Secure by default. Accessible by design.

An open source, decentralized messenger. Several interfaces, one identity — from power-user to anyone who just wants to stay in touch.

Today's messaging apps force trade-offs

Built for the platforms, not the people who use them.

  • Data monetized

    Your conversations feed their business model.

    Data monetized

    End-to-end encryption by default — the operator literally cannot read your messages, so there is nothing to monetize.

  • Encryption missing or optional

    Your messages stay readable by the operator. And by anyone who can ask.

    Encryption missing or optional

    Encryption is on by default and cannot be turned off. Even we cannot read your conversations.

  • Accessibility bolted on

    A regulatory checkbox. Seniors and people with disabilities left out by design.

    Accessibility bolted on

    Accessibility is co-designed from day one with seniors and people with disabilities, not bolted on at the end.

  • Intrusive ID checks

    ID cards, face scans, phone numbers — just to talk to the people you care about.

    Intrusive ID checks

    Sign up with a username and a passphrase. No phone number, no ID card, no face scan — ever.

  • Unilateral decisions

    Unexplained bans, rules rewritten without notice.

    Unilateral decisions

    Federated by design — you can host your own server with your own rules, and platform changes are debated in the open.

  • Data locked in

    Leaving the platform means losing everything.

    Data locked in

    Built on Matrix: take your account, contacts and history with you to any compatible client, anytime.

What CORAX.chat inverts

Decentralized, encrypted, portable. And no black box, ever.

  • Open source

    Open code, documented process. No black box.

    Concretely

    AGPLv3-licensed code, public roadmap, transparent governance backed by a French non-profit. Anyone can audit, fork or contribute.

  • End-to-end encrypted

    Encryption by default. Nobody can read your messages.

    Concretely

    Olm and Megolm protocols — the same battle-tested cryptography behind Element. Keys never leave your device.

  • Decentralized

    Built on Matrix. Federated, no single point of failure, self-hostable.

    Concretely

    Hundreds of independent servers already federate over Matrix. If one goes down, the network keeps running — and you can self-host yours.

  • Portable

    Switch clients without losing a thing. Your identity stays yours.

    Concretely

    Export your full history with one click and import it into another Matrix client. Your contacts, rooms and identity follow you.

  • Community-driven

    Decisions made with users, not handed down.

    Concretely

    Public RFCs, open issue tracker, non-profit assemblies — anyone can propose, debate or push back on a change.

  • Co-designed accessibility

    Designed from scratch with the people concerned, not for them.

    Concretely

    Screen-reader pass on every release, dyslexic-font option, high-contrast theme, and a keyboard-first interface.

An interface for each use

One protocol for everyone, an interface for each — designed with the people who'll use it.

  • For power-users

    Dense interface. Every feature within reach.

    An example

    Sarah, a tech lead, juggles 30+ rooms across federated workspaces — shortcuts, threads and bridges keep everything one keypress away.

  • For the everyday

    Familiar UX, no clutter.

    An example

    Marc messages his team and his family from the same app — a clean inbox, quick replies, no feature overload.

  • For staying in touch

    Clear, readable, designed for seniors.

    An example

    Anne, 72, calls her grandchildren with one tap — large text, simple layout, no notifications she didn't ask for.

  • For communicating without barriers

    Co-designed with people with disabilities.

    An example

    Léa navigates exclusively with a screen reader — every screen is labelled, every action announced, nothing relies on colour alone.
