Short answer: Sessions Pro for Codex shows each ChatGPT account's Codex usage, the session (5-hour) and weekly limits and when each resets, in your Mac menu bar or Windows tray, and alerts you at 80% and 95%. It also runs every account as its own ChatGPT app, all signed in at once. For a quick look at one account, run /status in the Codex CLI, or open Codex's usage page in ChatGPT; both are free.
Free 1-hour preview once you've signed in to a profile. For macOS 14 or later, or Windows 10 or 11, with the ChatGPT desktop app.
Every account's Codex usage, in your menu bar.
Sessions Pro for Codex shows how much of each account's Codex session and weekly limit is used, and when each resets, in the menu bar on a Mac and the tray on Windows. The account in front shows how much it has left right next to its badge, and you get an alert at 80% and 95%, before an account runs out.
It also runs each account as its own ChatGPT app, all signed in at once, so you don't sign out to check another account. Try it free for an hour; after that it keeps showing one account's usage for free, and a $24.99 one-time license shows every account.

How do Codex usage limits work?
With a ChatGPT plan, Codex has two limits that run side by side: a session limit over a rolling 5-hour window, and a weekly limit. Each resets on its own schedule. Some plans show a single longer limit instead: a free account we checked on 23 October 2026 had one 30-day limit.
How fast you use them depends on the model and on how much work each task does: a long agent run with large files uses far more than a quick question. Codex in the ChatGPT app and the Codex CLI signed in to the same account draw from the same limits.
Where can you see how much is left?
- Codex CLI. Run
/statusin a Codex session. It shows the 5-hour and weekly limits with how much of each you've used and when each resets. - ChatGPT. Codex's usage page in ChatGPT shows the same limits for the account you're signed in to.
- The API. If you use Codex with an OpenAI API key, you pay per use: usage and spending are in the OpenAI platform dashboard, not in plan limits.
Both show the account you're signed in to. If you use more than one ChatGPT account for Codex, such as a work account and a personal one, you sign out, or open the other one somewhere else, to check it.

Each account's detail, one click away.
In the Sessions Pro for Codex window, every profile shows two thin bars for its session and week, and opening one shows the full numbers with the time left until each reset.
The numbers come from each profile's own ChatGPT sign-in and go only to ChatGPT; the sign-in itself is never changed. They're checked every minute while the menu or window is open, every 5 minutes otherwise.
Is it allowed to use several ChatGPT accounts?
The usage meter only shows numbers. It doesn't move you between accounts or do anything with them on its own. Sessions Pro for Codex runs the official ChatGPT app with accounts you already have, such as a work account and a personal one. It doesn't change how ChatGPT or Codex work, and OpenAI's terms apply to each account. Use it for accounts you're allowed to have, not to get around usage limits.
