Ask Copilot about selected PowerPoint Live text

Before you start

Microsoft lists this attendee feature for Windows under roadmap 557256. The presenter must share through PowerPoint Live. Ordinary screen sharing does not provide the same selectable slide content. Check Copilot access with your organisation.

Try the documented interaction

1. Join a meeting as an attendee in Teams on Windows.
2. Wait for a presentation shared through PowerPoint Live.
3. Select a short piece of slide text.
4. Use the available Copilot explanation interaction for the selection.
5. Read the explanation in the side pane.

Try one unfamiliar term

Select an acronym you do not recognise. Check whether the explanation fits the sentence on the slide. If several meanings are possible, ask the presenter which one applies.

If the interaction is missing

Check that you are an attendee, the presentation uses PowerPoint Live and you are on the documented Windows platform. Ask IT about Copilot access and rollout. Request the term’s meaning in meeting chat as a fallback.

Availability and limits

The release notes confirm selected-text explanations but do not establish one universal button label or support on every device. This guide therefore does not promise an “Explain this” button. An explanation may miss the speaker’s intended meaning and does not make a chart accessible by itself.
