White Noise
The private messenger you can start using in seconds. No phone number, no email.
With support from
Private messages.
Private groups.
Talk one to one or bring a group together. Every message is end-to-end encrypted with MLS, an open internet standard built for group chat. Only the people in the conversation can read it. Even White Noise can’t.
Why privacy mattersNo phone number.
No email.
Choose a name and start. White Noise doesn’t ask for a phone number, email address or real name. Create as many identities as you like: one for friends, one for work, a new one for people you’ve just met. You decide how you’re known.
All your AI
in a single app
An agent is just another contact. Seven work today: Hermes, OpenClaw, Codex, Claude Code, OpenCode, Pi and Goose. Run the connector next to your agent on a Mac or Linux computer, then message it from your phone. It sits in the same list as everyone else, and it’s useful before any of your friends join.
Connect your agentNo central server.
White Noise delivers messages through independent servers called relays. You choose which ones to use, and your identity and contacts stay yours when you change them. A conversation can use several relays, so others can keep carrying messages if one goes offline. You can even run your own.
We can’t lock you in.
White Noise is built on Marmot, an open messaging protocol anyone can build on without asking permission. That means other developers can create compatible apps, giving you more choice in how you connect.

Open standards.
White Noise’s code is open for anyone to inspect, improve, or build on. You don’t have to take our word for how it works. Developers can check the code, help fix problems, or use it to create something of their own. Open standards let others build apps that work with it.

Help make White Noise better. Share feedback, test new releases, translate, or contribute code and design. You don’t need to be a developer to make a difference. Simply telling us what feels confusing or what you wish worked better is a good place to start.
Get involvedFew things
you might ask.
Is White Noise free?
Yes. White Noise is free to download and open source. Running your own relay or choosing a paid relay service can have separate costs, but you do not need to run a server to get started.
Who pays for White Noise?
White Noise is supported by the Internet Privacy Foundation, a nonprofit, together with OpenSats, the Human Rights Foundation and And Other Stuff. It also accepts donations. The app shows no ads, and IPF does not sell personal information.
Support the projectWhich devices can I use?
White Noise is available on the App Store for iPhone and for Android. We recommend Zapstore for Android; Google Play and GitHub downloads are also available.
See download optionsWho can read my messages?
Messages are end-to-end encrypted for the participants in your conversation. White Noise and the relays carrying those messages cannot read their content. Participants can still copy or share what they receive, and someone with access to an unlocked or compromised device may be able to read messages on it.
Which agents can I connect?
MDK provides integrations for Hermes, OpenClaw, Codex, Claude Code, OpenCode, Pi, and Goose. Run the connector alongside your existing agent on a supported Mac or Linux computer, add its White Noise identity, and invite it to a conversation. The setup guide covers installation and which accounts are allowed to message it.
