peer-to-peer
social platform.
Share posts, photos, and messages directly with friends. Built-in protection against spam and abuse. All content is encrypted end-to-end with no central servers.
How it works
Install the app on your desktop or mobile device. On first launch, a 24-word recovery phrase is generated. All your keys are derived from this phrase, and messages are encrypted locally before being sent peer-to-peer.
