Conversational UI — Conversational User Interface
What is Conversational UI?
Conversational UI (CUI) is an interaction design pattern where a person completes a task by typing or speaking in natural language — through chat or voice — instead of navigating fixed menus, forms, or button taps. The system parses free-form input, holds context across turns, and replies in kind, so a single back-and-forth thread replaces what a traditional graphical interface would spread across multiple screens or an IVR menu tree. Conversational AI is the technology that powers a conversational UI.
More detail
Conversational UI is the interface layer a person sees and interacts with; conversational AI is the underlying technology (NLP, dialog management, an LLM) that understands the input and generates the response — a chat widget or phone call is the CUI, the AI agent behind it is the conversational AI.
Because there's no fixed menu to browse, a well-designed conversational UI still needs guardrails: a clear fallback when the system doesn't understand, an easy path to reach a human, and visible confirmation before an action like a payment or booking actually executes.
On Orbit, conversational UI spans phone calls, SMS, WhatsApp, and web chat — the same AI agent framework and dialog context carry across channels, so a conversation can start in chat and hand off to voice without the person repeating themselves.
Frequently asked
- What's the difference between conversational UI and conversational AI?
- Conversational UI is the interface a person types or speaks into — a chat window or a phone call. Conversational AI is the underlying technology that parses natural language and generates a response. The UI is what the user sees; the AI is what powers it.
- Is a chatbot with a fixed decision-tree menu a conversational UI?
- Not really — a menu-driven bot still constrains input to a small set of buttons or keywords. A conversational UI specifically accepts open-ended, free-form language and lets the underlying system interpret intent, rather than requiring the person to pick from a preset list.
