Chat Widget Embed

A feature for embedding Cloosphere chat into external websites like internal portals, customer support pages, and groupware. With a single script tag, provide AI chat on any web page.

Why You Need It

Existing Approach	Embed Widget
Users must directly access Cloosphere	AI chat directly inside the work system
Separate sign-in needed	Token forwarding or in-widget self sign-in
No external system integration	Supports UI bridge where AI reads and fills host page forms

Use scenarios:

Place an AI assistant in internal groupware to compose leave requests by chat
Embed a FAQ chatbot on customer support pages
Mount an operations support AI on the management console

Creating Widgets

Manage widgets in Admin > Settings > Embed Widgets.

Add widget

Click the + button to create a new widget.

Enter basic info

Field	Description
Name	Widget identifier (also used as default header title)
Description	Admin-side memo (not externally exposed)
Model/Agent	Pick Agent, Flow, or Model for the widget
System Prompt	Widget-specific system prompt (optional)

Edit design

Click the Design button to customize appearance (details below).

Activate

Set the toggle to Active in the widget list. Inactive widgets aren’t loaded externally.

Display Modes

How the widget appears on the host page — 6 modes supported.

Mode	Behavior	Default Size	Host Layout Impact
Bubble	Bottom-right (or bottom-left) floating button → chat panel popup on click	400×600px	None (overlay)
Side Right	Fixed panel on the right of the screen	380px width	Auto-applies `margin-right` to body
Side Left	Fixed panel on the left of the screen	380px width	Auto-applies `margin-left` to body
Side Bottom	Fixed full-width panel at the bottom of the screen	320px height	Reduces `html height` by panel size → content reflows upward naturally
Inline	Inserted inside a specified HTML element	100%×500px	None (within specified container)
Fullscreen	Full screen overlay	100vw×100vh	Host page is hidden

Bubble mode is the most common choice. Used only when the user clicks, with auto-responsive sizing on mobile (≤480px).Side modes auto-shift host page content without separate CSS/JS. To opt-out of this, add the data-cloosphere-no-shift attribute to the host page’s root element.

Bubble mode’s Bubble Open Style also supports 4 options: popup / side-right / side-left / side-bottom. Start as Bubble and specify how to expand on click.

Resizable Panel

Toggle on Resizable Panel in widget settings to let users adjust panel size.

Mode	Grip Position	Adjustable
Popup (Bubble)	Diagonal grip on top corner of panel (opposite to bubble)	width / height both directions
Side Right / Left	Vertical edge inside panel	width only (height stays 100vh)
Side Bottom	Horizontal edge on top of panel	height only (width stays 100vw)

Adjusted size is saved in localStorage per widgetId, so previous size is restored when the user revisits the same site.

Detect panel size changes from the host page

When panel size changes in Side modes, the following occurs:

CSS variable updates: --cloosphere-side-panel-width, --cloosphere-side-panel-height
Event published to host page: cloosphere:side-resize (payload includes width/height)

Subscribe to this event if you need to sync host page positions like sidebars or fixed headers with the panel.

Embed Code

Once a widget is created, a script tag to embed in the host page is provided.

<script
  src="https://your-cloosphere.com/static/embed/embed.js"
  data-widget-id="WIDGET_ID">
</script>

This single line auto-loads the widget. Override settings with additional data-* attributes:

Attribute	Description
`data-widget-id`	Widget ID (required)
`data-token`	Pre-authenticated user token (optional — skips sign-in if present)
`data-mode`	Override display mode
`data-theme`	Override theme (`light` / `dark` / `auto`)
`data-position`	Override button position (`bottom-right` / `bottom-left`)
`data-primary-color`	Override Bubble button color
`data-target`	Target CSS selector for Inline mode
`data-width` / `data-height`	Override size

Inline mode example

<div id="my-chat-container" style="height: 600px;"></div>
<script
  src="https://your-cloosphere.com/static/embed/embed.js"
  data-widget-id="WIDGET_ID"
  data-mode="inline"
  data-target="#my-chat-container">
</script>

Pre-authentication (SSO integration) example

<!-- Inject user token from host page -->
<script
  src="https://your-cloosphere.com/static/embed/embed.js"
  data-widget-id="WIDGET_ID"
  data-token="eyJhbGciOiJIUzI1NiIs...">
</script>

Don’t hardcode tokens directly in HTML. Render server-side dynamically or inject via JavaScript.

JavaScript API

Control the widget via JavaScript in Bubble mode:

// Open chat panel
window.CloosphereEmbed.open();

// Close chat panel
window.CloosphereEmbed.close();

// Replace token at runtime
window.CloosphereEmbed.updateToken("new-jwt-token");

open() / close() only work in Bubble mode. They’re ignored in Side, Inline, and Fullscreen modes since the widget is always visible.

Authentication Methods

The widget authenticates users via one of three modes. Pick the mode in the Auth tab of widget settings. Sign in directly with a Cloosphere account.

Priority	Method	Description
1	Token forwarding	JWT injection via `data-token` attribute or `updateToken()` API
2	Session restoration	Auto-uses tokens from previous widget sign-in saved in sessionStorage
3	In-widget sign-in	Sign-in screen shown when neither above is present

The sign-in screen auto-shows OAuth provider buttons (Google, Microsoft, etc.) configured in Cloosphere.

SSO Mode

Exchange the host site’s existing SSO token for a Cloosphere JWT. Use the existing auth system without a separate sign-in screen. Supported Providers:

Provider	Token Validation
Microsoft Entra ID	OIDC JWKS + id_token signature verification
Google	OIDC JWKS
GitHub	access_token → GitHub API verification
Generic OIDC	Discovery URL → JWKS auto-discovery

SSO Settings:

Setting	Description	Default
Providers	List of allowed Providers	—
Auto Signup	Auto-create unregistered users	off
Default Role	Role for auto sign-up	pending

Per-Provider additional settings

Provider	Setting	Description
Microsoft	Tenant ID	Single-tenant lock (empty = multi-tenant)
Microsoft	Trusted Audiences	Allowed client_id list
Google	Trusted Audiences	Allowed client_id list
Generic OIDC	Trusted Issuers	Allowed issuer URL list
Generic OIDC	Trusted Audiences	Allowed audience list

Host site integration example:

// Get Cloosphere JWT from host site using existing SSO token
const response = await fetch(
  'https://your-cloosphere.com/api/v1/embed-widgets/id/WIDGET_ID/auth/sso-exchange',
  {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({
      provider: 'microsoft',
      id_token: 'eyJhbG...',    // Existing SSO id_token
      access_token: 'eyJhbG...' // (optional) for additional profile info
    })
  }
);
const { token } = await response.json();
// Pass the obtained token to the widget via data-token

Guest Mode

Non-signed-in users can use the widget with simple info entry (or auto). Suitable for unrestricted-audience scenarios like customer support chatbots. Guest Settings:

Setting	Description	Default
Collect Info	Show name/email entry form	on
Required Fields	Required input fields	name
Optional Fields	Optional input fields	email
Auto Proceed	Skip info collection and start session immediately	off
JWT Expires In	Guest JWT expiration	24h

Enabling Auto Proceed starts chat immediately without info collection. Suitable for anonymous FAQ chatbots.

Domain Allowlist

For security, restrict which domains can load the widget. Register allowed domain patterns in widget settings’ allowed_domains:

Pattern	Matches
`example.com`	Exactly example.com
`*.example.com`	sub.example.com, portal.example.com, etc.
(empty)	All domains allowed

In production, always set the allowlist explicitly. Empty list is for testing only.

UI Manipulation Bridge

The most powerful feature of the embed widget — the AI directly manipulates the host page DOM. For example, when a user says “submit a leave request for today”, the AI can auto-fill the host page’s leave request form.

Available Tools

UI manipulation tools auto-attach to the agent, enabling:

Tool	Function
fill_form	Fill multiple fields in a form at once
fill_form_field	Set value on individual input field
read_form	Read the form’s current values as JSON
click_element	Click a button or link
highlight_element	Highlight an element with blue border + scroll (auto-clears after 2.5s)
get_page_info	Get current page URL, title, form list
navigate_to	Navigate the host page

Security: Selector Allowlist

Restrict the HTML elements the AI can manipulate using allowed_selectors in widget settings.

Setting	Behavior
`["*"]` (default)	All elements manipulable
`["form#leave-form *"]`	Only elements within a specific form
`["#name", "#date", ".btn-submit"]`	Only specified selectors

In production, explicitly restrict allowed_selectors. The default ["*"] lets the AI manipulate any page element, which can cause unintended behavior.

Cautions when using navigate_to

After navigate_to is called, host page navigation reloads the iframe and loses conversation context. Include guidance like “Don’t use additional tools after navigate_to” in the AI prompt.Within the same origin, soft navigation is attempted first. In SPAs (Single Page Applications), handling the cloosphere:navigate event enables routing without page transition.

Limitations

Item	Detail
Session persistence	Closing and reopening the widget starts a new session (previous conversation isn’t restored)
Chat title	Auto-title/tag generation is off, so chat appears as `Embed: {widget-name}` in Cloosphere chat list
UI bridge timeout	Tool fails when host page response isn’t received within 15 seconds
Mobile responsive	Only Bubble mode is auto-responsive. Other modes need manual width/height adjustment
sessionStorage	Token storage may be blocked in Private/Incognito mode
