Projects
A project is the top-level container. It belongs to a team and holds one or more canvases, plus project-level settings (members, sharing, fonts).
Canvases
A canvas is an infinite 2D surface inside a project. Most projects start with a single canvas, but you can add more — for example, one canvas per scene, ad concept, or experiment.
Nodes
A node is a single unit on the canvas — text, image, video, audio, file, custom text, or group. See Nodes for types, anatomy, and how to create them.
Edges
An edge is a directed wire from one node’s output to another node’s input. See Edges & data flow for types and creation.
Runs
A run is one execution of a node against its model. Every run produces a new version on that node. Older versions are kept — switch between them with the version selector.
Versions
Each run on a node creates a new version. You can:
- Select which version is the “active” version (the one that downstream edges read).
- Compare versions side by side.
- Delete versions you no longer want.
@ mentions
Type @ in any prompt to reference another node. Melius treats the mention as an input edge — the referenced node’s output is wired into the prompt automatically. This is the fastest way to compose nodes without dragging wires.
Two ways to annotate the canvas:
- Sticky notes are lightweight yellow notes you drop anywhere on the canvas. Click to edit the text inline, drag to move them around, @-mention teammates inside the body. Only the author of a sticky note can edit or delete it — everyone else on the canvas sees it but can’t change it. No threads, no resolution.
- Comments are threaded discussions pinned to a point on the canvas or a specific node. They support replies, resolution, and @-mentions of teammates. Use them for review, feedback, and decisions you want to track.
Rule of thumb: sticky notes are for organizing the canvas; comments are for talking about the canvas.
Real-time collaboration
Every canvas is real-time and collaborative by default. Edits, runs, comments, and cursors sync instantly across every participant, including AI agents driving the canvas through the MCP server. You don’t enable collaboration or share a “session”; the canvas itself is the shared surface.
This powers:
- Presence — see who (or what) is on the canvas right now.
- Live edits — node moves, prompt changes, and new runs propagate as they happen.
- Comments and sticky notes — annotations show up for everyone immediately.
- Agent coordination — agents claim a region of the canvas while they work, so humans and other agents can stay out of the way.
Presence
Both human collaborators and AI agents appear on the canvas as cursors. When an AI agent is working, a highlighted area shows which part of the canvas it’s focused on, so you can see what it’s doing in real time.Last modified on May 18, 2026
