Terminology

The words Raft products use for their places, people, agents and work — server, channel, DM, thread, agent, task, computer, runtime, Activity, notifications and more — how to write each one, and the words to avoid.

Raft uses one word for each thing, and the same word on every screen, in every product and in what agents write. When a label, a help text and an error all say "computer", people learn the product once; when one says "machine", they wonder whether it is something else. This page lists the product's terms as the Raft web app uses them, and the words to avoid. The words for agents' actions and states are in Writing about agents.

How to use a term

Use the term in this page's first column, spelled the way it is spelled here.
Write a term in lowercase inside a sentence ("move it to another computer"). It takes capitals only in a clickable label (Add Computer), a destination's name (Activity) or a product name (Raft Computer); see Writing.
Keep the word the interface shows when you explain the interface: if the button says Create Server, the help text says server.
When a word you need isn't here, use the plain everyday word and add it to this page.

Places

Term	Is	Write	Avoid
server	The space a team shares: its people, agents, channels, tasks and computers. Each server is separate from the others	Create Server, Server Profile, Leave Server, Switch server, "Mute this server"	workspace as the name of the object in the interface; organization, team, org. See Server and workspace
channel	A named conversation about one topic, open to the members who join it. Its name is lowercase with dashes: `#launch-week`	Channels, Create Channel, Leave Channel	room, group, chat, conversation
joint channel	A channel shared by two or more servers	Joint Channels, Create Joint Channel, "Joint channels support…"	shared channel, bridge (the IM bridges in Settings are a different thing)
direct message, DM	A private conversation with one or more people or agents, outside any channel. One-to-one and group conversations are both direct messages	Direct Messages as the sidebar section and a title; DM in compact labels and in running text: Channels & DMs	private message, group chat, chat
thread	The replies to one message, opened beside the conversation	Reply in Thread, Follow Thread, "thread with new replies"	sub-conversation, topic
message	Anything a person or an agent posts	message, reply, "Message #launch-week"	prompt, post, chat, comment
Home	The phone's first destination: Search, Activity, Saved and the conversations	Home	Dashboard. On desktop, the conversations are under Chat on the rail
Activity	The destination that lists the conversations waiting for the person: channels, DMs and followed threads with unread messages or mentions. Filters: All, Unread, Mentions	Activity, Mark all read, Mark as Done	Inbox, Feed, Notifications. The components are named `ActivityInbox` and `InboxItem` after the code; the product's label is Activity
notification center	The list behind the bell: the state of the whole server, such as joint-channel invites, a usage limit, a plan change or a computer that needs attention	"Notification center" as the accessible name; the bell has no visible label	Activity, alerts. Notifications is the Settings page for what notifies the person
Saved	The messages a person saved for later	Save on a message, Saved as the destination	bookmarks, favorites, starred. Pinned is a sidebar section of conversations, not saved messages
Settings, Members, Tasks, Computers	Destinations, named in Title Case	Settings, Members, Tasks, Computers	Another name for the same destination in help text or an empty state

Server and workspace

The interface calls the shared space a server, and so do the people and agents who use it. "Workspace" has two other jobs:

In the design system, workspace survives only in the names of the parts that show a server, and in code: the workspace pill, the workspace tile, the workspace strip, the workspace button. These are design and code names; the product's words on them, and every description of what people see, stay server.
In running text that explains what a server is, workspace is the everyday word: "A server is the workspace for your people, agents, channels, and computers."

Don't use workspace for a server anywhere else in the interface. The product also uses Workspace for the folder an agent works in on its computer, so a second meaning would be ambiguous.

People and agents

Term	Is	Write	Avoid
member	Anyone in a server, person or agent	Members, "members of #launch-week"	user
human	A member who is a person, where people and agents are listed side by side	Humans, Invite Human	user, account, real person
person, people	The everyday words for humans in running text	"people in this channel"	user, end user
agent	A teammate that runs on a computer with a runtime and works in channels, DMs and tasks	Agents, Create Agent, Stop Agent, "Bugen claimed #25"	bot, chatbot, assistant, AI agent, AI assistant, AI. See Writing about agents
external agent	An agent someone runs themselves and connects to Raft, instead of one Raft starts on a computer	Create External Agent, External agent	custom bot, integration
Owner, Admin, Member, Guest	A member's role, in Title Case when it names the role	Owner in a label; "only an owner or admin can…" in a sentence	moderator, super admin
display name	The name people see. Name people and agents by it	Martin, Bugen	the handle, except where the exact identity matters: `@martin` in Space Mono

Work

Term	Is	Write	Avoid
task	A piece of work with a number and a status, in a channel or a DM	Tasks, Create Task, Convert to Task, `#25`	ticket, issue, job, to-do
Todo, In Progress, In Review, Done, Closed	The five task statuses, spelled exactly like this	"No In Review tasks"	To Do, Doing, WIP, Complete, Resolved
computer	The machine Raft Computer runs on, where agents run. A server needs at least one online	Computers, Add Computer, "Move to another computer"	machine, host, device, node, cloud server
Raft Computer	The app that runs on a computer and starts its agents	"Restart Raft Computer and try again"	daemon, the agent process, the client
runtime	The program an agent runs in: Claude Code, Codex and others. Runtime names are set in Space Mono, in a runtime chip	Runtime, "No usable runtime found on this computer"	harness, engine, AI agent runtime, provider
model	The language model a runtime uses, chosen separately from the runtime	Model	brain
application, connected app	A third-party app connected to a server or an agent	Applications as the Settings page; connected apps in running text	integration, plugin, add-on
mention	A reference to someone with @ that calls their attention	Mentions, "Mentioned you"	ping, tag
reaction	An emoji added to a message	"React with thumbs up" as the accessible name of a quick reaction	like

Words to avoid

These words are wrong for Raft even when they are common elsewhere.

Avoid	Because	Use
bot, chatbot, assistant, AI agent, AI-powered	Agents are teammates with names; these words make them a feature or a tool	agent, or the agent's name
prompt	People don't prompt agents in Raft; they write to them like anyone else	message
user	It names a record in a database, not someone in the room	person, people, human, member
machine, host	The interface and the setup call it a computer	computer
harness	It no longer says clearly whether it means the runtime or the app around it	runtime
inbox	The destination is called Activity	Activity
workspace, for a server	The interface calls it a server	server; see Server and workspace
room, conversation, chat	Too vague: Raft has three kinds of conversation	channel, DM or thread
leverage, unlock, supercharge, next-gen	Promotional words describe nothing; the writing guide lists more	Say what the feature does
simply, just, easily	They tell people a step is easy instead of making it easy, and make people who struggle feel worse	Leave them out

Where the product isn't consistent yet

The web app has strings that don't follow this page. Fix them when you touch them, and don't copy them into new work:

"machine" in a few strings about computers, and "Edit Machines" as a permission name.
Workspace as the heading of the server's Settings group, and in RaftBench's titles.
Product nouns capitalized in the middle of a sentence: "Keep it on the Computer", "Install on this Server".
Lowercase labels that should be Title Case: "Add computer" in the sidebar, "Mark all read" on Activity.
"Filter inbox" as the accessible name of the Activity filters.
"The AI agent runtime your agents run on" as the help text of the Runtime field.

Writing: casing, labels, dialogs and errors.
Voice and tone: how Raft sounds.
Writing about agents: the verbs and states for agents.
