Nodes are the building blocks of a canvas. Asset nodes hold what you upload, and generation nodes call the AI to produce results. This chapter covers how to add nodes to the canvas and which types there are.

## Ways to add a node

You can create a node from any of these:

- Double-click empty space, long-press on a touch screen, or press Tab: the “Add node” menu opens (with Tab, in the middle of the view); pick a type to create it;
- Right-click empty space: choose “Add node” in the context menu. The same menu also has “Place workflow”, “Upload”, “My assets”, “Undo”/“Redo”, “Paste” and more;
- Click the “+” beside a node (“Generate from this node”): it lists the downstream nodes you can create from that node's output type, showing only what the source can actually feed. For example, the “+” on the right of an image has “Video” (generated as image to video) and “First & last frame”. On the right of a video, “Video” creates a video node in Omni reference mode, and “Video processing” covers extend video, edit video, segment remake and lip sync. On the right of an audio node you'll find voice changer, voice isolator, generate from reference audio, and dubbing;
- Click the “+” beside a node (“Generate upstream node”): a menu opens from the input handle, so you can create an upstream node of the input type you need, connected automatically;
- Drag a connection out of a handle and release it on empty space: a menu of matching types opens where you let go; pick one to create and connect it automatically;
- Drag files from your computer onto the canvas: drop images, videos, audio or documents straight in, and asset nodes are created and uploaded automatically;
- Paste (⌘/Ctrl + V): when the clipboard holds an outside image, you get a new image asset node; when it holds nodes copied inside the app, you get copies of those nodes.

## Node types at a glance

These are the main node types you can create directly and generate with:

- Image / video / audio / document assets: hold the files you upload and serve as inputs for later generations (created by uploading, dragging or pasting);
- Image generation: turns text into an image, or edits an image when you connect one (image to image). Choose “Image” in the “Add node” menu;
- Video: turns text into video and also covers Omni reference, image to video, first and last frames, image reference and other modes; a small tag next to the node title shows the current mode. Choose “Video” in the “Add node” menu;
- Video processing: extend video, edit video, segment remake and lip sync. Create it from “Video processing” in the “Add node” menu or from the “+” beside a video node;
- Audio: “Audio” in the “Add node” menu holds voice and music (entries with no available model right now are hidden). Create speech to text from the “+” beside an audio node, then “Text”;
- Avatar: pairs a portrait with a driving audio clip to generate a video of the person speaking. Choose “Avatar” in the “Add node” menu (marked “New”), or create it from the “+” beside an image or audio node;
- Text generation: lets the AI continue or rewrite text. Choose “Text” in the “Add node” menu;
- Smart Cut: a timeline container for editing several clips together; it opens a full-screen multi-track editor. Choose “Smart Cut” in the menu (marked Beta);
- Director Stage: a 3D stage where you place cameras and characters and take screenshots to use as reference images. Choose “Director Stage” in the menu (marked “New”).

## Billing

Asset nodes and local edits don't call paid models. Generation and analysis are billed at the selected model's quote, so check the quote before you submit. When Sumi generates for you, whether it asks before each one depends on the conversation's permission level.
