@ in the prompt box or a Preview Agent message to open the same reference menu in both places.
What you can reference
- Recently used: your last few references, for quick reuse.
- Characters, Locations, Props: your library by category, each showing its item count. Type after
@to search by name, or click a category to browse directly. An item with multiple variations or images shows a count; click through to pick one instead of the default. Only files saved to your project library show up here: save a Character, Location, or Prop first, then reference it by name. - Gen History: every file generated in this story. Search by description (subject, color, style), not just exact name.
- Uploads: project files outside any library category.

After you pick
The reference appears as a chip in your text. Right-click it to Locate on canvas (when it’s placed there), Replace with something else, or Remove.
The prompt box also has Click to pick, to reference directly from the canvas instead of the menu; it enforces each model’s reference limit too. Preview Agent’s chat has a simpler + attach button (Assets, Characters, Locations, Props, Upload) as a flatter alternative alongside the same
@ menu.
