Canvas workflows
Turn notes and screen clips into a reviewable board, diagram, or exported page.

Use Glass Canvas when a task benefits from arranging information spatially. A board can hold notes, shapes, screenshots, and supported web cards. It is useful for comparing references or explaining a process without putting every detail into one chat message.
First enable the Beta feature under Settings → Agent → Glass Canvas. Follow Glass Canvas for its opening controls and platform shortcuts.
Gather a small set of references
Section titled “Gather a small set of references”Create a New board with a descriptive name. Add a note for the question you are trying to answer, then paste an image or use Screenshot to capture a relevant screen region. Check the clip for private information before asking the agent to interpret it.
Add a Web card for a supported secure page when the source needs to remain accessible. Web cards share Nock’s browser profile. A signed-in page can therefore contain private account information even though the board itself looks like a simple collection of cards.
Keep each reference identifiable. A short label explaining what a screenshot shows is more useful than several nearly identical unlabeled images.
Explain a process
Section titled “Explain a process”Ask for a bounded diagram: “Show these four steps from left to right and label the two possible outcomes.” Provide the actual facts rather than relying on the agent to invent the process. It can create shapes and connections, arrange items, and update labels.
Review the words and arrow directions before judging the appearance. A clean diagram can still reverse a dependency or omit a condition. Ask for a precise correction such as “Connect approval to publication only on the yes branch.”
Use selection and direct editing for small changes. Double-click supported shapes to change their labels. Connect adds relationships; layout requests can arrange a row, column, grid, or other supported pattern. Hover over tools to learn their shortcuts.
Preserve a useful version
Section titled “Preserve a useful version”Use Boards → Save a copy before a substantial rearrangement. Boards save while you work, so a separate copy is useful when you want to explore a different structure. Undo can recover an unwanted immediate edit, but it is not a substitute for keeping versions you need later.
Removing items or clearing a board needs confirmation. Read whether the action targets selected items or the whole board. If a requested change produces the wrong layout, undo it and make the next instruction more specific.
Export and check
Section titled “Export and check”Export creates an HTML page in Documents/Nock Canvases. Open that file and inspect it before sharing. An export is a snapshot, and embedded web content may still depend on a reachable external site. Exporting the same board name again replaces that exported page, so keep a separately named copy when you need both versions.
Board text read by the agent becomes model context. Screenshots and exports can also contain private information. Review the complete board before sharing it, including content outside the portion you were most recently viewing.
