Grux OS 1.2.1 · last checked 2026-09-13 · generated from the shipping release

Grux OS is a free, MIT licensed AI agent that runs as a native macOS app on your own machine. It has no account, no server and no subscription, so every question about it comes back to the same two facts: the software is yours to read, and the data never leaves your Mac unless you point it at a hosted model yourself. The pages below answer the questions people actually ask before installing something that can read their mail, watch their screen and run shell commands. Each one is written from the shipping source rather than from a marketing page, and each names the thing Grux OS does badly alongside the thing it does well. If an answer here disagrees with the repository, the repository is right and this page is a bug.

Every page below is generated from the shipping release and the public feature registry, so the version numbers, counts and capabilities on this site cannot drift from the app without the build failing.

Every answer

• What is Grux OS?Grux OS is a free, MIT licensed native macOS app that gives an AI agent your mail, calendar, meetings, screen and a shell it can undo. No account, no server.
• How do I run an AI assistant locally on a Mac?What local-first actually means for a Mac AI assistant, which parts of Grux OS run with nothing leaving the machine, and the one part that does not.
• Which local model will actually run on this Mac?How to work out which local LLM fits your Mac's memory before downloading it, and how Grux OS scores the fit from your real hardware.
• Can I get AI meeting notes without uploading the audio?How on-device meeting transcription works on macOS, why capturing both sides needs two permissions, and what Grux OS does with the recording.
• How do I let an AI agent run shell commands without losing work?Snapshot before you run, gate what matters, log everything. How Grux OS makes an agent's terminal session undoable on macOS.
• How do I give an AI agent access to my mail and calendar?Forwarding your inbox to a service is one answer. Reading it in place on your own Mac is a different one. What Grux OS connects to and what it needs.
• Which macOS permissions does an AI assistant need?Nine macOS permissions, what each one actually buys, and which ones you can refuse without losing anything. The full table from the shipping app.
• Is there an AI assistant with no account and no subscription?What free actually means when an app has no server: no account, no telemetry, no markup on model spend, and how to check each claim yourself.
• How do I stop an AI agent leaking my credentials to a model?Redaction before the prompt leaves, an SSRF policy for links the agent follows, and a published advisory record. The Swift package Grux OS runs on.
• Can a coding agent set up and drive a Mac app for me?An unattended command line with JSON on every read, a prompt-printing mode, and a read-only MCP bridge. How Grux OS is driven without a window.
