Why connect Mixpanel to ChatGPT?
Product updates usually mean screenshots of Mixpanel boards pasted into a doc. With Lemonado, ChatGPT reads your events, funnels and retention live, so it writes the update from this week's numbers and can add which campaigns brought the new users.
All your Mixpanel data
Every event you track, with its properties, ready to ask about.
Always today's numbers
Retention by signup week, synced from Mixpanel automatically, so answers use today's numbers.
Connect all your tools
Questions like "Which channel brings active users?" use Mixpanel and PostHog, GA4 at once.

Ask ChatGPT about Mixpanel
Start a new chat, type @ and pick Lemonado. Sign in to Lemonado when ChatGPT asks. Try "@Lemonado Write this week's growth update from Mixpanel: signups, activation, week 4 retention and anything unusual, in five bullets." Or ask: "Which campaigns bring active users?" or "Why is activation down?"
Good to know
- Your ChatGPT account and workspace settings decide whether you can add custom MCP servers. Workspace admins can turn it off.
