Fast Party is an intelligent event planning and management platform for everything from an intimate dinner or birthday to a 500-person conference. Whatever you’re planning, it comes down to two things: which event type you choose, and which features you switch on. Whether you’re a host putting together a private gathering or an organizer running meetings, conferences, and exhibitions, the same platform handles the details — guests, invitations, schedules, food preferences, tasks, vendors, and more — all in one place. Fast Party works on the web at https://app.fastparty.ai, or download the app on iOS or Android mobile platforms.

Meet Antsy, working behind the scenes Antsy is Fast Party’s built-in intelligence layer. It works quietly in the background — smart nudges, reminders, and predictions that keep your event on track, so nothing slips through the cracks as the date approaches. Or plan through conversation, with Claude or ChatGPT Fast Party connects to both Claude and ChatGPT through our MCP server. Once configured, you can manage your entire account through natural conversation — create events, invite guests, build agendas, assign tasks, and more, without opening the app. Just tell the AI what you need.

​
Event Types:

Two event types, one optional layer Almost everything in Fast Party builds on three ideas. Understand these and the rest of the docs will make sense quickly.

Regular Event

An invitation-based event. You control the guest list, and invited guests RSVP directly. No registration queue, no approvals. Best for birthdays, dinners, weddings, family gatherings, meetings, and private functions.

Registered Event

A registration-based event. You open a registration link, and people request a spot — you approve or decline each one. Supports ticket types, capacity limits, and payments. Best for conferences, exhibitions, ticketed gatherings, and any event where you vet attendees.
And the layer that sits on top of both:

My Circles — make any event recurring

A Circle is a saved group of people. Add your members once, then run event after event with the same group without re-entering names. This is how a one-off event becomes a recurring one — a monthly book club, a quarterly townhall, or a conference that returns every year. Either event type can live inside a Circle.
