Show me all feature flags and which ones are enabled.

I found 8 feature flags. 5 are currently enabled: 'new-checkout' (80% rollout), 'dark-mode' (100%), 'ai-suggestions' (25%), 'beta-dashboard' (50%) and 'export-v2' (100%). 3 are disabled: 'legacy-search', 'old-onboarding' and 'deprecated-api'.

Create an annotation for today's deployment of version 3.2.0.

Done! I've created an annotation 'Deployed v3.2.0' pinned to today's date. It will appear on all relevant insights graphs so you can correlate any metric changes with this deployment.

Show me the profile of user 'user_12345'.

Here's the profile for user_12345: email is jane@example.com, signed up 3 months ago, last active 2 hours ago. Properties include plan:premium, company:Acme Inc, and role:admin. They've triggered 847 events including 120 pageviews and 45 purchases.

Log in to [**PostHog**](https://app.posthog.com), click your profile icon > **Personal API keys**, then **+ Create a Personal API Key**. Give it a label, select the required scopes and copy the key immediately — it won't be shown again after page refresh.
