Description: Ask ChatGPT about your DataFast traffic, revenue, funnels, and custom goals, with interactive charts and access limited to the websites you choose.

# ChatGPT app

Ask ChatGPT about your DataFast analytics and see interactive charts inside the conversation. Explore your traffic, find your best revenue sources, and follow up on a result without exporting data or writing queries.

**Developer preview:** you can connect DataFast as a custom app in ChatGPT. It is not yet published in the public directory. [See how to connect](#connect-datafast).

*An example from the developer preview: daily visitors and revenue for a selected website and date range.*

## What you can do

- **Chart traffic and revenue.** Ask “Show visitors and revenue for my website over the last seven days.” Explore the chart, refresh it, or open the website in DataFast.
- **Compare marketing channels.** Ask “Which referrers brought in the most revenue this month? Show a bar chart.” You can also compare pages, campaigns, countries, and devices.
- **Explore conversion funnels.** Ask “Show my signup funnel and where visitors drop off.” The app uses the funnels you have set up in DataFast.
- **Inspect custom goals.** Ask “List the custom parameters recorded for my signup goal, then break down completions by plan.” Use a goal and parameter your website actually tracks.
- **See active visitors.** Ask “Show where visitors are active right now.” The map groups approximate locations from the last ten minutes.

Choose the website and date range in your request. Revenue, goals, and funnels reflect the data you have connected or recorded in DataFast; your existing plan limits still apply.

## Connect DataFast

You need a DataFast account with API access and a ChatGPT account or workspace that allows custom connections in developer mode.

1. In ChatGPT, open **Settings → Security and login** and enable **Developer mode**. Availability depends on your account and workspace policy.
2. Open [ChatGPT Plugins](https://chatgpt.com/plugins), select the **+** button, and name the connection **DataFast**. Add a short description, such as **Website analytics**.
3. Enter the server URL below and choose **OAuth** if asked for an authentication method.

```

4. Sign in on **datafa.st**, choose the websites and permissions to share, and select **Allow access**. Start with read permissions for analytics. You do not need to create or paste an API key.
5. Start a new ChatGPT conversation, enable DataFast from the tools menu, and try one of the questions above.

See [OpenAI's connection guide](https://developers.openai.com/plugins/deploy/connect-chatgpt) for the current setup screens and availability.

## You choose what to share

ChatGPT can access only the websites and permissions you approve. DataFast checks your current website membership, team role, and plan on each request. Newly added websites are not automatically shared.

Analytics works with read permissions. You can optionally grant write permissions for supported actions, such as adding chart notes or managing goals. Ask ChatGPT to explain and confirm changes before making them. The app cannot manage API credentials, delete websites, or connect payment providers.

The results you request are shared with ChatGPT. Custom goal parameters and notes can contain information you recorded, so choose permissions accordingly. Your DataFast password, dashboard session, and existing API keys are not shared, and chart widgets do not receive connection tokens.

Manage or revoke access in [Connected apps](/oauth/connections). Revoking access blocks future requests and token refreshes; it does not delete data already shared with ChatGPT.

## How it connects

The app uses [MCP](/docs/mcp-introduction) to call DataFast tools, with OAuth for sign-in and access approval. The charts add an interactive view of the same authorized analytics. See the [OAuth reference](/docs/mcp-oauth) for exact permissions and data handling.
