Building in SpaceLab
The canvas, toolbar, node palette, connections, and Ask AI copilot.
Updated July 19, 2026
This covers the canvas itself: the toolbar, the node palette, connecting nodes, and Ask AI, the copilot that can build the graph for you.
The canvas
The canvas is your draft workspace. It auto-saves the workflow document as you edit, but auto-save only saves the canvas, not the published form. The form is only written when you explicitly Publish. The canvas is the source of truth; the form re-derives from it.
The bottom toolbar
| Control | What it does |
|---|---|
| Add | Opens the node palette to drop a new node |
| Select | Default pointer, click/drag to select nodes |
| Pan | Grab and move around the canvas |
| Cut | Remove the selected node |
| Group / Ungroup | Box 2+ selected nodes into a labeled frame, or split one back apart |
| Undo / Redo | Step backward/forward through edits |
| Ask AI | Open the AI copilot to build or edit the graph for you |
| Run | Execute the whole Space |
The node palette
Open the palette (left side, or Add) to browse or search all node types. Nodes are organized into eight categories: Inputs, Text, Image, Video, Audio, Logic, Output, Notes.
Start from Inputs, transform through Text/Image/Video/Audio, control flow with Logic, and finish at Output. Search filters by name and description, so typing "kling" or "background" jumps straight to the right node.
Connecting nodes
- Each node has input sockets (left) and output sockets (right).
- Drag from an output to a compatible input to create a connection; this is how data flows.
- The inspector (right panel) shows the selected node's settings: model, prompt, dimensions, required flags, and advanced options.
Ask AI, the build-it-for-you copilot
Ask AI is SpaceLab's canvas copilot, found in the bottom toolbar and on the new-canvas landing. Instead of dragging every node by hand, describe what you want in plain language and Ask AI assembles or edits the graph for you.
- Build from a brief: "Take an uploaded product image, remove the background, place it on a studio backdrop, then make a 6-second Kling video." Ask AI adds and wires the right nodes.
- Edit an existing graph: ask it to add a subtitle step, swap the video model, or add a download node, and it modifies the canvas in place.
- Iterative: it streams changes into the canvas as a chat-style conversation, so you can refine step by step.
Ask AI is the fastest way to get a working first draft. Build the skeleton with Ask AI, then fine-tune models and prompts node by node in the inspector.
