What isMilyonus Agent Ultra?
Milyonus Agent Ultra is a macOS app that brings your AI coding subscriptions together. It shows the live usage limits of Claude Code, Codex and Cursor in your Mac's notch, runs their agents side by side in one window, and moves a conversation to another account when one hits its limit.
It works through the official command-line tools with the accounts you already pay for, so it never resells model access. Agents edit a private copy of your project and you review every change. Milyonus Agent Ultra is made by Milyonus INC and is free during early access.

Questions,answered.
What is Milyonus Agent Ultra?
Milyonus Agent Ultra is a free macOS app for people who use AI coding agents. It puts the live usage limits of Claude Code, Codex and Cursor in the Mac's notch, runs their agents side by side in one window, and continues a conversation on another account when one reaches its limit. It is made by Milyonus INC.
Which AI coding tools does Milyonus support?
Claude Code, Codex (ChatGPT), Cursor and Antigravity. Milyonus drives their official command-line tools, and you can connect up to 5 accounts each for Claude Code, Codex and Cursor. A VS Code extension, the Agent Console, uses the same accounts and engine.
What happens when I hit a Claude Code or Codex usage limit?
The island shows each account's session and weekly usage with its reset time, and a notification warns you before a quota runs out. When an account does hit its limit, the conversation continues on another account of the same provider, or on any provider you allow.
Do I need my own AI subscriptions?
Yes. Milyonus drives the official CLIs (Claude Code, Codex, Cursor and Antigravity) with the accounts you already pay for. It doesn't resell model access.
Which Macs are supported?
Any Mac on macOS 14 Sonoma or later, Apple silicon or Intel. On Macs without a notch, the island hangs from the top of the screen.
How do quotas get read?
Directly from each provider with your local sign-in. Tokens are held in memory only during a request and never written to disk or logged.
Can an agent break my project?
Agents edit a private copy. You see every proposal as a diff and accept, reject or revert per file. Deleted files go to the Trash, and you're warned if a file changed on disk meanwhile.
Is there a VS Code version?
Yes. The Agent Console extension runs on the same engine as the Mac window, sharing accounts, the router and fallback.
Is Milyonus free?
Yes. Milyonus is completely free during early access, with every feature included and no card required. You only need the AI subscriptions you already use; those are billed by their providers, not by us.
How does the waitlist work?
Leave your e-mail and we'll send an invite with the download link as soon as your spot opens. We use the address for that invite and launch news only, and you can ask us to remove it any time at info@milyonus.com.
When is the Mac App Store version coming?
Soon. Until then, download the app from the download page. It updates the same way.
