# Connect ChatGPT (web)

This page is for **ChatGPT in the browser** (chatgpt.com) and regular chat in the ChatGPT desktop app. **Codex** – including **Codex CLI** and the **Codex** tab in the ChatGPT desktop application – uses a different setup. See [Connect ChatGPT / Codex](https://chartbuddy.io/hub/docs/connect-mcp/chatgpt-codex.md).

::: warning Chartbuddy Hub MCP is not available here yet
Chartbuddy Hub connects over **local stdio MCP**. ChatGPT in the browser and regular desktop chat cannot reach a local Chartbuddy Hub process, and we do not ship a **remote MCP** endpoint yet – so regular ChatGPT cannot connect to Chartbuddy Hub MCP today.

## What you can use instead

| Option | Best for |
|--------|----------|
| **[ChatGPT / Codex](https://chartbuddy.io/hub/docs/connect-mcp/chatgpt-codex.md)** | Full Chartbuddy Hub MCP in Codex CLI or the desktop **Codex** tab |
| **[Embed docs](https://chartbuddy.io/embed/docs/getting-started.md)** | Charts inside ChatGPT conversations via HTML artifacts and the `@chartbuddy.io/embed` widget |

For Embed, start with [`llms.txt`](https://unpkg.com/@chartbuddy.io/embed/llms.txt), then [Getting started](https://chartbuddy.io/embed/docs/getting-started.md) and [Visual QA](https://chartbuddy.io/embed/docs/quality-assurance/visual-qa.md) in the Embed docs.
