§ 01what it does

Your agents, from your phone.

See every agent
every agent on your Mac in one list, the ones that need you first, with the real question they're asking.
Answer a prompt
answer a permission prompt with the key bar, or type a reply.
Watch a terminal
open any pane and watch its terminal live, exactly as it looks on the Mac. type into it.
Message an agent
send a message to any agent from your phone, with a photo attached if it helps — a screenshot of the bug, a sketch of the layout.
Start a workspace
start a new workspace from a prompt. the Mac makes the git worktree and the agent starts there.
Capture on the Board
capture cards on the Board from your phone.
§ 02requirements

What you need.

ON THE MAC
Thaytool for Mac 0.99 or later
macOS 26, Apple silicon, with Settings › Mobile › "Allow phone connections" turned on
IPHONE & IPAD
iOS 16.4 or later
ANDROID
Android 7.0 or later
§ 03set up

Pair your phone with your Mac.

  1. 01
    turn it on
    on the Mac, open Settings › Mobile and turn on "Allow phone connections". it is off by default: nothing listens until you turn it on.
  2. 02
    show the QR code
    in Settings › Mobile, click "Show QR code".
  3. 03
    scan it
    point your phone's camera at the code: with the app installed, the phone opens it and pairs. or, in the app, tap "Pair with your Mac" and scan the code there.
  • no app yet? the same code opens a page that says how to get it. on iPhone and iPad, thaytool mobile is in public beta on TestFlight; Android is coming soon to Google Play.
  • the code works once and expires after 10 minutes.
  • can't scan? on the Mac choose "Copy code", then in the app tap "Enter code instead" and paste it.
  • the phone and the Mac need to be on the same Wi-Fi network for pairing.
§ 04away from home

Away from home, use Tailscale.

install Tailscale on the Mac and on the phone, and sign in to the same tailnet. the app reaches the Mac through its Tailscale address automatically.

§ 05demo

No Mac handy? Try the demo.

the welcome screen's "Try the demo" opens a sample Mac with agents at work.

§ 06security

Straight to your Mac, end-to-end encrypted.

Straight to your Mac
the phone connects straight to your Mac. there is no thaytool server in between.
No account, nothing collected
there is no account to create, and the app collects nothing.
End-to-end encrypted
every connection uses X25519 key agreement, an Ed25519-signed handshake and ChaCha20-Poly1305.
Your Mac is pinned
when you pair, the phone pins your Mac's identity key, so another computer can't pretend to be it.
A key per phone
each phone gets its own key, kept in the iOS Keychain or the Android Keystore.
Cut off at any time
remove a phone in Settings › Mobile on the Mac and it is cut off immediately.

§ 07troubleshooting

When it won't connect, start here.

zsh — thaytool mobile
❯ thaytool faq "Can't reach your Mac"
check that the Mac is awake, that thaytool is running with "Allow phone connections" on, and that both devices are on the same network (or on Tailscale). guest, hotel and office Wi-Fi often keep devices apart: use Tailscale there. on iPhone, make sure Settings › Privacy & Security › Local Network › Thaytool is on. if the Mac's firewall asks, allow incoming connections for Thaytool.
❯ thaytool faq "That code expired"
a pairing code works once, for 10 minutes. on the Mac, click "New code" in Settings › Mobile and scan it again.
❯ thaytool faq "That code didn't work"
the camera read a QR code that isn't a thaytool pairing code. on the Mac, click "Show QR code" in Settings › Mobile and scan that one.
❯ thaytool faq "This phone was removed"
the phone was removed on the Mac (Settings › Mobile). pair it again: click "Show QR code" on the Mac, then tap "Pair with your Mac" in the app.
❯ thaytool faq "That doesn't look like your Mac"
the Mac that answered isn't the one you paired, or thaytool was reinstalled on it. in the app's Settings, remove the Mac, then pair again.
