Personalization (Digital Twin)

The Personalization section of the admin editor

​
Name & Avatar

The name people see in conversations, the gallery and across the interface. Left blank, it is Pria. Pick a name that reflects the twin’s persona or expertise (“Professor Adams”, “Campus Guide”).
The twin’s avatar. Click the picture itself to upload a new one — there is no separate “Upload” button. Hover the picture for the camera overlay; the small × that appears on hover removes it. The picker crops a square image to a circle, so start from a square image at least 256 × 256 px with the subject centred. Left blank, the Pria logo is used.
An animated avatar shown during conversations. Left blank, the static picture is used.
The image behind the conversation area in light mode. Click the preview thumbnail to upload a new one (from a file or your webcam). The picker crops to widescreen 16:9, so start from a landscape image at least 1920 px wide.
The same, for dark mode, so both themes look intentional. Left blank, the default dark background is used.

​
Content & Behavior

A description of the twin’s purpose, expertise and abilities, shown in the gallery. The label shows its length in characters.Select Generate to have Pria write it from the twin’s instructions and its active assistants. Update those first, then generate, for the most accurate result.
Shows the About text and the twin’s picture on the welcome screen instead of the default welcome content.
The twin always speaks as its character: questions about what it can do are answered in its own voice, without platform guides or tool lists. A twin given instructions for the first time starts with Persona mode on.
The instructions that shape the twin’s personality, expertise and behaviour — the most important setting for how it talks to people. The label shows their length in characters.The Onboarding Questions interview can write a first version for you. For methods and templates, see Crafting Digital Twin Instructions.
Adds a separate block of rules, Guardrail Instructions, right after the instructions in every conversation, typed or spoken — for what the twin must always or never do. Load default template gives you a starting point when the box is empty.

​
UI & Appearance

A minimal, chat-only interface without the profile menu, sidebar or Digital Twin switching. Use it for public twins embedded in a website.
Removes the copy and paste actions on answers for standard users — useful when the twin handles confidential content. Admins keep them.
Hides the microphone that lets standard users record spoken notes into their personal IP Vault. Admins keep it. Audio Notes is also hidden whenever Guest UI or Disable File Upload for Users is on. See Audio Notes.
If your Digital Twin existed before Audio Notes was introduced, this box was ticked for it so the new microphone wouldn’t appear without warning. Untick it to offer Audio Notes. Newer Digital Twins have it on already.
Custom CSS for your Digital Twin’s interface — fonts, colours, layout. The View template… link next to the label opens a starter template with every available class. For example:
See UI Customization for the full template reference.
— User Directed — (each person picks), Dark Mode or Light Mode for everyone.
A branding key, which applies custom branding to the Digital Twin, is set by the Praxis AI team: contact humans@praxis-ai.com.

​
AI Models

Each dropdown lists the models of the platform catalog suited to that job. — Default — follows the platform default. See AI Models for which model answers when several are set, deprecated models and reasoning effort.

​
Custom Models

Lists the Digital Twin’s active custom AI models. You add them in Admin › AI Models (see Bring Your Own AI Model). While a custom model is active for a job, that job’s dropdown below is hidden.

​
Conversation & Reasoning

Conversation Completion Max Tokens: Claude models need 4,000 or more to think before they answer. Models reached through Amazon Bedrock reserve about five times this number against a shared usage limit, so a very high setting can make requests fail with “Too many tokens” when many people chat at once. If that happens, lower it or set it to Unspecified.
Extended Context costs more per token from Anthropic. Turn it on only when the twin must read very large documents or keep very long conversations.

​
Convo (Live Voice & Avatar Calls)

Shown when Enable Convo is on (see Configuration). The full provider guide is Realtime Voice & Avatars. Speech-to-Speech Model decides the call experience. Anam models show a video avatar; the others are voice only: The fields below the model depend on the provider: Avatar look and greeting settings for Anam (placeholder image, introductory message and more) are in the Configuration and Integrations tab; see Realtime Voice & Avatars.

​
Subagents

Pins the model, and the effort, for each subagent role. Leave them on the platform default unless you have a reason to change one. The switch that makes subagents available, and their budgets, are in the Configuration and Integrations tab. See Configuration.
