture & Security

GC AI for Word is an OfficeJS web add-in. It runs as a sandboxed web application inside Microsoft Word’s add-in iframe — it is not a COM or VSTO add-in. This means:

No native executables are installed on end-user machines.
No registry modifications.
All code runs within the browser-based OfficeJS runtime and is subject to Microsoft’s add-in security model.

For a comprehensive overview of our security posture, data handling practices, and compliance certifications, visit the GC AI Trust Center.

Network Security Considerations

If you’re experiencing a white screen after installing the add-in, your organization’s network security platform (such as Netskope, Zscaler, or similar web filtering software) may be blocking required connections. See our Troubleshooting Guide for detailed configuration steps.
