Glass Canvas

Glass Canvas is a board that sits over your desktop. Add notes, writing, drawings, shapes, screenshots, and web cards, then arrange them spatially. It is not the Tasks list: Tasks tracks background work, while the board is a workspace for visual information.

Open the board

On Mac, the default shortcut is Option + Command + G. On Windows, it is Ctrl + Alt + Shift + G. You can also open it from the Board card in Studio, Settings → Agent → Board, the menu-bar item, or by asking Nock to open the board. The shortcut can be changed in Settings.

The board opens on the display under your pointer. Close it with the shortcut again or Escape. It is on by default; use Settings → Agent → Board to turn it off or change its shortcut.

Add and arrange items

The toolbar includes Select, Note, Writing, Pen, Paint, Shapes, Connect, Web card, and Screenshot. Hover over a tool to see its shortcut. You can paste or drop images, double-click supported shapes to edit their labels, and use Boards to start New board, Save a copy…, or open another saved board. Boards save as you work.

Use the zoom controls and ? help button to see board shortcuts. With a selected item, drag its corner to resize it. Use Undo if an edit is not right; Clear removes the board’s contents after confirmation.

Capture or open a web card

Use Screenshot to drag a screen region or capture the display. Nock hides the board during capture so it does not appear in the picture. On Mac, screen capture needs Screen Recording permission. Review a clip for private information before sharing it with an AI model.

A web card can show a still preview and become interactive when focused. Web cards use Nock’s browser profile, so a signed-in page may contain account information. Treat the board and its web cards accordingly.

Ask Nock to work with the board

While the board is enabled, you can ask Nock to read its contents, add or edit items, arrange them, or draw a diagram. For example: “Make a three-step diagram of this review process and label the decision.” Check every label and connection; an orderly diagram can still be wrong.

The board can be edited while it is closed using its saved contents. Nock’s task status and long-running work still belong in Tasks, not on the canvas. See Canvas workflows for examples.

Save and export

Choose Export to save a standalone web page. Open and Show in Finder let you inspect it. Exporting another page with the same board name replaces that exported page, so use a distinct name if you need to keep both versions. A web card inside an export may still depend on its source website.

Board contents stay on your computer, but when Nock reads board text it becomes context for the AI model. Web cards contact their websites. See Privacy, Permissions, and The browser.
