Every tile on the Canvas is a frame. Frames are what you select, drag, and act on. This page covers the frame kinds, the per-frame action bar that surfaces on selection, and the capabilities you trigger from it: Build and Focus.

​
Frame kinds

The two main kinds are Artifacts (live, app-backed surfaces) and Designs (mockups). The frame’s top-left header shows which kind it is.
Whether a Design frame behaves as a static image or an interactive prototype depends on the Interactive frames capability. When it’s enabled, Design frames respond to clicks and form input like a real page; otherwise they render as a snapshot you can iterate on but not click through.

​
Preview on different devices

See how a design looks on different screen sizes. Ask Agent to show you a mobile, tablet, or desktop version, for example “Show me the mobile version of this page”, and it renders a frame at that size:
  • Mobile: 390 × 844
  • Tablet: 768 × 1024
  • Desktop: 1280 × 720

​
Per-frame action bar

Selecting a frame surfaces an action bar. The actions depend on the frame’s kind.

​
Artifact and Design frames

For Artifact (Website, Slides, etc.) and Design frames, the action bar runs across the top of the frame.

A Design frame's action bar: Build…, Focus, and more options.

The action cluster compresses to icons at narrow widths and reveals labels as the frame gets wider. The full set, in left-to-right order: App frames (Website, Slides, Mobile app) show Focus and more options; Design frames add Build… before them. To branch new directions from a selected frame, follow its suggestions. Selecting a frame also attaches it to the next Agent chat message as a snapshot — see What lives on the canvas.
The action bar respects Read-only mode. When Canvas is locked inside a background-task context, the iteration actions hide and only Focus remains.

​
Media frames

Image, Video, and Vector graphic frames show a small floating action bar above the frame. All three kinds share:
  • Replace media: upload a new file to swap into the frame, keeping its position and size on Canvas.
  • Download: save the media file to your computer.
  • Alt text: add alternative text for accessibility and so Agent has more context when the frame is referenced.

Image frames add two more controls:
  • Crop: trim the image directly on Canvas.
  • Generate video: generate a video clip from the image.

​
Explore new directions

Selecting a frame surfaces suggestions beside it: one-click directions grounded in what you’re looking at, such as a different layout, a new vibe, or a page your design implies. Each one generates as a new frame alongside the source, so the original stays untouched and you can compare.

​
Build

The Build… menu on a selected Design frame graduates the design into a live, running app. The same menu also covers applying the design to an Artifact that already exists.
The Build menu open on a selected Design frame (APEX X1 Exact Replica) with the header 'Build or apply your designs', showing 'Build this design', which creates a new artifact, and 'Apply to an existing creation' listing the project's APEX X1 Design System and its Scroll Hero website

​
Build this design

Picking Build this design in the menu starts a new Artifact from the selected Design frame. The new Artifact lands in the project’s artifact list and becomes a live, running app. Build requires Core or Pro.

​
Apply to an existing Artifact

The Build… menu lists every Artifact in the project. Picking one applies the selected Design’s changes to that Artifact — Agent rewrites the Artifact’s code to match the design, leaving the Design frame on the Canvas for reference.

​
Focus

Focus zooms in on the selected frame so it fills the view, letting you work with it up close without the rest of the board. Select Focus in the action bar to enter it, and Exit focus at the top of the board to return to the canvas.

  • Toolbar — the floating toolbar; Generate creates new frames.
  • Elements — the individual pieces inside a frame.
  • Visual Editor — element-level edits inside a focused frame.
