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.Documentation Index

Navigating the canvas
| Action | How |
|---|---|
| Pan | Click and drag on an empty canvas area |
| Zoom in / out | Scroll wheel, or pinch on a trackpad |
| Fit all nodes | Use the fit-view button in the canvas toolbar |
Adding nodes
Choose a node
Browse categories (Inputs, LLMs, Image Models, Video Models, Music Models, Utilities, Custom) or search by name.
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.| Type | Color | What it carries |
|---|---|---|
image | Pink #ec4899 | Image data |
video | Red #ef4444 | Video data |
text | Orange #f97316 | Text strings, prompts, analysis output |
audio | Cyan #06b6d4 | Audio files |
media | Light pink #f472b6 | Any media file (image, video, or audio) |
aspect_ratio | Amber #f59e0b | Aspect ratio value |
resolution | Green #22c55e | Resolution value |
any | Purple #8b5cf6 | Accepts 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
Shiftand click each node. - Delete — select the node(s) and press
BackspaceorDelete.
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.Viewport persistence
When you save a workflow, the canvas stores your current pan position and zoom level in the workflow’sviewport 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.
