# Use bitHuman in ChatGPT

URL: https://docs.bithuman.ai/build/chatgpt

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

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](https://www.bithuman.ai/mcp?utm_source=docs&utm_medium=referral&utm_campaign=agentic-apps-launch).

## 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

### 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.

### 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.

### 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.

## Make it your own

The ChatGPT app speaks only as bitHuman's own characters. To use your own avatar or voice, [create an agent](https://docs.bithuman.ai/build/create-avatar) and build with the [CLI's MCP server](https://docs.bithuman.ai/build/mcp) or the [SDKs](https://docs.bithuman.ai/platforms).

## Troubleshooting

| Symptom | Fix |
|---|---|
| No Create button under Apps | turn on Developer mode first (Plus, Pro, Business or Enterprise) |
| bitHuman is missing from the **+** menu | open a new chat; check the app is listed in Settings → Apps |
| New features or characters don't show after an update | ChatGPT keeps the old version of the app: delete the bitHuman app in Settings → Apps and add it again |
| The live call stops | closing ChatGPT's large view ends it; a live call lasts up to a minute |
| "Daily limit reached" | 10 new clips per person per day; a line you already made replays |
