What changed in Grux 3.0?

Grux 3.0, released on 29 September 2026, changes two things. What you see: the sidebar is gone, and Grux opens on one Command Panel with a single input, a Now list of what needs you and the Optimize Grux card. Anything you open, Chat, Today, Settings or Mail, slides in as one pane beside it. What changed underneath: every small judgment Grux makes for you, whether a message was meant for it, whether a mail needs you, whether a command is dangerous, now goes through one decision engine that you can see and tune on a single Tuning page. A command you say outright is decided on your Mac in about a millisecond, with no network. Only you answer a workflow's question, and a dry run changes nothing outside Grux. The public repository runs 3878 tests on every change.

What you will notice first

• One Command Panel. One input, the Now list and Optimize Grux. Pages open as one pane beside the panel and close back down. The old sidebar stays for one release under Settings, General, Shell.
• Only you answer a workflow's question. A waiting workflow takes its answer from a message you send after it asked, in a word it asked for. An agent's message never answers it.
• Dry runs change nothing. No tool call, command, webhook, banner or phone push leaves Grux, and every line it says starts with "Dry run".
• First run is one question. "What do you want to do with Grux?" Setup is built from your answer, one thing at a time.
• Tuning. One page for how sure Grux must be before acting, when it may interrupt, what it spends, what it remembers and what always asks first.
• It stops asking permission to do nothing. More than half of its 116 tools had no safety classification, so reading a list of files waited for you. Now only the tools that change something ask.

Speed, said plainly

Deciding what you meant used to take a network round trip of over a third of a second. It now happens on your Mac in about a millisecond. End to end, a spoken command reaches execution in about 1.5 seconds, down from 3.1. The target was 0.6 seconds and 3.0 did not reach it: transcription has a floor of about three quarters of a second, and Grux waits out a short pause before acting. Getting lower needs recognition that runs while you are still speaking, which is planned for 3.1.

Two things that were wrong and are fixed

• Grux used to claim that listening makes music and video sound tinny. It was measured, it was never true, and the claim is gone. What listening really did was take the microphone from other apps that were recording, and that is fixed.
• Grux could lose its audio feed mid-session and still report itself as listening. It now notices within seconds.
