it works equally well whether your stack is Microsoft, Google, or neither, which is the assumption behind ranking it above the suite vendors.","fix":"Expensive per-seat pricing and enterprise-sales-only motion put it out of reach for small teams; you're also handing an index of everything to a third-party cloud."},{"rank":2,"product":"Microsoft 365 Copilot","reason":"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;

committing means betting Google sustains an enterprise product long-term."},{"rank":4,"product":"Onyx","reason":"The strongest open-source answer (formerly Danswer) — self-hosted connectors to 40+ tools, document-level permission syncing, model-agnostic RAG (point it at any LLM including local ones), free to run;

it uniquely spans employee, support, and customer-facing search from one index, and its usage analytics for knowledge-gap detection are best in class.","fix":"Aging platform ergonomics and services-heavy implementations;
