Clusters

A cluster is a board, and clusters nest inside each other without limit — which is how a project becomes a folder tree without anyone building one. Clusters are never capped on any plan. Each one gets an automatic thumbnail rendered from its actual contents, or a cover image you choose yourself.

A cluster is the unit of work: a project, a scene, a pitch, a moodboard. The code and the API call the same object a board.

Creating one

  • New cluster in the sidebar
  • ⌘K → "create cluster"
  • The Add cluster tool on any canvas, which creates it nested inside the current one
  • Right-click a canvas → Add → Cluster

Clusters are unlimited on every plan, including free. Only cards are capped.

Nesting

A cluster inside a cluster appears as a card on the parent's canvas that opens into its own canvas. There is no depth limit.

This is how structure emerges without anybody designing it: a film becomes scenes, a scene becomes setups, a setup becomes a reference wall — each a real board you can open, share and work on independently.

Moving a cluster: drag it in the sidebar tree, or drag it onto another cluster's card on a canvas. Moves are cycle-safe — dragging a cluster into one of its own descendants is refused rather than creating a loop.

Linked clusters are different: a reference to a cluster that lives elsewhere, placed on this canvas. The board itself does not move. Use it when something belongs in two places.

Side by side

Two clusters can be open at once, in a split view with a draggable divider.

  • The ⧉ Pin alongside button in the topbar
  • ⌘K → "Open split view"

Then pick the cluster for the right-hand side. Close it with the × at the top-right of that pane, or the same topbar button.

Each side navigates itself. Opening a nested cluster on the right moves the right side only — the left stays where it was. The same holds for what you drop, link and edit: it lands on the side you did it on.

One toolbar, and it follows you. There is no second bar inside the split. The breadcrumb at the top always describes the side you last clicked into, so it is where you go to see where you are and to climb back a level; Back and Forward move that side too, and the sidebar highlights that side's cluster. The active side is outlined in gold.

Access is per side too. If the right pane is showing a cluster someone shared with you as view-only, it is read-only there, exactly as it would be full screen.

The split — both clusters, both breadcrumbs, and the divider position — is remembered, so a reload puts you back in it. It is a desktop feature; there is no split on phones.

A document docked beside the canvas uses the same right-hand pane, so opening one closes a cluster split, and vice versa.

Thumbnails

Every cluster gets a thumbnail rendered from what is actually on it — a miniature of the board, not a generic icon. It updates as the board changes.

To override it, right-click the cluster:

  • Cover colour — a flat colour instead of a render
  • Upload custom thumbnail — your own image, with a 16:9 crop and reposition step
  • Reset to auto thumbnail — back to the generated render

A custom thumbnail is respected — editing the board afterwards will not silently overwrite the image you chose.

Views

Every cluster has two views of the same contents:

  • Canvas — the infinite surface, where position means something
  • List — a sortable, searchable file browser

Switching does not convert anything. Settings → Card defaults sets which view new clusters open in.

Finding clusters

  • The sidebar tree expands lazily, so a deep hierarchy stays fast
  • ⌘K searches cluster names alongside everything else
  • Recents surfaces what you have had open
  • Home shows the whole workspace as a relationship graph
  • Shared with me groups clusters other people have invited you to, by whose workspace they came from

Deleting

Deleting a cluster is a soft delete. It goes to the trash and stays restorable for 30 days. See Trash and recovery, which also covers version history and rolling a whole workspace back to a point in time.

Frequently asked questions

Is there a limit on how many clusters I can make?

No. Clusters are unlimited on every plan, including free. Only cards are capped, at 50 on the free Demo plan.

How do I move a cluster somewhere else?

Drag it in the sidebar tree, or drag it onto another cluster's card on a canvas. Moves are cycle-safe — you cannot make a cluster its own ancestor.

Where do deleted clusters go?

To the trash, for 30 days, from which they can be restored. See Trash and recovery.
