Your first channel
Create your first channel in Nebula. Channels are workspace-scoped rooms where threads, agents, and teammates collaborate on a topic.
A channel is a topic-based room your whole workspace can use. Inside it, conversations split into threads, each with its own context and an auto-generated summary.
Create a new channel
Channels group conversations by topic. Give your channel a name to get started.
Will be displayed as #project-planning
All workspace members
Invite-only members
Opening the modal
Open the command palette with ⌘K and choose Create channel — or just ask Nebula in chat (below).
Give the channel a name. Nebula slugs it for you — "Project Planning" becomes #project-planning.
Pick a visibility (see below), then Next to add members or agents.
Or create one in chat
Create a new channel called grad-party and invite Nebula and the Party Planner.
Creating #grad-party channel with workspace visibility.
Done — #grad-party is ready. I added Nebula and Party Planner. Want me to start a thread for venue ideas?
Workspace vs Private
| Workspace | Private | |
|---|---|---|
| Who can find it | Everyone in the workspace | Only invited members |
| Who can post | Workspace members | Channel members only |
| Lock icon on the channel | No | Yes |
| Best for | Team-wide topics, ongoing projects | Sensitive work, small subgroups, drafts |
Pick Workspace unless you specifically need privacy. Discoverability is a feature — most channels benefit from being open to whoever is curious.
What happens after you create one
The channel joins the Channels lane in your sidebar, and it shows up in search. Anyone with access can open it to see the thread list. Click + Start new thread to begin the first conversation — Nebula will auto-title and summarize as messages come in.
See Channels & threads for the channel layout and Threads for how threads work.
Channel names that age well
Need help? Ask Nebula directly in chat — it can create, rename, and invite members to channels for you. For bugs or anything unresolved, email support@nebula.gg. See Support for more options.
