📢 Official Microsoft Message Center Announcement
Use OneDrive stored user defined custom skills in PowerPoint Copilot (web)
Message ID: MC1434580
[What and Why:]
PowerPoint Copilot on the web is introducing support for personal, user-defined custom skills stored in OneDrive. Users can upload skill folders containing a SKILL.md file to a designated OneDrive location, and those skills will automatically appear in the Copilot Skills menu within PowerPoint for the web. A new Manage Skills experience will also allow users to enable or disable individual skills directly from the Copilot pane. This enhancement supports personal productivity by enabling users to tailor Copilot to their specific workflows and presentation needs while maintaining control over which skills are available during Copilot interactions.
