PostHog in ChatGPT and Codex: Read an Onboarding Funnel
Use the connected PostHog app to inspect a two-step onboarding funnel. Confirm event names, project and dates, then report the counts and conversion rate.
中文Setup for ChatGPT / Codex (requires the connected PostHog app)
ChatGPT or Codex with the PostHog app available and authorized for a demo project. For this example, use synthetic onboarding events and an account with read access.
- Look for PostHog among the available apps or plugins in your workspace and connect it through the PostHog sign-in flow.
- Select the demo organization and project during setup. Start a new session if the app does not appear in the current one after connecting.
- Open a conversation with PostHog available. Tell the assistant which demo project to query and ask it to confirm the event names before calculating the funnel.
Example task
Read the demo PostHog project only. Confirm that tutorial_started and tutorial_completed exist, then show the ordered funnel from the first to the second over the last seven days in the project timezone. Return the distinct-person counts and the percentage who completed after starting. If the demo fixture has five starters and three completions, show how to check the percentage. Leave dashboards and settings untouched.Expected result
The response identifies the verified project, dates and event names. Five starters and three completions equal 60% in the example fixture. If either event is absent or nobody started, the response explains the missing input or denominator without guessing a percentage.

Frequently asked question
What should I check if a PostHog funnel has fewer events than expected?
Confirm the exact event names, project timezone, date range, and filters. Check how the funnel deduplicates people and whether the second event must follow the first within a conversion window.
