Chat windows are a clumsy way to describe a button that needs to move three pixels to the left. Cursor is updating Design Mode to fix exactly that mismatch, letting you point at elements, scribble over a frozen viewport, or talk through a change while agents edit the source code in the background.

From the Cursor browser, you can click any element, draw on the page, or describe the change by voice, and Cursor gets the context it needs to edit the code while you move on to the next edit. The pitch is straightforward: UI work is spatial, so the instructions should be spatial too.

What actually ships in this update

Design Mode itself is not new. The browser-based visual editor first appeared in Cursor 2.2 and was rebranded inside the Agents Window with Cursor 3. This release layers on three concrete additions:

• Voice narration. You can now describe a change out loud instead of typing it.
• Multi-select with relationships. You can reference two components and ask the agent to make one match the other, remove repeated content, or adjust a group of components together.
• Drawing on a frozen frame.
