This page covers two settings tabs that sit close together because they both shape what your users — and external sites — see when they reach your Digital Twin.

Visual Branding

Name, logo, colors, custom CSS — the look and feel of your Digital Twin.

Public URLs

The allow-list of websites (origins) that may embed or launch your Digital Twin from the outside.

​
Visual Branding

Branding is set on each Digital Twin under Admin → Instances → edit a Digital Twin → Personalization and AI Models (sections Name & Avatar and UI & Appearance); the picture and AI Name are also under Instance Settings → General, the theme and backgrounds under Instance Settings → Personalization. Most fields apply immediately on save — refresh any open tab to pick them up.

​
Name and avatar

​
string
The display name for your Digital Twin. Defaults to “Pria”. Shown in the chat header, the welcome screen, and the browser tab title.
​
image
Light-mode logo. Click the avatar to upload. Square aspect ratio works best (we render it at 192×192 in most places).
​
image
Background URL (Large Picture) — the page background. Dark Mode Background URL (Large Picture) is its dark-mode counterpart. Both optional.
​
image
Animated Picture URL (GIF) — optional; when set, it replaces the twin’s picture wherever the twin is shown (the twin list, the Convo screen, the chat avatar).
Click the avatar itself to launch the upload dialog — there is no separate Upload button. The same pattern applies to user, Digital Twin and assistant avatars across the product.

​
Theme and colors

​
enum
UI Theme: Dark Mode, Light Mode, or User Directed (each person picks in their profile). Most Digital Twins should leave it on User Directed.
​
string
Custom CSS applied across the whole Digital Twin UI. Use this for primary color, accent color, button shapes, font choices, and layout tweaks. See UI Customization for the full class reference and a starter template.

​
Where branding shows up

​
Public Authorized URLs

The Public Authorized URLs list is the list of websites (like https://school.edu) permitted to launch or embed your Digital Twin — SDK and Canvas launches, LTI, and single sign-on, which lands people on the first entry. Any site not on the list is rejected, and an empty list refuses every launch — this is what stops a random third-party site from dropping your assistant into their page.
Treat this list as a security boundary. Only add origins you control or trust.

​
Adding an authorized URL

1

Open the Integrations section

On the Digital Twin editor’s Configuration and Integrations tab, scroll to Integrations → Embedding & LTI, where you will find Public Authorized URLs.
2

Add the URL

Type the URL in Enter new item and select Add. Include the scheme (https://) and host; the path is ignored.
3

Save the Digital Twin

The new URL is live as soon as you save.

​
Matching rules

Hosts match by hostname suffix. Adding https://example.com authorizes that host and every subdomain underneath it (single- or multi-level). Adding https://app.example.com authorizes only that host and anything deeper. No wildcard syntax is needed.
The match is host-only — Pria compares the hostname, not the scheme, port or path. The React component and avatar embeds are stricter: they need the exact origin (scheme, host and port). Pick the most specific host that covers your real launch surfaces; broader entries authorize more.

​
Public ID

Each Digital Twin has a Public ID — an opaque identifier safe to share with anyone. The SDK and the branded login link use it to identify which Digital Twin to launch (the guest link uses the Convo Web Access Link instead). Where the twin’s internal id is private (never put it in a URL), the Public ID is designed to be visible.
1

Find it

Copy Public ID from the editor’s Configuration and Integrations → Instance Details (or Instance Settings → General).
2

Use it in an SDK launch

Pass it as the publicId option when initializing the SDK on your site. See the SDK integration guide.
3

Use it in a branded login link

Share https://<your-pria-host>/login?brandingId=<publicId> to send users to a login page branded for your Digital Twin — after signing in, members land directly on it.

​
Custom domain (white-label)

Running Pria on your own subdomain — assistant.yourcompany.com rather than the default Pria host — is a hosted setup we configure for you. Contact the Praxis AI team at humans@praxis-ai.com to request a custom domain. We will coordinate DNS, the TLS certificate, and the routing.

​
Emails from Pria

​
string
Used as the From name on transactional emails Pria sends on behalf of your Digital Twin.
Pria’s emails come from a do-not-reply address that is platform-managed; replies are not read. Contact humans@praxis-ai.com if you need a white-labelled sender domain.

​
Favicon and app icons

The Digital Twin’s logo doubles as the favicon and the touch icon for users who add the Digital Twin to a home screen. Upload a single square logo with reasonable contrast against both light and dark backgrounds and you are done — Pria renders the appropriate variant for each surface.
