Usage

import { Bubble, BubbleContent, BubbleReactions } from "@/components/ui/bubble"

<Bubble>
  <BubbleContent>
    I checked the registry output and removed the stale route.
  </BubbleContent>
  <BubbleReactions>
    <span>👍</span>
  </BubbleReactions>

Composition

Use the following composition to build a bubble:

Bubble
├── BubbleContent
└── BubbleReactions

Use BubbleGroup to group consecutive bubbles from the same sender:

BubbleGroup
├── Bubble
│   └── BubbleContent
└── Bubble
    └── BubbleContent

Variants

Use variant to change the visual treatment of the bubble.

This is the default primary bubble.

This is the secondary variant.

This one is muted. It uses a lower emphasis color for the chat bubble.

👍

This one is tinted. The tint is a softer color derived from the primary color.

We can also use an outlined variant.

Or a destructive variant with a reaction.

🔥

Ghost bubbles work for assistant text, **markdown**, and other content that should not be framed.

This is perfect for assistant messages that should not have a frame and can take the full width of the container.

Ghost bubbles are full width and can take the full width of the container.

import {
	Bubble,
	BubbleContent,
	BubbleReactions,
} from "@/components/ui/bubble";

export function BubbleVariants() {
	return (
		<div className="flex w-full max-w-sm flex-col gap-12 py-12">

Variant	Description
`default`	A strong primary bubble, usually for the current user.
`secondary`	The standard neutral bubble for conversation content.
`muted`	A lower-emphasis bubble for quiet supporting content.
`tinted`	A subtle primary-tinted bubble.
`outline`	A bordered bubble for secondary or rich content.
`ghost`	Unframed content for assistant text or rich content.
`destructive`	A destructive bubble for error or failed actions.

A bubble sizes to its content, up to 80% of the container width. The ghost variant removes the max-width so assistant text and rich content can span the full row.

Alignment

Use align on Bubble to align the bubble to the start or end of the conversation.

This bubble is aligned to the start. This is the default alignment.

This bubble is aligned to the end. Use this for user messages.

import { Bubble, BubbleContent } from "@/components/ui/bubble";

export function BubbleAlignment() {
	return (
		<div className="flex w-full max-w-sm flex-col gap-8 py-12">
			<Bubble variant="muted">
				<BubbleContent>
					This bubble is aligned to the start. This is the default alignment.
				</BubbleContent>
			</Bubble>
			<Bubble align="end">
				<BubbleContent>
					This bubble is aligned to the end. Use this for user messages.
				</BubbleContent>
			</Bubble>
		</div>
	);
}

align	Description
`start`	Align the bubble to the start of the conversation.
`end`	Align the bubble to the end of the conversation.

Bubble Group

Use BubbleGroup to group consecutive bubbles from the same sender.

Can you tell me what's the issue?

Reactions

Use BubbleReactions for bubble reactions. You can use it to display reactions or quick action buttons. Use side and align to position the row.

I don't need tests, I know my code works.

👍😮

Bold. Fine I'll add some tests. I'll let you know when they're done.

Collapsible

Long bubble content can be composed with Collapsible to allow for a show more or show less interaction.

The accessibility review found two focus states that were visually too subtle in dark mode. I checked the dialog, menu, and drawer paths because each one renders focusable control...

"use client";

import { ChevronDownIcon } from "lucide-react";
import * as React from "react";

import { Bubble, BubbleContent } from "@/components/ui/bubble";
import { Button } from "@/components/ui/button";
import {
	Collapsible,
	CollapsibleTrigger,
} from "@/components/ui/collapsible";

const text = `The accessibility review found two focus states that were visually too subtle in dark mode.

I checked the dialog, menu, and drawer paths because each one renders focusable controls inside a layered surface.

The dialog and drawer are fine. The menu needs the hover and focus tokens split so keyboard focus stays visible when the pointer is not involved.

I also recommend keeping the change in the style file instead of the primitive so the other themes can choose their own focus treatment later.`;

const previewLength = 180;

export function BubbleCollapsible() {
	const [open, setOpen] = React.useState(false);
	const isLong = text.length > previewLength;
	const preview = `${text.slice(0, previewLength)}...`;

	return (
		<div className="flex w-full max-w-sm flex-col gap-8 py-12">
			<Bubble variant="muted">
				<BubbleContent>How can I help you today?</BubbleContent>
			</Bubble>

			<Bubble variant="muted" align="end">
				<BubbleContent className="whitespace-pre-line">
					<Collapsible open={open} onOpenChange={setOpen}>
						<div>{open || !isLong ? text : preview}</div>
						{isLong ? (
							<CollapsibleTrigger
								render={
									<Button
										variant="link"
										className="gap-1 p-0 text-muted-foreground"
									/>
								}
							>
								{open ? "Show less" : "Show more"}
								<ChevronDownIcon data-icon="inline-end" />
							</CollapsibleTrigger>
						) : null}
					</Collapsible>
				</BubbleContent>
			</Bubble>
		</div>
	);
}

Wrap a bubble in a Tooltip to reveal metadata on hover, such as when a message was read.

Did you remove the stale route?

Yes, removed it from the registry.

import { CheckIcon } from "lucide-react";

import {
	Bubble,
	BubbleContent,
	BubbleReactions,
} from "@/components/ui/bubble";
import { Button } from "@/components/ui/button";
import {
	Tooltip,
	TooltipContent,
	TooltipTrigger,
} from "@/components/ui/tooltip";

export function BubbleTooltipDemo() {
	return (
		<div className="flex w-full max-w-sm flex-col gap-4 py-12">
			<Bubble variant="secondary">
				<BubbleContent>Did you remove the stale route?</BubbleContent>
			</Bubble>
			<Bubble align="end">
				<BubbleContent>Yes, removed it from the registry.</BubbleContent>
				<BubbleReactions>
					<Tooltip>
						<TooltipTrigger render={<Button variant="ghost" size="icon-xs" />}>
							<CheckIcon />
						</TooltipTrigger>
						<TooltipContent>Read on Jan 5, 2026 at 4:32 PM</TooltipContent>
					</Tooltip>
				</BubbleReactions>
			</Bubble>
		</div>
	);
}

Pair a bubble with a Popover to surface more information on demand, such as the full error message for a failed action.

Run the build script.

Failed to run the command.

import {

	PopoverHeader,
	PopoverTitle,
	PopoverTrigger,

export function BubblePopoverDemo() {
	return (

Accessibility

Bubble renders the presentational message surface. Keep conversation-level semantics on the surrounding container and follow the guidelines below.

Labeling Reactions

Reactions render as a row of emoji. A screen reader reads each glyph with no context, and counters like +8 are announced as "plus eight". Group the row as a single image with a descriptive aria-label so it announces once. role="img" also hides the individual emoji from assistive tech, so no aria-hidden is needed.

<BubbleReactions role="img" aria-label="Reactions: thumbs up, fire, and 8 more">
  <span>👍</span>
  <span>🔥</span>
  <span>+8</span>
</BubbleReactions>

When reactions are interactive, render buttons instead and give icon-only buttons an aria-label.

<BubbleReactions>
  <Button aria-label="Thumbs up" variant="secondary" size="icon-xs">
    <ThumbsUpIcon />
  </Button>
</BubbleReactions>

Interactive Bubbles

When a bubble is clickable, render it as a real <button> or <a> with the render prop so it is focusable and exposes the correct role. BubbleContent ships a visible focus ring for interactive elements, and the accessible name comes from the bubble text. No extra label is needed.

<Bubble variant="muted" align="end">
  <BubbleContent render={<button type="button" onClick={onReply} />}>
    I forgot my password
  </BubbleContent>
</Bubble>
