Microsoft offers a growing range of AI tools, but many businesses struggle to know which one they actually need. Terms like Copilot, Agentic AI, Copilot Studio, and MCP are often used interchangeably, even though they serve very different purposes. Choosing the wrong tool can lead to unnecessary costs and complexity. The key is to start with the simplest solution that meets your needs, then move to more advanced tools only as your business grows.
