Step 01
Choose your persona
Pick from 14 built-in AI roles, each with a distinct voice, expression set, and conversation style. Or build a custom chat persona from sliders and a description, or use the AI builder to generate a live avatar persona from a single sentence.
- 14 pre-built personas covering interviews, medical, language, and more
- Each persona has tuned defaults for mood, sassiness, and formality
- Create your own from a description in seconds
Step 02
Configure your session
Set the conversation language, adjust personality sliders, and add free-text context or upload a document so the persona understands your specific situation. Everything is optional; sane defaults are already set.
- 30+ languages supported, switch per session
- Five personality sliders: mood, sassiness, formality, empathy, hostility
- Upload PDF, DOCX, or TXT as session context
Step 03
Speak in real time
Talk to a photorealistic avatar with lip sync and facial expressions. ElevenLabs TTS streams sentence-by-sentence so responses feel immediate. Every conversation is saved to your session history.
- Photorealistic avatar with matched lip sync over WebRTC
- Responses stream in real time with no delays
- Full conversation saved to your account history

What languages are supported?
Over 30 languages are supported for text chat and TTS voice responses. The language selector persists across sessions and can be changed at any time.
Can I create my own persona?
Yes, two ways. The chat persona builder lets you set a name, role, description, personality sliders, and a voice. The AI avatar builder lets you describe a character in plain English; Gemini generates the system prompt and a live Beyond Presence avatar agent is created automatically.
