RUNS ON YOUR MACPOWERED BY CLAUDE AND CODEXNO SUBSCRIPTIONFREE RIGHT NOW

Bring your own model

Powered by Claude and Codex, on an account you control.

Maius runs Anthropic's Claude Code and OpenAI's Codex — and DeepSeek or xAI if you prefer. You choose whose model answers, and the vendor bills you directly.

We never bill you for usageWhatever model account you bring, the vendor bills you and we take nothing on top. Our price is the app itself.
Four ways in, and one of them is cheapAn Anthropic key, OpenAI's Codex, DeepSeek or xAI. A DeepSeek key costs cents for a day's work, and Codex comes with a ChatGPT plan you may already pay for.
We never see your key or your loginA key you paste stays on your own Mac, readable only by you. Signing in to Claude Code or Codex happens in the vendor's own app, never through ours.

Prices and billing

All prices include GST. Pay by card, Apple Pay or Google Pay. Model usage is billed to you by the vendor whose account you use — Anthropic, OpenAI, DeepSeek or xAI — and never by us. We do not resell anybody's model.

In short

What it is

Five agents share a room on your Mac. Each has its own job, memory and folder of work. They wander, sit when idle, and stir when they are thinking. Tap one to talk; send it across the room to talk to two at once.

Setting it up

Download, drag to Applications, open. It is powered by Claude and Codex, and you bring the model account: an Anthropic or OpenAI key, or DeepSeek or xAI. Usage is billed to you by that vendor, never by us. If you would rather sign in to Claude Code with a Claude plan, note that Anthropic requires Max or Pro — a free Claude account is refused.

What you get

One signed, notarised Mac app
Five agents, each with skills and a folder
Four worlds and 29 character looks
An avatar maker, or use a photo
Files, notes, web and GitHub connections
Phone access

Worth knowing

It needs your Mac awake. The agents run on your machine; when it sleeps, they stop.
