What it is

AI chatbot UI design is the design of conversational interfaces for LLM-powered products: the message anatomy, streaming behavior, citations, input affordances, and failure states that decide whether users trust the output. It differs from classic chat design because the other participant is probabilistic and sometimes wrong.

Anatomy

The eight parts of an AI chat interface

Message thread

Clear user and assistant turns, with readable lists, tables and code.

Composer

Long prompts, attachments and voice, with an obvious send and stop.

Conversation starters

Suggested prompts that teach what the bot is good at.

Streaming

Text that appears as it generates, without the layout jumping.

Sources

Inspectable references attached to the claims they support.

Message actions

Copy, retry, edit and feedback, each one tap away.

History

Find, rename and resume past conversations.

Human handoff

A route to a person that carries the conversation along.

When it goes wrong

The states that decide whether users trust it

  1. 01

    Grounded versus generated

    Answers from your data look different from general model knowledge.

  2. 02

    Low confidence

    Uncertain answers say so and suggest how to check.

  3. 03

    Refusal with a way forward

    When the bot cannot help, it explains why and offers the next step.

  4. 04

    Timeouts

    A stalled response keeps what it generated and offers a retry.

  5. 05

    Correction

    Flagging or fixing a wrong answer takes one action.

  6. 06

    The wrong tool

    A clear way out when chat is not the right interface for the job.

Chat, copilot or agent

Choose the interface by the job

Chatbot

The job is asking questions and getting answers: support, document search, research.

See AI chatbot UI design

Copilot

The work already happens in your product and AI should help in place.

See AI copilot UI design

Agent

The AI does multi-step work on its own and the user supervises.

Got questions?

Frequently asked questions.

What does an AI chatbot UI design engagement include?+
The full conversational surface: message anatomy for user and assistant turns, streaming and loading behavior, citation and source display, input affordances (attachments, voice, suggested prompts), history and session patterns, and the failure states most teams skip: refusals, low confidence, timeouts, and wrong answers users need to correct. Delivered as build-ready Figma with a component set your engineers or AI coding tools implement directly.
Can you design a chat widget for our website as well as the in-app chatbot?+
Yes. Website chat widgets and in-product chatbots share components but differ in scope, entry points, and expectations. We design both against one system so the widget feels like a preview of the product, not a different company.
How much does chatbot UI design cost?+
On the subscription ($4,917/mo) a complete chatbot interface is typically designed inside the first two to three weeks alongside other requests. A focused one-off engagement starts at $3,000.
How do you design for wrong or uncertain answers?+
That is the core of the work. Grounded statements are visually distinguished from generated ones, citations are inspectable, low-confidence output invites verification instead of blind acceptance, and correction is one action rather than a support ticket. Users forgive an assistant that says it is unsure; they abandon one that was confidently wrong.
Do you follow existing patterns from products like ChatGPT and Claude?+
We start from the patterns users already know so your product feels immediately usable, then differentiate where your product genuinely differs. Novelty in a chat interface is a cost users pay; we spend it only where it buys something.
What should an AI chatbot UI include?+
At minimum: a readable message thread, an input that handles long prompts and attachments, suggested prompts for first use, streaming with a stop control, inspectable sources, per-message actions (copy, retry, feedback), conversation history, and a route to a human. The parts teams most often skip are the failure states: low confidence, refusals, timeouts, and wrong answers the user needs to correct.
How do you show sources and citations in a chatbot?+
Attach citations to the specific claim they support rather than listing sources at the end, and make each one inspectable in place, for example a hover or tap that shows the passage it came from. Distinguish answers grounded in your own data from general model knowledge. The goal is that checking an answer takes seconds, because most users will not check at all if it takes longer.
Should an AI chatbot stream its responses?+
Usually yes, because streaming makes a slow answer feel responsive and lets users stop a response that is heading the wrong way. It needs design work to feel good: the layout should not jump as text arrives, formatting like tables should not flicker while half-rendered, and there should always be a visible stop control. For short, structured answers, showing a brief loading state and then the complete result can read better.
How do you design human handoff in an AI chatbot?+
Make the route to a person visible before the user gets frustrated, not buried after three failed answers. When handoff happens, carry the conversation context across so the user never repeats themselves, tell them honestly how long a reply will take, and keep the thread readable when a human joins so it is clear who said what.
