features
no accounts
A username and password deterministically derive your cryptographic identity. No phone number, no email, nothing to leak or get breached.
end-to-end encrypted
Ed25519 identity, X25519 key exchange, XChaCha20-Poly1305 messages. Only you and your peer can read a conversation — not us, not the network.
peer-to-peer
Messages, files, and calls travel directly between devices over encrypted WebRTC. No middleman server relays or stores your conversations.
all your devices
The same username and password unlock the same identity anywhere, and your devices sync conversations directly with each other — end-to-end encrypted, no cloud copy.
files, voice & video
Share files and make voice or video calls — encrypted, device to device, scoped to the conversation they belong to.
group chats
Encrypted groups with reactions, edits, replies, and receipts. Group keys rotate automatically when membership changes.
shared folders
Share a folder with exactly the contacts you choose. They browse and pull files straight from your device — no upload, no third-party storage.
verified contacts
Keys pin on first use, and a safety number lets you verify a contact out-of-band — so you know exactly who you're talking to.
your own AI peer
Run the voidmesh agent — a private AI powered by Hermes (Nous Research) that joins the mesh as a peer and answers only to you. Chat with it, send it files, even voice-call it — all end-to-end encrypted.
how it works
Dashed = discovery: nodes gossip each other's URLs and the peer roster, then introduce peers. Solid green = your end-to-end-encrypted direct links — even across different nodes.
who can see what
nodes store nothing
Discovery nodes see only signaling metadata — peer IDs, display names, coarse location — and keep nothing at rest. Never your messages, files, or keys.
everything on your device
Messages live encrypted on your own device — including at rest. A built-in Data view shows you exactly what's stored, down to the byte.
no tracking
No ads, no analytics, no telemetry. The App Store privacy label is simply "Data Not Collected" — because there's nothing to collect.
