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.

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 → 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 100 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.
