A browser with a model beside it
Max Q is a research project: a native WebKit browser for the Mac, built to find out what a browser looks like when an AI model sits next to everything you read. Search from the address bar and Grok's answer comes first, streaming in with its sources named in the text, how long it worked, and what it cost. ⌘J opens Grok beside any page, to ask about that page, about all your open tabs, or about anything at all.
It runs on your own keys, billed to your own accounts and kept in the macOS Keychain. There is no server, no analytics and no telemetry, and Settings lists everything that is sent where.
An agent that asks first
Agent mode lets Grok do a task in a tab while you watch: it reads, clicks, types and scrolls, with a Stop button always in reach. The dangerous parts are decided in code, not left to the model. Clicks that spend money, delete something or close an account are caught, in English and in French, and wait for your yes. Password, card and one-time code fields are refused outright, and Max Q does not even show what the model meant to type into them. Banks, payments, password managers and account pages are off limits altogether.
It also keeps track of where its instructions could have come from. Until it has read a page, everything it knows came from you. Once it has, that page could be steering it, so opening a new site needs your yes unless you named it or the page links to it.
Reading Grokipedia like a browser does
The Grokipedia reader rebuilds articles natively from the public pages, never from the API that robots.txt asks visitors to stay out of, with contents that follow your place and numbered sources. Finding the right article goes through gated steps, and a typo may only be corrected by one letter in five, two at most, so a short word like “mars” can never become “bars”. A wrong card is worse than no card.
Every answer shows its price
Every Grok answer shows what it cost, read from the API's own accounting. Max Q keeps daily and monthly totals per feature and can stop at a limit you set. Research runs on a real budget: before each step it adds up what has been spent, what the step will cost and what the final report will take, and skips whatever would go over.
Work that should cost nothing stays on the Mac. Where Apple's on-device model is available, it groups tabs, summarises pages and decides whether a search is worth a paid answer at all, so nobody pays Grok to answer “weather”.
What it is not
There is no app to download and no release planned. Max Q is source code to read, build and learn from: 141 Swift files, 173 tests, English and French throughout, one dependency. Passkeys do not work in a copy built from source, because Apple grants that ability only to browsers it has approved. It is not affiliated with SpaceXAI, X or Grok.
