Setup

Three steps on each device.

01

Join the Tailnet

Install Tailscale and sign in to the same approved network on the PC, laptop, or phone.

02

Install T4 RAG

Use a verified installer above. On Android, approve installation from this trusted portal when prompted.

03

Open and pair

Open the private cloud, pair the client, then choose a live session to watch, control, or continue.

PC or laptop
  1. Connect Tailscale.
  2. Install the EXE matching your architecture.
  3. Open the private cloud and complete pairing.
  4. Use Watch or Take control on a session.
Android
  1. Connect the Tailscale Android app.
  2. Download the signed APK.
  3. Allow this one APK installation, then disable the permission again.
  4. Pair the app and enable notifications.
Private cloud
  1. The VPS remains the default always-on worker.
  2. Your devices are controllers; closing them does not stop VPS work.
  3. Use Git-backed handoff only when execution must move to another machine.

Supply-chain integrity

Trust the signature,
not just the filename.

Desktop releases require the signed manifest. Internal Android builds may be published without an APK signature, but only from this same-origin portal with an explicit SHA-256 checksum.

Compare the displayed artifact checksum before running an installer. Android may warn that the internal APK is from outside the Play Store; only install it when its checksum matches this page.
