Most construction businesses run on Microsoft, so Copilot is often the AI you already have. It's more confusing than ChatGPT or Claude, but it makes sense once you treat it as three separate tools.
Chat is for questions and answers. Turn on Work IQ so it can read your SharePoint files, email and Teams, and set up one notebook per project so each chat has the right context. Agents are reusable instruction packs: you open the agent, then tag the project notebook into the chat. That's the reverse of how projects work in Claude or ChatGPT.
Co-work is where Copilot edits files and runs tasks inside a SharePoint project. You can schedule jobs like a daily project update in Teams, load skills and connect other apps. Custom connections usually need your IT admin's approval.
Copilot Studio is for building company tools, like more advanced agents, fixed workflows similar to Zapier, and simple apps. Agents you build there show up in Chat, but I still can't get them to appear in Co-work.
If your company is on Microsoft 365, which of these three do you actually use?
