Upbuild
Written by Uptimal, the team that builds and operates Upbuild and runs marketing analytics for multinational clients across the globe. Everything below reflects how Upbuild actually behaves in production.
ChatGPT plus the GA4 Data API is the fastest route from “how did the site do” to an actual number with context. Current 2026 steps, plugin era:
The ChatGPT path
ChatGPT needs Developer mode first: Settings, Security and login, switch on Developer mode. Then Settings, Plugins, Browse plugins, hit the + button and fill the New Plugin dialog: name Upbuild, Connection on Server URL with https://connector.upbuild.app/mcp, Authentication OAuth, tick the custom-server notice, Create. The setup guide shows every screen.
Sign in with Google or Microsoft, then approve with the Google account holding property access; Viewer level suffices, and every property you can see becomes queryable.
Prompts that earn their keep
- “Write Monday’s traffic summary: sessions, key events, top channels, week over week.”
- “Anything anomalous yesterday versus the trailing 28 days?”
- “Top products by revenue this month, with conversion rate.”
Good to know
Thresholding and sampling can shape GA4 numbers, and Upbuild flags both rather than papering over them; platform depth is in the GA4 guide.
Ask your ad platforms directly, in Claude, ChatGPT, Copilot Studio or Gemini Enterprise.

Does this work on free ChatGPT?
Custom plugins require a paid plan (Plus and up) with Developer mode enabled on the web.
Can it query multiple GA4 properties in one chat?
Yes; ChatGPT can enumerate accessible properties and compare them explicitly when you ask.
