Installer & Setup

Requirements // Before You Install

Runs comfortably on a normal laptop.

A modern CPU with 8GB or more of RAM is recommended — a base model Mac Mini runs it easily

An NVIDIA card with CUDA support speeds things up significantly, but isn't required

The local model runs via llama.cpp — private, free, no API limits

Cloud models are optional and configurable from Settings > Models whenever a task needs more power

What you get on install

Systems	12 specialist systems, one interface
Guides	23 comprehensive guides bundled in-app
Workflows	70+ built-in workflow packs
Mobile	Built-in secure tunnel — access from your phone

Mobile // Your PC is the Server

Scan a QR code. Your AI is on your phone.

Celestos includes a built-in secure tunnel that wakes up the moment you start the app. A QR code prints straight in the terminal — scan it with your phone camera and you are in. No account, no pairing, no separate app to install.

A mobile-optimised Orb interface appears at a shareable HTTPS link

Microphone works — voice input is fully supported over the secure tunnel

Your computer stays the private backend — nothing routes through a third-party server

Tunnel launches automatically on startup if the tunneling tool is installed

How it works

Step 1 — Start Celestos on your Mac or PC as usual

Step 2 — A QR code appears in the terminal window automatically

Step 3 — Scan with your phone. The mobile Orb loads instantly in your browser

Step 4 — Speak or type. Responses stream back from your local engine
