Build and Deliver AI-Powered Virtual Human Interventions
BABY Platform lets researchers and clinicians design configurable virtual character conversations and deliver them to participants — no engineering team required.
Design rich conversational experiences with AI characters — scripted, open-ended, or patient-simulation — and deploy them to any participant with just a link.
Realistic Virtual Characters
Attach a 3D avatar to your scenario. Configure voice, mood, and persona to create a believable interaction your participants will remember.
AI-Driven Dialogue
Power conversations with large language models. Use your own API key, attach a knowledge base, and shape the character's responses with a system prompt.
Built for Research
Participant sessions are tracked and logged. Export conversation transcripts as JSON or PDF, and integrate with survey platforms like Qualtrics via URL parameters.
How It Works
From scenario to session in minutes
A straightforward workflow designed so that researchers can build and launch without writing code.
1
Design Your Scenario
Use the step-by-step scenario builder to configure your virtual character — name, gender, mood, voice, and 3D model — alongside the conversation style and AI model you want to use.
2
Author the Conversation
Choose scripted (node-graph), open-ended (LLM-driven), or patient-simulation mode with objective tracking. Upload a knowledge base or craft a system prompt.
3
Share With Participants
Send participants a direct URL — optionally with a study ID parameter. Their session is logged automatically and you can download transcripts at any time.
Inside the Builder
Everything you need, in one place
A guided, no-code builder walks you from character selection to live deployment in just a few steps.
Step 1 — Character
Pick your virtual character
Browse or design photorealistic 3D avatars and filter by style. Your character's persona, voice, and mood are all configurable.
Step 2 — Conversation
Design the conversation flow
Author your system prompt on the left, then build a branching node graph on the right — or let the LLM drive it freely.
Step 3 — Template
Choose your interaction template
Chat panel view for a messaging-style experience, or character speaking view for a focused, immersive interaction.
See It In Action
What participants experience
Scenarios run in any browser, on any device — desktop, laptop, or mobile. No app installs, no friction.
Mobile
Fullscreen on any device
Participants interact with the character in a clean fullscreen view — no clutter, just the conversation.
Patient Simulation
Live objective tracking
Clinician training scenarios surface patient history and track learning objectives in real time alongside the chat.
Research
Multi-character scenarios
Deploy scenarios featuring multiple distinct virtual characters for richer, more complex research designs.
