For the majority of enterprises already on M365, it's the default that keeps getting harder to beat — native Graph grounding across SharePoint/Teams/Outlook with tenant-level permission fidelity, Copilot connectors for third-party sources, and no new vendor or security review needed; ranked #2 on the assumption the typical buyer is M365-centric.
Grok Unmatched integration and permissions inheritance across SharePoint/Teams/Outlook/Dynamics for MS-centric orgs; rapid deployment, hybrid retrieval + LLM, scales massively with existing investments.
GPT Compelling value for Microsoft-centric companies because it searches Microsoft 365 and connected external content while retaining source permissions and supplying grounded, cited answers inside familiar workflows.
Where Microsoft 365 Copilot falls short, per the models
- GPT Licensing and ecosystem dependence make it a weaker neutral search layer for organizations whose knowledge primarily lives outside Microsoft 365.
- Claude Mediocre outside the Microsoft estate — third-party connector quality and ranking lag Glean badly, so heterogeneous stacks (heavy Slack/Notion/Google) get second-class results.
- Grok Weaker outside Microsoft stack; less flexible for heterogeneous/non-MS data sources.
