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 are where conversations happen. Give your channel a name to get started.
All workspace members
Invite-only members
Opening the modal
In the sidebar, click + next to Channels.
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 in your sidebar. 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 in sidebar | 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 appears in the Channels section of your sidebar with a # prefix. Anyone with access opens 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.
