Dittu

Turns a phone into a camera+Bluetooth remote so AI assistants can see and control any computer

Documentation

Dittu MCP Server

Dittu turns a phone into the eyes and hands of an AI assistant. Stand the phone on a tripod facing a monitor — the camera reads the screen, Bluetooth pairs as a real mouse and keyboard. No software to install on the target computer, no remote-desktop setup.

Why a camera instead of screen-sharing?

Because it works on any computer — no software to install, no permissions to configure, no remote-desktop setup. If the monitor is in front of the phone, an AI assistant can see it and control it.
