Short answerFor internal use you do not need a public page, so workspace tools fit: OpenAI plugins, Claude Projects shared on Team and Enterprise, Copilot Studio inside Microsoft 365, Gemini Gems in Workspace (transitioning to skills) or a self-hosted chat UI.
| Option | Sharing model | Watch out for |
|---|---|---|
| OpenAI plugin | Share with people or groups who install it | Rebuild Actions; permissions |
| Claude Projects | Team and Enterprise: share with members, view or edit | No public sharing; no Actions verified |
| Copilot Studio | Publish to Teams, SharePoint and other channels with Microsoft authentication | Billing in Copilot Credits; trial cannot publish |
| Gemini Gems | Viewer or editor access; admins can disable sharing | Gems are transitioning to skills |
| Open WebUI or LibreChat | Users, groups or roles | You run the server; license notes |
