Microsoft Copilot and Perplexity both access external data to answer questions, but the data they access is completely different. Copilot taps into your organization's Microsoft 365 data — emails, files, meetings, and chats via Microsoft Graph. Perplexity searches the open web and delivers cited answers from public sources.
This means they solve different problems and require different prompting strategies. Copilot prompts should reference your organizational data. Perplexity prompts should be focused research questions targeting web sources. Here's how to use each effectively.
