One simple app for every agent you use.

Every thread in one sidebar.

Projects and threads from every provider live in one Cursor-style sidebar. Each thread shows whether it's working, done, or waiting on you.

Switch agents without switching apps.

Change the provider or model in the middle of a thread. Pin your favorite models and cycle through them from the keyboard.

From thread to pull request.

Give a thread its own worktree and branch. Review the diff, then commit, push, and open a pull request in one step.

Your inbox, on your phone.

Pair your iPhone with a QR code. The Inbox shows what's running and what needs you, so you can reply and send the next instruction from anywhere.

Connect your devices with Tailscale.

Tailscale puts your Mac and iPhone on a private network, so the app can reach your Mac from anywhere without exposing it to the internet.

  1. Install Tailscale on your Mac and iPhone and sign in to the same account.
  2. In the Tailscale admin console, turn on MagicDNS and HTTPS certificates under DNS.
  3. In Control Plane on your Mac, open Settings → Connections and turn on Tailscale HTTPS.
  4. Create a pairing link on the same page and scan its QR code with the Control Plane iPhone app.

The same steps connect another Mac or a browser on your tailnet.

Why I built it.

I build with agents from several subscriptions every day. The apps I enjoy most are simple: a sidebar, a thread, a diff. I wanted that feel in one place, working with every subscription I already pay for.

The T3 team has built a great platform. I've taken the interface in a direction that fits how I work: a Cursor-style sidebar, an inbox on mobile, and shortcuts for the views I open most.
