Overview

Group chats outgrow group chats.

Chatter started as a question: what if the running club, the apartment block and the weekend trek group didn’t have to live in one endless scroll? This concept gives every community a structured home — announcements that stay visible, side threads that don’t derail, and plans that survive the chat.

Designed end-to-end as a portfolio concept, tested with five community organizers.

Challenge

Structure without sterility.

Forums are organized but dead; chats are alive but chaotic. Organizers wanted both: the energy of chat with a memory. The design problem was hierarchy — how much structure can you add before a chat stops feeling like a chat?

  • Announcements pinned above the fray, always glanceable
  • Side threads that branch visually, then fold back
  • Events with RSVPs that don’t need a separate app
Approach & solution

A chat with a memory.

Three tabs carry the whole concept: Chat for the live pulse, Threads for anything worth keeping, and Plan for events and polls. A violet-on-dark visual language keeps night-time scrolling easy, and voice notes get auto-transcripts so nobody has to play a 4-minute ramble.

Organizers in testing planned a real trek using only the prototype — then asked when they could download it.
