# Prom > Hi, this is a cult. Come in. Every group has its own lore, rituals, and strange ways of being together. Prom is where all of it lives. This is not a place for an audience. It is a place for Members. Bring something of yourself. Take part in the ritual. Recruit the people you care about. Prom is a social app for groups with their own lore, from a friend group to a whole community, on iOS, Android and the web. A group gets a Circle: one chat for everyone, where each thing the group does together lives in its own Charm, made by asking Delphi. A Circle is at its best around 20 members, but communities of hundreds have run on Prom. Its own words for what it is: a cult, made of Circles, Charms and Delphi. ## Pages - [Home](https://www.prom.dev/): what Prom is and how to join the waitlist - [The Prom Manifesto](https://www.prom.dev/manifesto): "Join my cult."
