# OpenAI

> Add HeyGen video generation to OpenAI ChatGPT via MCP. ChatGPT can script, render, and download AI avatar videos using the HeyGen toolset inside any.

If you've been bouncing between tabs trying to create AI-generated videos, there's a simpler way now. HeyGen — one of the more popular AI video platforms — has an app that plugs right into ChatGPT. That means you can script, customize, and generate a video without ever leaving the chat

## Step 1: Open ChatGPT

Head to [chat.openai.com](http://chat.openai.com) and log into your account.

## Step 2: Find the HeyGen App

Look for the [**Apps**](https://chatgpt.com/apps) section in the left sidebar (or in the GPT store area, depending on your interface version). Search for [**HeyGen App**](https://chatgpt.com/apps/heygen/asdk_app_69418aad55e08191aa5e437b649ca2e4). It should come up as an official integration.\\

## Step 3: Connect and Authorize

Click on the HeyGen app, then hit **Connect**. ChatGPT will ask you to authorize a connection between your OpenAI account and HeyGen. This is a standard OAuth flow — you're giving ChatGPT permission to talk to HeyGen's API on your behalf.

If you don't already have a HeyGen account, you'll be prompted to create one during this step. HeyGen does offer a free tier with basic access, though generation limits are tight. If you're planning to use it regularly, HeyGen paid plans unlock longer videos, more avatar options, and higher resolution output.

## Step 4: Generate Your Video

Once the app is connected, you just ask ChatGPT to make a video. Be specific about what you want — the more detail you give, the better the result.

For example, you might say something like:

> "Use HeyGen to create a 60-second product explainer video. Use a female avatar, professional tone, and include a brief intro and call to action at the end."

ChatGPT will handle the back-and-forth with HeyGen's system, and you'll get your video generated directly in the conversation.
