Real-time, location-based chatrooms.

Drop a Pin

Place a chatroom on the map. Set its radius and time limit, and only people inside that area can see and join it while it lasts.

Join Nearby Chats

Chatrooms appear on the map and pulse when there's activity. Simply tap a chatroom pin to join the conversation with your neighbors.

Duration

Every chatroom you create is ephemeral. You decide exactly how long your chat remains active. Once the timer runs out, the chat disappears automatically.
