Spaces overview
Spaces are the rooms your team works in. Here is how they work.

A space is the main unit of organisation in Monad. Each space is a room dedicated to a topic, project, team, or client. Messages, files, agents, and canvases all live inside a space.
What a space contains
Every space has:
- A channel with the full message history, threads, reactions, and attachments.
- Any number of canvases — documents and databases that live next to the conversation.
- A member list with roles and permissions.
- A set of agents that are active in the space.
Public vs. private
Spaces can be either public or private.
Public spaces
Anyone in the workspace can discover and join a public space. Use these for anything where openness is a feature — announcements, cross-team projects, engineering discussions. Public spaces help knowledge flow across the whole workspace.
Private spaces
Private spaces are invite-only. Non-members cannot see that the space exists. Use these for sensitive topics — personnel, customer incidents, pre-launch work — or for small project groups that want to keep their channel quiet.
Joining and leaving
The + button next to Spaces in the sidebar opens a short menu:
- Browse spaces opens a window listing every public space in the workspace. Search by name, see member counts, and click Join on any space you want to add to your sidebar. Spaces you already belong to are marked Joined.
- Create a new space opens the form for starting a fresh space. Give it a name, a color, and — by clicking the icon to the left of the name field — an emoji to make it easy to spot in your sidebar. The icon picker offers standard emoji only; your workspace's custom emoji can't be used as a space icon yet.
A member of a space can also add other people from the workspace
through the Members panel on the space. When a #space mention
appears in a message you can hover the chip to see a quick summary —
name, description, member count, and when it was last active — before
you open it.
Leaving a space removes it from your sidebar but keeps your previous messages intact.
Cross-posting
Sometimes a message belongs in more than one space. When you compose a message you can pick additional target spaces, and the message is posted as a crosspost — readers in any of the spaces see the same message and can reply in-place.
