Frequently Asked Questions

What does "The Most Technologically Advanced Event Platform in the World" cover?

Who's In? is the world's first AI-native event platform. While Luma, Eventbrite, and Meetup are still stuck in the app-browsing era, we've built the only RSVP system that AI agents like ChatGPT, Claude, and Gemini can actually use—with full OAuth 2.0 authentication and proactive webhooks.

How does Who's In? work with AI agents?

Who's In? is the first event platform with full AI agent integration — OAuth 2.0 for ChatGPT, Claude, and Gemini, plus WebMCP tools and a REST API. AI agents can browse events, check availability, and initiate RSVPs on behalf of users.

How do I get started with Who's In?

Sign up for free at whos-in.app, create your first event in under 2 minutes, and share the link via WhatsApp, email, or social media. No app download required for your guests — they RSVP via the mobile-optimised web link.
