One inbox on your desktop, too.
Every channel lands in the same Zo, sorted and searchable next to your files and automations, with its own persona and model per channel and allowed senders keeping it yours alone.
Same conversation, every screen.
Flip between Slack, iMessage, and Gmail and watch the same Zo answer in each one: attachments in each app's idiom, tone matched to the room, and the channel picked per conversation.
Messages that send themselves.
Briefings on your schedule
A 7 AM text with your calendar, the weather, and the three emails that need a reply.
Alerts the moment things happen
A new order, a filled form, a finished job: Zo starts the conversation on whichever channel you chose.
Replies with the work attached
Results come back as files, links, and charts in the thread, not a notification pointing somewhere else.
Messaging questions, answered.
Which channels can I use to talk to Zo?
Do I need the Zo app installed to message my Zo?
No. Channels work from the apps you already have: your Messages app, your email client, or your team chat. The Zo app is there when you want the full workspace, not a requirement for talking to your computer.
Can each channel have its own persona and model?
Yes. You can set a dedicated persona and choose which AI model responds per channel, so your email replies can run on a careful model with a formal voice while your texts stay quick and casual.
Who can message my Zo?
Only you, unless you say otherwise. Channels support allowed-sender lists, so your Zo answers your number and your chosen addresses and ignores everyone else.
Can Zo message me first?
Yes. Automations and scheduled agents can deliver briefings, alerts, and results over any connected channel, so the useful half of messaging is the messages you never had to ask for.
