Bring AI to life
Turn any photo into a real-time video avatar.
Create AI characters with vivid voice and lifelike presence. Build talking avatar videos and illustrated multimedia books. Real-time lip-synced avatars that run fully on-device — from Raspberry Pi to iPhone to NVIDIA GPU — private by design, so your audio, video, and prompts never leave your hardware.

What you can build
- Real-time avatars — Audio in, lip-synced animated face out at 25 FPS.

- Shareable multi-avatar apps — Embed bitHuman agents anywhere.
Runs everywhere
Python SDK (pip install bithuman), Swift SDK for Apple devices, REST API, and a no-code web dashboard. The new Essence 2 models bring photorealistic humans and Expression 2 animates cartoons and animals with lifelike motion; both self-host on CPU. Classic Essence runs on any CPU; classic Expression 1 is GPU-only. Every session — cloud, self-hosted or on-device — authenticates against api.bithuman.ai with a once-per-minute billing heartbeat.
Private, on-prem, and cost-effective
Render self-hosted or on-device and your audio, video, and prompts stay on your own hardware — only a once-per-minute billing heartbeat leaves it. Deploy on the bitHuman cloud, self-hosted, or on-premise; offline licensing for fully disconnected sites is coming soon. Self-hosted serving is half the cloud rate — from 1 credit per minute.
