How to Restrict AI Tool Access to Specific SharePoint Sites?

When you purchase a Microsoft 365 Copilot license, you'll receive SharePoint Advanced Management which includes an option to toggle Copilot access for specific sites. Also, you can manage which features of Copilot are available when assigning licenses. It's a comprehensive process that requires time and effort, so be prepared for some trial and error over the next few months. I don't have direct experience with ChatGPT Enterprise, but I'd suggest sticking with Copilot since it's deeply integrated into the Microsoft ecosystem. Once you configure data classification using Purview, you can create stricter access policies.

ChatGPT Enterprise doesn’t use your data for training public models, which is a plus. If you set up SAML & SCIM, you can ensure everything stays secure.

Yes, you can definitely restrict access for both tools! Currently, ChatGPT is easier for limiting access for your specific needs. It's a good start for ensuring data security while using these tools.
