Muse AI Glossary: Every Term, Plainly Explained

Agent basics

• AI agent — software that carries a task from request to finished output, not just an answer. Muse is one: you describe an outcome, it plans and acts.
• Artifact — a finished piece Muse produces: a document, web page, tracker, or dashboard you can keep, share, or revisit.
• Approval card — a structured pause where Muse shows you what it's about to do and waits for your go-ahead. Your checkpoint before anything consequential.
• Memory — what Muse remembers about you across conversations: preferences, facts, and standing instructions. You can review and edit it.
• Goals — long-running projects Muse advances in the background, checking in at milestones instead of needing constant prompting.
• Side chat — a separate conversation with its own context, so a new topic doesn't pollute your main thread.
• Proactive message — Muse reaching out on its own about something meaningfully new. You can dial these up, down, or off.
• Reasoning — the agent's internal plan for your request. You see the result; the plan is how it got there.

Access & account terms

Access mechanics change as the product rolls out — the invite code guide and availability guide stay current on the details.

• Invite code — a code from an existing user or Meta that grants access during limited rollouts.
• Referral code — a code you share so others can join; ours is on the community board if you need one.
• Redeem — entering a code to activate the access or credit attached to it.
• Early access — trying features before general release, usually with rougher edges.
• Availability — where and for whom Muse currently works. As of September 2026: the US and Canada.
• Waitlist — signing up to be notified when access reaches you.

Ways to reach Muse

• App — the main home: iPhone and Android apps plus desktop. See the app setup guide.
• WhatsApp — Muse inside your messaging app, best for quick thinking and deciding. See the WhatsApp guide.
• Voice mode — talking instead of typing; fastest for brainstorming and hands-free moments.
• Computer use — Muse operating a real browser or Mac desktop to finish multi-step bookings and forms, with your approval at checkpoints.
• Connectors — permissioned links to your calendar, inbox, and other services so Muse works from real data.
• Channels — the general word for wherever a conversation happens: app, messaging, or voice.

Cost & limits

• Tokens — the units of text (and work) AI models process; heavy usage is measured in them.
• Usage limits — caps on how much you can do in a period; they vary by plan and account.
• Free tier — what you can do without paying. The specifics change, so check the cost guide for the current picture.
