Messaging
1:1, channels, threads, reactions. End-to-end encrypted by default. Post-quantum upgrade path ready.
DIDComm v2Vilko is end-to-end encrypted team messaging built on DIDComm v2. Every identity is cryptographically verified. Keys live on your device. Sovereign deployment is a checkbox, not a sales cycle.
Messaging, calls, calendar, tasks, and files — built on a single encrypted protocol. One app for regulated teams that can't risk a breach.
1:1, channels, threads, reactions. End-to-end encrypted by default. Post-quantum upgrade path ready.
DIDComm v2Voice and video up to 50 participants. Media streams are P2P — Vilko never sees or hears a call.
WebRTC · P2PInvites delivered over DIDComm, not email. Time polls, signed RSVPs, cryptographic delegation.
Signed invitesKanban board linked to messages and calendar. Create a task from any message with one click.
Workspace-wide100 MB free, 1 GB paid, encrypted before upload. Preview PDFs, images, code, and video inline.
Client-encryptedAudit logs, eDiscovery, data retention, SSO. Self-hosted or sovereign deployment available.
ComplianceYour device holds the keys. The relay forwards ciphertext it cannot decrypt. The directory only knows which email maps to which public DID.
Each device generates its own keypair in a secure enclave. Private keys never leave. Messages encrypt before they hit the wire with X25519 + XC20P.
Our relay stores encrypted blobs and forwards them. It cannot read content, resolve senders, or reconstruct history. It is protocol_coordinate_mediation, nothing more.
Email maps to did:peer. Verifiable credentials back the “Verified” badge. Federate it, self-host it, or run it inside your own sovereign cloud.
We show our work. Where Slack, Teams, and Signal differ from us — and why a regulated team can't just “use Signal for work.”
