Review the results
Review the summary Copilot generated. How does it flow? Is it ready to share? Or does it need a little more work?
Often the first response isn't perfect. Artificial intelligence (AI) works best with a little back-and-forth conversation. You can get better results by providing more context and details about what you're after.
Provide more context and details
Include some context and a few details in your prompts to get better results with Copilot. Who's the summary for? Why do you need it? How do you plan to use it? Try using prompts like these:
-
What should business decision makers know about <subject in your document>? Why is it important to understand these things?
-
I need to share the main points of this document with my teammates. Write a few paragraphs that include why these points are important to our company.
Are there any calls to action? What should we do next?
With each prompt, Copilot scans the document again, and then generates a response. You can continue submitting prompts until you're pleased with the results.
Try suggested prompts
Copilot offers suggested prompts to try, too. You can always type your own prompts for Copilot. You can also use suggested prompts. With each response, you'll see one or more suggested prompts. Give one a try and see what happens.
