The canvas is the main workspace in Knouds. It is an infinite, zoomable grid where you assemble pipelines by placing nodes and connecting them with typed wires. Everything you build is saved with the workflow — including your current zoom level and pan position — so you pick up exactly where you left off.
ActionHow

Zoom in / outScroll wheel, or pinch on a trackpad
Fit all nodesUse the fit-view button in the canvas toolbar

Adding nodes

1

Open the node picker

Click the + button on the left sidebar to browse available nodes by category.
2

Choose a node

Browse categories (Inputs, LLMs, Image Models, Video Models, Music Models, Utilities, Custom) or search by name.
3

Place it on the canvas

Click a node in the sidebar to drop it at the center of your viewport, or drag it directly onto the canvas.

Connecting nodes

Every node exposes input handles on its left edge and output handles on its right edge. To create a connection, drag from an output handle to a compatible input handle. A wire (edge) appears between them carrying data from one node to the next.
Handles are typed. You can only connect handles of the same type, or connect any typed output to an any-typed input, which accepts all types.

Handle color reference

Handles are color-coded so you can tell at a glance what kind of data a wire carries.
TypeColorWhat it carries
imagePink #ec4899Image data
videoRed #ef4444Video data
textOrange #f97316Text strings, prompts, analysis output
audioCyan #06b6d4Audio files
mediaLight pink #f472b6Any media file (image, video, or audio)
aspect_ratioAmber #f59e0bAspect ratio value
resolutionGreen #22c55eResolution value
anyPurple #8b5cf6Accepts any data type

Selecting and deleting nodes

  • Select a node — click it. A highlight appears and the side panel opens with its settings.
  • Select multiple nodes — click and drag a selection box over them, or hold Shift and click each node.
  • Delete — select the node(s) and press Backspace or Delete.

Annotating your canvas

You can place sticky notes and text boxes anywhere on the canvas to document your pipeline or leave notes for collaborators. These annotation nodes have no handles and never participate in execution — they are purely decorative.
Use sticky notes to label distinct sections of a complex workflow, such as “Step 1 — Generate image” and “Step 2 — Animate to video”.

Viewport persistence

When you save a workflow, the canvas stores your current pan position and zoom level in the workflow’s viewport field (x, y, zoom). Reopening the workflow restores the exact view you were in. If no viewport was saved, Knouds fits the canvas to your nodes automatically.
