Is Ekko another messenger I have to move people to?

No. Ekko is a layer over the apps you already use. Your chats stay exactly where they are, but the words inside them become unreadable to anyone but the person you wrote to.

What do Ekko's servers actually see?

Handles and public keys form the entire directory. Your private keys are generated and stay on your device, and your messages travel through your apps as sealed ciphertext, never through Ekko's servers.

Do I need an account?

Only if you want one. You can claim a handle so friends find your key automatically, or stay off the grid entirely and trade invites by hand. Both modes are supported equally.

What does post-quantum mean here?

Every message is sealed with a hybrid of X25519 and ML-KEM-768 with XChaCha20-Poly1305. This means anything recorded today stays unreadable even to a future quantum computer.

Which apps does Ekko work with?

Ekko works with Instagram, WhatsApp, Telegram, X, Messenger and more. It starts in your browser now and is expanding to phone keyboards next.

Overview

Screenshot of the Ekko homepage — What useekko.app looks like

Ekko is an independent privacy lab building post-quantum communication for the platforms people use today. It works as a layer over existing messengers like Instagram, WhatsApp, Telegram, X and others, sealing messages with encryption on your device so they remain unreadable to anyone but the recipient. Users can claim a handle so friends find their public key automatically, or stay completely anonymous and trade invites directly. Private keys are generated and stored only on your device, never uploaded to Ekko's servers. The product is currently in public alpha as a browser extension, with plans to expand to phone keyboards.
