Sentifyd AI Avatars Overview
Introduction to Sentifyd 3D AI avatars and their conversational and agentic capabilities
Sentifyd empowers you to deploy intelligent, real-time 3D AI agents—fully animated avatars capable of natural, voice-driven conversations. These interactive 3D agents go beyond traditional chatbots by combining Retrieval-Augmented Generation (RAG), dynamic motion, and customizable tool integration.
With Sentifyd, your 3D AI agents can:
Understand and respond to user input in real time using natural voice and language.
Express themselves through lifelike gestures, movement, and tone for an immersive user experience.
Access and reason over your own content—such as manuals, FAQs, or internal documents—while maintaining strict privacy and security protocols.
Connect with powerful tools like MCP servers and more, enabling task execution and contextual awareness.
These agents can be easily embedded into your website or application, offering users a compelling, intelligent interface that feels truly alive.
Core Capabilities
1. Expressive & Adaptive AI Personalities
Embodied Communication Sentifyd 3D AI agents communicate not just with words, but with presence. Each agent mirrors human behavior through natural body language—nodding, gesturing, and mood-aware animations that convey emotions like curiosity, empathy, or excitement. Realistic facial expressions enhance every interaction, making conversations feel intuitive and emotionally resonant.
Voice + Personality Fusion Select from a diverse set of multilingual voices to match your audience. Go further by training each agent’s voice and personality to align with your brand—whether warm and approachable, sharp and professional, or lively and fun.
Contextually Intelligent Responses Every agent is powered by Retrieval-Augmented Generation (RAG), enabling accurate, context-aware replies grounded in your documents, policies, manuals, or any custom knowledge base. This dramatically reduces hallucinations and ensures reliable, high-quality answers.
2. Real-Time Interaction
Flexible Interaction Modes Instantly switch between modes based on your user’s needs:
Avatar Mode: Engage through a fully animated 3D AI agent with synchronized lip movements and real-time voice captions—for both the agent and the user. Barge-in mode can be enabled to have natural conversations.
Chat Mode: Prefer a simpler interface? Switch to streamlined text-based interactions without the animated avatar.
Full Command & Customization Control your AI agent effortlessly using voice or text commands. Dynamically:
Adjust the camera view (full-body, upper-body, or head-only)
Toggle captions on or off
End or restart conversations
Seamlessly switch between interaction modes at any time
Sentifyd gives you the power to create fluid, adaptive experiences that fit any environment—whether embedded on a website or integrated into an app.
3. Privacy-First Design
Zero Data Retention by Default Sentifyd is built with user privacy at its core. No conversation transcripts or logs are stored on Sentifyd's servers. We only keep the conversation hot for a couple of hours for context management and easier resuming. Our industry trusted suppliers of LLM models may also keep the conversations for a short period for legal purposes. We do not train our models or application using your data. End users retain full ownership of their data and can download their conversation transcript during a conversation. User personal data might be collected with their consent during a conversation to perform tasks such as sending customer support requests.
Built-In Safety & Compliance Sentifyd agents operate within secure, AI-guarded environments. Through integrations with leading AI platforms, all interactions are protected by advanced safety mechanisms. Harmful, unsafe, or non-compliant prompts are proactively detected and blocked, ensuring every conversation stays within ethical and legal boundaries.
4. Customizable Engagement
Create a Custom 3D Avatar Start by designing your AI agent’s appearance using integrated avatar creators like ReadyPlayerMe or Avaturn. Customize everything—from hair and clothing to accessories—to reflect your brand’s unique style and tone.
Infuse Personality & Intelligence Upload your own content—such as product manuals, policies, FAQs, or internal docs—to build a custom knowledge base that powers accurate, context-aware responses. Define persona traits, preferred tone, and sample dialogues to shape how your agent thinks, speaks, and interacts—whether professional, playful, empathetic, or anything in between.
Customizable Avatar Widget Customize the avatar widget to match your brand, set the widget interface language to one of six supported language, and adapt how the widget is installed in your website. You can also change the colors, logo, add a company name, and other styling & branding options. Please check the installation guides.
Your AI agent doesn’t just look the part—it acts the part, fully aligned with your brand identity and user needs.
5. Advanced Tools
Equip Your Agent with Powerful Tools
Give your 3D AI agent more than just a voice—give it the ability to act. Sentifyd agents can be connected to custom tools that extend their functionality, allowing them to solve real problems, fetch live information, and even interact with external systems on your behalf.
Out-of-the-Box Tools:
Tools to control the avatar itself and the chatbot user interface
Web Search Agents can safely browse the internet in real time to provide up-to-date answers, going beyond your internal data sources when needed.
Send Support Requests When a user needs human help, the agent will collect contact information (e.g., name, email, phone) and instantly submit a support request to your team—ensuring seamless escalation.
Connect Custom Tools with MCP Servers
For advanced integrations, Sentifyd supports MCP (Modular Command Processing) Tools, allowing your agent to interface with any backend service or external API in real time.
What MCP Tools Enable:
Execute Streamable HTTP or SSE-based actions directly from within a conversation
Get live responses from custom services (e.g., booking systems, internal APIs, IoT devices, CRMs)
Use custom headers and secure tokens to authenticate connections to MCP servers.
MCP Tool Configuration Includes:
Connection Type: Streamable HTTP or SSE (legacy)
Endpoint URL: Your custom API or service endpoint
Headers (JSON): Securely pass tokens or metadata (e.g.,
{"Authorization": "Bearer TOKEN"})
With MCP servers, your 3D AI agents become fully agentic—capable not just of understanding but of doing. Automate tasks, connect with live systems, and give your users real results in the flow of conversation.
How It Works: User Experience
Engage the Agent Users begin by clicking or tapping to activate your 3D AI agent—instantly met with a lifelike, responsive avatar ready to assist.
Speak or Type Naturally Whether through voice or text, users can ask questions, give commands, or hold a conversation just like they would with a real person.
See the Agent in Action The agent responds in real time, using voice, gestures, facial expressions, and live captions. It can also perform actions—like retrieving data, searching the web, or submitting a support request—based on the conversation.
Adjust the Experience Users can switch between avatar and chat-only modes, toggle captions, and adjust the avatar's view (head-only, upper-body, or full-body) for their preferred experience.
Wrap Up & Retain the Conversation At any point, users can end the conversation. If enabled, they may also download a transcript of the interaction for their records.
