Use bitHuman in ChatGPT

Add bitHuman characters to ChatGPT for talking clips and live voice chats.

View as Markdown Open in ChatGPT Open in Claude

Add bitHuman to ChatGPT and its AI characters speak in your chat: ask one to say a line and a short video clip plays, or open a live voice conversation with it. You don’t need a bitHuman account. The short version, with a QR code for your phone, is at bithuman.ai/mcp.

What you’ll build

A ChatGPT chat where you can:

  • see bitHuman’s characters, with a picture of each
  • have one say your exact words (3 to 200 characters, about 15 seconds) as a video clip you can download or share
  • talk to one live, by voice, for up to a minute

Steps

3 steps

  1. Turn on developer mode

    Until bitHuman is listed in ChatGPT’s app directory, you add it as your own app. This needs a Plus, Pro, Business or Enterprise plan.

    1. Open your profile menu, then Settings → Apps → Advanced settings.
    2. Turn on Developer mode.
    Expected

    Settings → Apps shows a Create button.

  2. Add bitHuman

    1. In Settings → Apps, choose Create.
    2. Name: bitHuman. MCP server URL: https://mcp.bithuman.ai/mcp. Authentication: No authentication.
    3. Tick I trust this application, then Create.

    ChatGPT moves these menus from time to time; if a label differs, look for Apps and Developer mode in Settings.

    Expected

    bitHuman is listed under Settings → Apps.

  3. Try it

    Start a new chat, choose +, pick bitHuman, and ask:

    • “Show me the bitHuman characters.”
    • “Make Gio say: Welcome to the team, everyone!”
    • “Have Wise Pup explain photosynthesis in one sentence.”
    • “Let me talk to Pip live.”
    Expected

    A row of character cards appears in the chat; asking for a line plays a short clip of that character saying it.

How it works

ChatGPT writes the words; bitHuman voices them and animates the character on its own servers, then the clip plays in the chat. A live conversation opens in ChatGPT’s large view; closing it ends the call. Each person can make 10 new clips a day, and asking for the same line again replays it. Clips are kept for 7 days. What is stored, and for how long: bitHuman in ChatGPT and Claude.

Make it your own

The ChatGPT app speaks only as bitHuman’s own characters. To use your own avatar or voice, create an agent and build with the CLI’s MCP server or the SDKs.
