Before you start
Add your video to the card library to create a video card.
Generate a transcript for that video card.
The AI uses the transcript as context (it doesn’t read the raw video).
Start a chat with a video card
From a whiteboard: Right-click the video card and choose New chat / Add to chat (top option).
From Chat: Click the + button at the top-left and select the video card you want, or @mention that video card directly.
Not supported yet
Mentioning a card does not make the AI read any videos embedded inside that card.
You can’t insert or embed a standalone video in a chat and have the AI read it as context.
