Metricito Talk · In development

Chat, calls and meetings for your team, with no company server in the middle.

Talk is our alternative to Microsoft Teams. Messages, calls, screen shares and files go straight from device to device, end-to-end encrypted. The only server signs people in and keeps the member list. It never sees what you say.

The everyday parts of Teams

What Talk is being built to do.

Chat and channels

Trials

One-to-one and group conversations, with channels for teams and projects.

Files

Trials

Send files directly to colleagues, encrypted from your device to theirs.

Voice and video calls

Planned

Calls go direct between devices. Meetings of six or more use one participant's device, or your office's Talk Box, to pass on streams it cannot read.

Meetings and screen sharing

Planned

Meetings for about 25 people with video, with invitations through Calendar.

Presence

Planned

Available, busy or away, shared only with the people in your organisation.

Notes and Tasks

Planned

Shared notes and task lists that sync over the same encrypted connections.

How it works

Device to device first. Helpers only when needed, and they are blind.

Each device connects directly to the others. When a home router or a mobile network blocks a direct path, an encrypted relay passes the data on without being able to read it. Your organisation chooses its relays, and the defaults run on European hosts.

Groups use MLS, the IETF standard for group end-to-end encryption (RFC 9420). Every message, file and call is encrypted on your device and decrypted only on the devices of the people in the conversation.

Three keys stop anyone from adding a silent device to your account. Your organisation's root key stays offline, your own account key signs your devices, and the server can only list what those keys have signed.

What the server sees

A short, published list, and nothing else.

Stores	Your organisation's public key; each person's name, optional work email and public key; each device's certificate and relay address; the list of removed devices
Never receives	Messages, files, call records, contact lists, group membership or presence
Runs on	One small service in the EU that can move host with a DNS change

Talk is in early trials. The code has not been audited and must not carry real conversations yet.
