Workspace

A workspace is your team’s space in Rydhm. It holds your experts, their knowledge, tools, phone numbers, conversations and billing. Everything you create belongs to one workspace, and the top bar always shows which one you’re in.

Members and roles

People join a workspace as an admin or a member (a workspace can also have an owner).

Admins create, configure, publish and delete experts, manage knowledge and tools, and see billing.
Members talk to experts, read their settings and conversations, and can edit an expert’s name, description, picture and background. Tabs an admin manages show a lock and read-only values.

See Members and roles.

Expert

An expert is one AI agent. It has:

Part	What it decides	Where you set it
Persona and first message	Who it is, how it behaves, what it says first	Profile tab
Variables	Blanks like `{{name}}` filled in for each conversation	Profile tab
Guardrails	How strictly it stays on topic, rules, blocked topics	Profile tab
Knowledge	What it knows	Knowledge tab
Voice engine, voice and languages	How it hears, thinks and speaks	Voice tab
Call experience	Turn-taking, silence, call length, background sound	Voice tab
Tools and specialists	What it can do, and who it can hand a call to	Tools tab

The expert editor also has Phone, Meetings, Share and Analysis tabs for its channels and results. An expert has an Active switch on its Profile tab: when it’s off, customers can’t talk to it.

Voice engine

The voice engine is how an expert turns speech into speech. There are three:

Pipeline: a transcriber, a language model and a voice, each chosen separately. The default.
Gemini Live: one Google model hears and speaks.
GPT-Live: OpenAI’s full-duplex model, which listens while it speaks. One-on-one conversations only.

See Voice engines.

Knowledge

Knowledge is the material an expert answers from: files, pasted text, pages imported from a website, and question-and-answer sets. An expert has its own knowledge, and can also use shared knowledge that several experts read at once. When an expert’s knowledge is small, it reads all of it on every turn; when it is large, it searches it for each question. See Knowledge overview.

Tools

A tool is something an expert can do during a conversation: end the call, look up a calendar, send an email, search the web, or call your own API. Some tools ask the caller to confirm before they act. See Tools.

Channels

A channel is a place people reach an expert:

inside the app: the Test panel, chat and calls from the Experts page;
a share link and the website widget;
phone numbers and outbound campaigns;
meetings on Google Meet, Zoom and Teams;
the API, SDKs, MCP and agent-to-agent access.

Visibility

Every expert is Private, Unlisted or Public:

Private: only your workspace can talk to it.
Unlisted: anyone with its link can talk to it, by voice or chat.
Public: anyone can, and it is listed in the public directory.

You change visibility with Publish in the expert’s header. Usage on an Unlisted or Public expert is billed to your workspace.

Members and visitors

Rydhm treats two kinds of caller differently:

Members are signed in to your workspace: the Test panel, in-app chat and calls, and meetings an expert joins for you.
Visitors are everyone else: share links, the website widget and phone callers.

A visitor’s conversation can use the expert’s knowledge, its conversation controls and web search. Actions on your workspace (calendar, email, your own API tools, outside tool servers, hand-offs) run only for members. See Tools.

Conversation

A conversation is one chat, call or meeting with an expert. Rydhm keeps its transcript, and can summarize and analyze it. All of them are listed under Conversations in the sidebar. See Conversations.

Version

Each time an expert is created, saved, published or restored, Rydhm keeps a version: a snapshot of its settings, with who made it and what changed. You can compare versions and restore one. See Versions and testing.
