Simli

What is Simli?

Simli provides real-time video avatars that developers add to an app or website in minutes. The avatars have lifelike facial expressions, support face cloning, and use Gaussian-based emotive facial models for realism.

Key capabilities of Simli

• Real-time avatars: high-resolution, lifelike expressions
• Face cloning: create an avatar from a face
• Low-latency speech-to-video: under 300 ms
• Emotive models: Gaussian-based facial models
• Use cases: sales assistants, chatbots, interview simulations, language training and customer support

How Simli works

Simli's speech-to-video component renders the avatar from audio in under 300 ms. In a typical agent pipeline, speech-to-text takes about 100 to 500 ms, the LLM about 250 to 450 ms and text-to-speech about 250 to 1,200 ms, so the avatar is one stage in that chain. Documentation is at docs.simli.com.

Who uses Simli?
