A swarm is a group of synchronized Matrix accounts that operate as a single logical identity. Each swarm member (account) joins rooms together, shares encryption keys, and can send or receive messages on behalf of the swarm. This setup allows users to continue communicating even if one or more home servers become unavailable.
Motivation (click to reveal)
Matrix currently ties user availability and message continuity to the uptime of a single home server. If that server goes down, users lose access to their rooms, and communication is interrupted. Swarms solve this by creating redundant, synchronized identities capable of message failover and shared state synchronization.
Working across several chats and need to keep important messages in one place? Favourites let you collect messages from any room into named lists. Create lists (e.g. "London Project", "Meeting notes"), turn on select mode in any chat, choose the messages you care about, and add them to one or more lists. Each list is a timeline of links to those messages: when you open a list, Masi resolves each link and shows the actual message content, so you get a single view of your saved snippets from different conversations - like a shared board of references without leaving the app.
Turn any favourites list into a playlist: a fullscreen, auto-advancing slideshow. Hit play on a list (from the sidebar or the list’s header) to step through its items-images and, if you enable it in settings, text messages-with configurable durations. Handy for review sessions, standups, or any time you want to cycle through saved content hands-free.
Use the Calendar room to schedule messages for later. Pick a destination room, choose a date and time, write the message, and optionally attach images or videos. Masi stores scheduled items in a private per-swarm Calendar room, then sends them when the app is running and the swarm has access to the destination room. Failed sends are visible in the calendar and can be retried or reset
