Google or Microsoft for an AI assistant that answers from your own documents? We tried both
Clients keep asking for AI assistants that answer from their own documents, a technique known as retrieval-augmented generation. From December into January our R&D team tried Google Gemini, Microsoft Copilot Studio and Azure AI Foundry hands-on, then wrote up what we found. For firms already on Microsoft 365 we lean to Copilot Studio, which is mostly no-code, and to Azure AI Foundry when the assistant needs to complete tasks, not just answer. Most firms should start from the suite they already pay for.
