​
A

The top-level organizational entity in Praxis AI. An account can contain multiple Digital Twins (instances), manage billing, and oversee users across the organization. Accounts enable centralized credit management and administrative controls.
A role that provides scoped access to manage multiple Digital Twin instances within an Account. Account Manager access is configured by the Praxis AI team. Contact humans@praxis-ai.com to request this role.
A specialized capability that extends a Digital Twin’s functionality. Tools can perform specific tasks like searching Canvas, sending emails, generating images, executing API calls, or connecting to external services. They are configured per instance by administrators.
A reusable prompt template that guides how a Digital Twin responds to specific types of requests. Assistants can be personal (user-created), instance-level (shared within a Digital Twin), or account-level (shared across all twins). They automate workflows and ensure consistent, specialized responses.

​
B

An enterprise pricing option where organizations supply their own API keys for AI providers (OpenAI, Anthropic, Google, etc.). BYOK customers receive a 40% discount on standard pricing while maintaining direct control over AI usage costs through their existing provider agreements. See Plans and Credits for details.
An advanced enterprise feature that lets organizations connect their own API keys for multiple AI providers — OpenAI, Anthropic, AWS Bedrock, Google, xAI, Mistral, DeepSeek, and Cohere — to Pria’s Neural Engine. The Neural Engine routes requests across providers for automatic failover and cost optimization. See Switch to Praxis-AI Middleware for setup details.

​
C

The connection between Praxis AI and Instructure Canvas LMS. Available via LTI 1.3 protocol or Theme injection, allowing Digital Twins to appear directly within Canvas courses for seamless student and faculty access. Supports two-tier OAuth — a Student Access Token (read-only course data) and a Faculty Access Token (read/write for assignments, announcements, and grades).
An OpenAI-compatible REST endpoint that lets external applications interact with Digital Twins using the standard OpenAI SDK. Point any OpenAI-based app to Pria’s endpoint, use your Digital Twin’s Public ID as the model, and authenticate with a JWT — no other code changes required. See the Chat Completions guide.
A configuration that links a Digital Twin to external services or MCP (Model Context Protocol) servers. Connectors enable tools to interact with third-party services and data sources.
A session of back-and-forth dialogue between a user and a Digital Twin. Conversations maintain context and history, can be named for easy reference, and are stored for future retrieval.
Real-time speech-to-speech conversation with a Digital Twin, supporting 99+ languages. Powered by two voice providers: OpenAI GPT-Realtime (low-latency, client-side voice selection, full tool calling and MCP support) or ElevenLabs (custom voice clones, dashboard-managed voices). The voice provider is configured per-instance in Configuration. See Convo Mode for usage details.
The currency that powers AI interactions on the Praxis platform. Credits are consumed with each request based on complexity (typically 1-2 credits per interaction) and never expire. Credits can be pooled at the instance level or managed individually per user. Models that support caching (Claude, GPT-5) can reduce credit consumption by reusing previously processed context — savings are shown in the Dialogue Report Card. See Plans and Credits for pricing and Credit Optimization for saving tips.

​
D

An AI-powered virtual assistant with a unique personality, knowledge base, voice, and appearance. Digital Twins are the core product of Praxis AI—intelligent consultants available 24/7 to answer questions, perform tasks, and provide personalized support. Also referred to as an “Instance.”

​
E

Numerical representations of text that capture semantic meaning. When documents are uploaded to the IP Vault, they are converted into embeddings to enable intelligent vector search and RAG (Retrieval-Augmented Generation).
A third-party voice AI provider integrated with Praxis AI as an alternative real-time conversation provider. ElevenLabs supports custom voice clones and branded voice experiences for Digital Twins in Convo Mode. Selected per-institution via the Convo Voice Provider setting.
The process of adding users to a Digital Twin instance. Users can be enrolled individually, via CSV bulk import, or automatically through Canvas, Google Workspace, or API integrations. When integrated with Canvas or other LMS platforms, users are auto-enrolled on first access. See the Users admin guide for enrollment workflows.
