An AI agent that runs on your machine

Lux works where your work already is, so there is no uploading a codebase to somebody’s cloud first. Pay for the tokens you use, with no subscription. Built in Auckland, New Zealand.

Windows 10/11 · 64-bit · installs per-user, no admin

Your files, your terminal, your browser.

What actually runs on your machine

Lux is a desktop app, not a tab. It opens your files from disk, runs commands in a real shell, and drives a real Chrome window.

Nothing is copied anywhere to make that work. The agent reads the file on your disk, at the path you gave it, in the moment it needs it.

What does leave the machine is the conversation, sent to a model over an API, the same way any chat client works. That is the whole of it.

How a turn works

You describe the outcome. Lux plans a step, runs it, reads what came back, and decides the next one. It keeps going until the task is done or it needs you.

  • Every command it wants to run is shown before it runs
  • Every file it edits is a file you can open and diff
  • Stop it mid-turn and the work so far stays

The point is that you can follow along. An agent you cannot audit is a worse tool than one that asks.

What people use it for

failing fix green

Fixing what broke

Point it at a failing test or a stack trace. It reads the code around the failure, changes the thing that is wrong, and runs the test again to prove it.

Reading a codebase you did not write

Ask where something is handled and it searches the repo rather than guessing. You get the file and the line, not a paragraph about how projects like this are usually laid out.
