Voice and mobile

Your desktop team on your phone, coming soon

The Brainwrite companion app, coming soon for iPhone and Android, is a window onto the Brainwrite running on your Mac. You pair it with a QR code, then read and send messages, answer approvals and questions, and follow live work. Your Mac stays the only machine that runs your bots and holds their credentials, chats and computers.

How it works

How Mobile companion works.

01
Open a pairing window
On your Mac, Brainwrite opens a two-minute pairing window with a QR code and a six-digit fallback code.
02
Pair the phone
Scan the code or type the six digits. The phone gets its own per-device token, and your Mac stores only a digest of it.
03
Choose how to connect
On the same Wi-Fi the phone finds your Mac directly. Away from home, use Tailscale on both devices or an optional hosted HTTPS address.
04
Keep your Mac reachable
Settings → Remote access has Keep this computer awake, off by default, so the phone can reach your Mac while you are away.

Good to know

The details.

What it is built to do

List bots and groups, read and send messages, interrupt work, answer approvals and questions, search, and follow live updates.

Default-deny by design

The phone can reach only an allowlist of routes. Provider keys, pairing admin, Local VM lifecycle, webhook secrets and team import or export stay desktop-only.

Grants are read-only

The phone shows each bot's connected-app grants but can never change them. Editing happens on the computer.

Hosted HTTPS without your chats

For the hosted address, Brainwrite's account service stores only which account and computer it belongs to, never your chats.

Revoke a lost phone

Revoking the device from desktop Settings invalidates its future requests.

Android control over USB, today

Separate from the companion app, a bot can already operate a USB-connected Android phone through the Phone Harness skill.

The edges, plainly

The iPhone and Android companion apps are not available yet. They are coming soon.
Your Mac must stay on, awake and running Brainwrite. A sleeping Mac cannot be reached, even over hosted HTTPS.
Secrets cannot be entered from a phone; the card asks you to finish on the computer that runs your bots.
Alerts arrive while the app is connected; a fully closed iPhone app cannot be woken without a future push relay.

FAQ

Questions about Mobile companion

Is there a Brainwrite app for iPhone or Android?

Not yet. Companion apps for iPhone and Android are coming soon; Brainwrite runs on macOS today. The companion pairs with the Brainwrite on your Mac, which keeps running your bots and holding their credentials and chats. If you need bots working while your Mac is off, Brainwrite Cloud covers that.

Will the mobile app run AI agents on my phone?

No. The companion is a window onto the Brainwrite running on your Mac. Your Mac stays the only machine that runs your bots and keeps their credentials, chats and computers. The phone sends messages and answers approvals; the work happens on the Mac.

How will the companion app reach my Mac when I am away from home?

On the same Wi-Fi it finds your Mac directly. Away from home you can use Tailscale on both devices, or sign in by email on the desktop to get a private hosted HTTPS address. In every case your Mac must be on, awake and running Brainwrite.

Can an AI agent control an Android phone today?

Yes, over USB. That is separate from the coming companion app. Brainwrite's Phone Harness skill lets a supported bot inspect the screen, open apps, tap, type, swipe and take screenshots on a USB-connected Android device with USB debugging turned on.
