Reading through the news coming out of Microsoft Ignite:
Microsoft 365 Copilot will feature dedicated Word, Excel and PowerPoint Agents — available through the Frontier program — that can create high-quality Office content directly from Microsoft 365 Copilot Chat. Simply type a prompt, and these agents will ask targeted follow-up questions to tailor the output to a user’s goals in creating documents, spreadsheets and presentations. The agents will be able to handle tasks like research, formatting and layout design.
This will allow the user to create a torrent of new documents. But it also provides help so you don’t need to read all the documents your coworkers create:
Copilot Chat in Outlook will be content aware across a user’s entire inbox, calendar and meetings, instead of only individual email threads. Users will be able to triage their inbox, schedule and prepare for upcoming meetings, and surface insights and actions across their inbox and calendar to stay ahead.
I have seen this before:
