Collaborating
Invite people to a cluster as an editor or a viewer, by email or with a link. On Free and Creator, up to 10 people can edit across everything an account owns, at no cost to them, and viewers are unlimited. Cards and storage always count against the cluster owner's quota, not the person who added them.
Collaboration is free on Free and Creator: up to 10 people can edit across everything an account owns, and anyone can view. Inviting people is how boards become useful. A group with more than 10 people who edit uses Team, which is priced per seat.
Roles
| Role | Can |
|---|---|
| Owner | Everything, including deleting the cluster and managing members and shares |
| Co-owner | Runs a workspace alongside its owner — invites and removes members, changes roles, manages every share and link, renames it — but cannot delete it, hand it over, or remove the owner |
| Editor | Add, change and remove content; comment; invite if permitted |
| Viewer | Open, read, comment on the canvas and vote — never change content, including a document's text comments |
| Workspace member | The same two levels, editor or viewer, granted for every cluster in the workspace at once |
Editors are free on every plan. A free-tier account can be an editor on any cluster it is invited to, with no restriction on what it can do there.
Whose quota
Always the cluster owner's. A co-owner is not the owner for this purpose: what they add counts against the owner's allowance, like an editor's.
Cards added to someone else's cluster count against their card allowance; files uploaded there use their storage. This is what makes free editors workable: the person who owns the work pays for it, and inviting help costs nothing extra.
Up to 10 people who edit
On Free and Creator, an account can have up to 10 people who can edit, counted once each across every workspace it owns: the owner, co-owners, editors, and invites to edit that haven't been answered yet. Viewers never count.
When an account is full:
- Can edit is greyed out in the share panel, and people can still be invited to view.
- Someone who opens a link to edit joins as a viewer and is told why, and the owner hears about it.
- Anyone but the owner can ask the owner for a place.
- The owner sees everyone who holds a place in Settings → Members, and can make someone a viewer or cancel an invite to free one.
If an account ends up with more than 10 — a workspace handed over to it, for example — everyone keeps editing, and nobody new can be made an editor until it is back at 10 or fewer. Groups that need more use Team.
Inviting
Share on any cluster opens the panel, with inviting at the top. Two mechanisms:
- By email — name a person and a role. They get an invitation.
- By link — a URL carrying a role, which grants that access to whoever opens it and confirms.
Inviting someone who is new to Clusters also pays you both: they get bonus cards and 0.5GB of storage when they join, and you get bonus cards and 0.5GB once they get started. The panel says what it's worth under the invite box, Details there has the rest, and Referrals has the rules.
Also in the panel: current workspace members, existing per-board shares, and public links — which are a different thing, and always view-only.
Workspaces
Access can be granted at the workspace level instead of per board, which is the right shape for a team that works together continuously rather than on one project. To share a whole workspace, right-click it in the workspace switcher — or use its ⋯ — and choose Share workspace…: the share panel opens already set to invite people to every cluster in it.
A workspace has one owner, and can have any number of co-owners. The owner or a co-owner makes someone a co-owner from Settings → Members. Co-owners share the running of the workspace; deleting it and handing it to someone else stay with the owner.
Clusters shared with you appear under Shared with me in the sidebar, grouped by whose workspace they came from.
What collaboration looks like in use
- Presence — live cursors, who is here, jump to where someone is
- Comments — anchored to a card, a group, a point, or a text range
- Messages — direct and group conversations with anyone you share a board with
- Notifications — mentions, replies, invitations
Everything is real time. Two people can move cards on the same canvas, type in the same note, or write in the same document at once, and edits merge rather than overwriting.
One common shape of this is a studio art team working from a single live reference board — the shared reference boards guide covers setting one up.
Undoing someone else's change
⌘Z undoes your own edits only. To reverse a collaborator's work, use version history or workspace recovery — see Trash and recovery.
Frequently asked questions
Do collaborators need to pay?
No. On Free and Creator, up to 10 people can edit and anyone can view, and none of them pays. Whoever owns the cluster pays for what it holds. A group with more than 10 people who edit uses [Team](/docs/account/team), priced per seat.
Whose card allowance do collaborator uploads use?
The owner's. If you add cards to someone else's cluster, they count against their limit, not yours.
Can a viewer comment?
Yes, on the canvas. Viewers can read, comment and vote; they cannot add, move or change cards. Text comments inside a document need edit access — a viewer can read those threads but not add to them.
