Sources.
A source is a piece of reference material — a logo, image, SVG, link, or note — saved to your workspace library and attached to a composition. It’s a searchable, placeable asset shelf: you (and your agent) pull from it while designing. The library is workspace-wide, so the same assets are reusable across every file.
Add & manage sources
The Sources tab in the left panel — “Reference material the assistant can draw from.”
Open the composition’s left panel and switch to the Sources tab. It lists the sources attached to this file; the ＋ button and Manage open the full library manager. You can add three ways:
- Upload an image or SVG — drag-and-drop, multiple files, up to ~12 MB each.
- Add a link — paste a URL to reference.
- Add a note — type reference text (a brief, a spec, a description).
On any source card, ＋ Canvas drops that asset straight onto the open composition. Sources you add here are tagged to this file but live in your workspace library, so they show up when you search from any composition.
How the AI uses sources
The honest version — worth reading, because it's not what the tooltip implies.
Adding a plain image, link, or note to a file does not automatically feed it into the assistant’s context. Instead, the agent reaches your sources on demand: it searches the library and places the assets it wants onto the artboard.
canvas.list-sources { query?, kind? } # search your library
canvas.place-source { sourceId, x?, y? } # drop an asset onto the canvasTwo things are automatic, and it helps to know the difference:
- Saved styles & components (a different kind of library item) are surfaced to the agent every turn, so it reuses them instead of rebuilding.
- On-brand color, type & voice come from your brand kit, not from the Sources library — that’s what steers generated style.
So think of sources as a reference shelf you and the agent search and place from, not an automatic style feed. If you want the agent to use a specific logo or image, ask it to (“place my logo from sources, top-left”) or drop it on the canvas yourself. The agent-facing surface is documented in the Canvas API.
Sources vs references vs reference-images
Three features share the word — keep them straight.
| Term | What it is |
|---|---|
| Sources | Library assets (logo/image/SVG/link/note) attached to a file — searchable and placeable. |
| References | Links to other compositions (a "see also" between files), set in the right panel. |
| Reference-images | Images attached to a single image-generation for image-to-image — per-generation, not saved. |
Team sources
Share a composition as reference material for your team. (Professional plans.)
On a team workspace you can publish a composition as a team source — reference material teammates can pull into their own work. It’s a Professional-tier feature; on a solo Free workspace the option is an upgrade prompt.
