Message Matrix

Choose where to talk to your Matrix assistant, connect your messaging account, and continue conversations with the permissions and controls you choose.

Maintained by the Matrix OS team. Product instructions are updated with the supported workflow.

You can use Matrix in your browser or the desktop app, and reach your assistant through supported messaging apps. Choose the place that fits what you are doing: a quick question on your phone, a private Slack message, or a shared team discussion.

WhatsApp: your assistant on your phone

Message Matrix, connect your account, and ask for help with your day. Try planning an afternoon, drafting a reply, or asking about a calendar you have already connected in Matrix.

Follow the WhatsApp connection guide to get started, see examples, and learn how to disconnect.

Slack: personal help and team knowledge

Send the Matrix app a private message to reach your own assistant. In a connected company channel, mention Matrix to ask the shared assistant about information your team has made available.

Follow Slack and Company Brain to connect your account and learn which conversation to use.

Check availability

WhatsApp and the native Slack app are in early access. WhatsApp currently requires an invitation for an approved EEA account; Slack requires a participating workspace. Use your invitation or ask your workspace administrator before getting started.

What carries over?

Your personal messaging connection uses your own Matrix account and your assistant's existing permissions. To ask about a calendar, email, or another app, connect it in Matrix first and make sure your assistant can use it. See Connect Apps.

Slack and WhatsApp currently keep separate conversation histories. A company-channel conversation uses shared company context; it does not inherit your personal messages or connected accounts.

Open Matrix when you need to review work, read a longer answer, or handle an approval. Messaging access does not set up a new Matrix computer or add AI credit.

Other messaging apps

Telegram and Discord connections depend on what is enabled on your Matrix computer. Check the connection options available in your account or ask Matrix support for help.

If you want to read conversations from other messaging apps inside Matrix, see Messages. That is separate from messaging the Matrix assistant directly.
