Event analytics

Query events, track user behavior, and analyze funnels and trends through natural language.

Feature flags

Create, update, and evaluate feature flags — control rollouts and target specific user segments.

Dashboards & insights

Create dashboards, build custom insights, and analyze retention and funnel data.

Triggers

Automated triggers for PostHog are not yet available. Triggers will be added in a future update — check back soon.

Example use cases

Ask “How many users completed onboarding this week?” and the agent queries PostHog events, filters by date, and returns the count — no dashboard navigation needed.
Ask your agent to roll out a feature flag to 25% of users in a specific cohort. It updates the flag configuration and confirms the targeting rules are applied.
Ask “How is the new checkout experiment performing?” and the agent retrieves experiment statistics, calculates significance, and presents a clear summary of which variant is winning.

Troubleshooting

Verify the key was created at us.posthog.com under Settings → Personal API Keys. Make sure the key has the scopes needed for the operations your agent performs.
This integration connects to PostHog’s US cloud (us.posthog.com). If your project is on the EU cloud, disconnect this integration and connect PostHog (EU) instead.
Events may take a few minutes to appear in PostHog after being captured. If events are consistently missing, check that your PostHog SDK is correctly initialized in your application.
Check the flag’s targeting rules and rollout percentage. Use “Get flag details” to inspect the full configuration and verify the conditions match your expectations.
