What is Prism App?
Your system, together. Prism helps plural systems track fronting, chat between members, log sleep, build habits, run polls, and keep shared notes — all encrypted end-to-end, synced across your devices.
See who's here. Log who's fronting with co-fronters, confidence levels, and notes. See your system's full timeline — who was out, when, and for how long.
Talk to each other Share photos, send voice notes, drop GIFs into the conversation. Reactions, replies, and direct messages. A space for your system to actually talk.
Decide things together Polls with anonymous voting, multiple choice, and expiration. When your system needs to make a decision, actually ask everyone.
Build routines together Habits with streak tracking and assigned members. Sleep logging with quality ratings. Statistics that show the shape of your system over time.
Bring everything with you. Already tracking with Simply Plural or PluralKit? Import your members, custom fields, and history in a few taps. You can even keep PluralKit in sync, so fronting changes flow both ways — and your proxy tags work in Prism's chat too.
And so much more... Statistics, sleep, profiles, notes, reminders, groups, custom fields, theming, comments...
Your system is yours. Not even we can read your data. Everything is encrypted on your device before it goes anywhere. The server stores scrambled data, and we literally cannot see what's inside.
Built by a plural system, for plural systems. Prism is an independent project — no VC funding, no corporate parent, no investors to please. Just software made by people who actually need it.
Prism uses AI for development. Prism is written by a plural system that actually uses it every day. We use AI coding tools (local models and hosted ones) to help us ship faster. The security architecture, design decisions, interface, the things that make this app what it is are ours. The encryption is fully auditable and open source regardless of what tools wrote it, and we hope the app's quality stands on its own.
