Build

Create your own avatar, give it a persona and a voice, and follow recipes for a voice agent and for Claude and Cursor. Then browse the example gallery.

Create

Make the avatar yours: its face, its persona, its voice.

• Create your own avatar

  Turn a portrait, a voice sample and a prompt into your own avatar: what to upload, how to write the persona, and the API call.

• Persona

  Write the system prompt that gives an avatar its personality, with the CO-STAR framework and a worked example.

• Voices

  Every agent speaks every language on bitHuman's built-in voice pipeline, included in the voice chat rate — or bring your own OpenAI, Grok, ElevenLabs, or Cartesia key for premium voices.

• Gestures (Essence 1)

  Play a named gesture (wave, nod, clap) on an avatar exactly when your code asks, on a cloud avatar or a self-hosted one.

Recipes

End to end, from an empty folder to a working result.

• Voice agent

  A voice avatar on your own computer: LiveKit runs locally, OpenAI Realtime listens and speaks on your own key, and the bitHuman avatar renders on your CPU. One CLI command, or a short Python agent.

• Website widget

  Add a floating, talking avatar to any website with one script tag: the floating widget or the chat widget, every option, React and Next.js, and your own persona and model with no server.

• Companion app

  An AI companion in your iPhone, iPad or Android app: a photoreal Essence 2 avatar that renders on the phone and speaks the replies your own voice stack produces.

• Kiosk on a Linux PC

  A live avatar full screen on a standard Linux PC with no GPU: the CLI renders it on the CPU, Chrome shows it in kiosk mode, and visitors talk to it.

• Talking video

  Turn one audio file into an MP4 of your avatar speaking it: with the CLI or Python on your own machine, CPU only on Linux, or with one REST call to the bitHuman cloud.

• Claude & Cursor (MCP)

  Let Claude, Cursor and other MCP clients drive bitHuman as tools: create agents, speak, embed, render. The server is built into the CLI (bithuman mcp).

Examples

Complete apps you can clone and run, with a recording of each.
