What is Harmony Companion?
Companion is Harmony’s AI assistant. It lives inside your workspace and can answer questions, draft content, search your meetings, use connected tools, and help you take action with the context Harmony already has.
Your interface to workspace intelligence
Unlike a generic chatbot, Companion can work with the data you have permission to access in Harmony:
Recall information: "What did Acme say about pricing in our last five calls?"
Analyze trends: "What objections came up most often this month?"
Draft content: "Write a follow-up email from today’s demo."
Use tools: "Create a Linear issue for the bug John mentioned."
Search the web or fetch URLs: Ask Companion to combine workspace context with live external information. Web search is powered by Exa.
Companion cannot bypass your workspace permissions. If you can only see your own or team conversations, Companion is limited to the same scope.
Where to find Companion
You can use Companion in three main places:
Full page: Click Companion in the sidebar to start or continue a thread.
Conversation context: Open a meeting or call and choose Discuss with Companion to ask questions about that specific conversation.
Desktop app: Use the floating Companion window in the Harmony desktop app for quick chat and context while working in other apps. Voice input is currently a desktop-only feature.
Threads, spaces, and models
A thread is one conversation with Companion. Threads are saved automatically and keep their own history.
A space groups threads and can add shared background context, so you do not have to repeat the same instructions in every thread.
Companion supports a broad model catalog across providers such as OpenAI, Anthropic, Google, Mistral, Groq, and OpenRouter. Your workspace admin controls which providers and models are available. You can choose your personal default in User preferences > Models, and you can choose a model for a new thread before sending the first message.
Once a thread has messages, its model is locked. Start a new thread to switch models.
Tools and approvals
Companion uses tools when it needs to do something outside plain text generation, such as reading a meeting transcript, searching contacts, creating a note, sending an email, or using an integration.
Read-only tools often run automatically. Tools that modify data or take external action usually ask for confirmation first. You can configure trusted auto-approval patterns in User preferences > Companion.
Important reminder
Companion can make mistakes. Treat its answers, summaries, and drafts as assistant output that you should review before acting on, especially for customer communication, calculations, legal or compliance topics, and external tool actions.
