5-hour and weekly bars
The bars use the same colors as the gauge and fill in darker as they fill up. On the right you see how long until the limit goes back to 0, like Resets in 2d 21h.
Claude and Codex limits left, one glance is all it takes
Aseul puts small round gauges next to the taskbar clock. The outer ring is weekly usage and the inner ring is 5-hour usage. The closer it goes from green to red, the closer you are to the limit.

Usage examples
Taskbar
Hover over the gauge to see numbers, click it for the status window, or right-click it for the menu.
Two rings tell you your usage
Each service gets its own circle.
Claude is on the left and Codex is on the right.
Only signed-in services are drawn, so if you use just one, you see just one circle.
Outer ring — weekly usage
Inner ring — 5-hour usage
Move the sliders to see the rings fill up.
- Each ring fills clockwise from 12 o'clock as you use it.
- The ring is split into five 20% sections colored green, lime, yellow, orange and red.
- Empty sections show in a faint color, so you can always see which color comes next.
- The arc is drawn a little longer so even very low usage stays visible. The exact numbers are in the status window.
- Green0–20%
- Lime20–40%
- Yellow40–60%
- Orange60–80%
- Red80–100%
Numbers on hover
Hover over the gauge and you get one line per service with 5-hour / weekly usage, like Claude : 35% / 72%.
Click for the status window
Click the gauge and the status window opens in the middle of the monitor the gauge is on.
It shows each service's usage and the time left until the next reset.
Close the window and the gauge stays on the taskbar and keeps updating.

Last 7 days chart
There is one bar per day, with today on the far right. Bar height is that day's weekly usage, and the darker top part is how much it went up that day. Hover over a bar to see the date and numbers.
When your sign-in expires
When your Claude Code or Codex sign-in expires, Sign-in required shows next to the name and the last values you got stay dimmed. Sign in again and it picks up at the next check.
The status window always uses a dark theme and does not add its own button to the taskbar.
Drawn to match your taskbar
On a light taskbar, the gauge sits on a black LED panel.
On a dark taskbar, only the rings are shown.
Switch themes and it follows right away.
The right end of the taskbar, drawn at actual size (100% scale).
The circles are the size of a tray icon, so they stay sharp on high-scaling monitors. If the taskbar height changes, such as with small taskbar buttons or a two-row taskbar, the gauge adjusts right away.
It reads from the sign-in you already have
No sign-up and no keys to enter.
There is no settings window either.
Your Claude Code and Codex sign-in, as is
Aseul uses the Claude Code and Codex sign-in on this PC to ask each service for your usage from time to time.
It leaves your sign-in alone
Aseul does not refresh your sign-in info, so Claude Code and Codex are not signed out because of it. When a sign-in expires, it tells you with Sign-in required.
History stays on this PC
The history used for the 7-day chart is saved in %LOCALAPPDATA%\Aseul. The installer version deletes it when you uninstall.
Only the services you use
Only signed-in services show up in the gauge and the status window. If neither is signed in, Aseul tells you so and exits.
Screens
The taskbar gauge, the status window and the right-click menu are the whole program.
The only setting you can change is Run at startup.
Usage, dates and times are examples.
How to
Getting started
Make sure you are signed in to Claude Code or Codex, then run Aseul. After a moment, a round gauge appears to the left of the notification area on the taskbar. For exact numbers, hover over the gauge or click it.
Checking what's left before a long task
Hover over the gauge to see 5-hour / weekly usage right away, like Claude : 35% / 72%. If weekly usage is close to the red section, you can plan around it, for example by holding big tasks until after the reset.
Finding out when your limit resets
Click the gauge to open the status window. To the right of the 5-hour and weekly bars you see the time left, like Resets in 2d 21h.
Seeing which days you used the most this week
In the status window, hover over the Claude or Codex entry to see the chart of the last 7 days. Hover over a bar to see the date, weekly usage and how much you used that day, like 10/15(Thu) · 56% (+12%).
Using only Claude or only Codex
There is nothing to set up. Only signed-in services get a circle in the gauge, and only they show in the status window.
Showing the gauge every time you turn on your PC
Right-click the gauge and check Run at startup. The installer version has it turned on already. To turn it off, click it again to uncheck it.
After signing in to Claude Code or Codex again
There is nothing to do in Aseul. At the next check it reads the new values and the gauge carries on. Until then, the status window shows the last values it got, dimmed.
Running it before you sign in
If you are not signed in to either Claude Code or Codex, Aseul shows "No signed-in AI found" and exits. Sign in to one of them and run it again.
Finding the status window again
Click the gauge and the window opens in the middle of the monitor the gauge is on. If it is already open, it comes to the front. Running Aseul again also opens the status window instead of starting a new copy.
Closing Aseul completely
Right-click the gauge, click Quit, then click Yes in the confirmation box. Closing the status window alone does not exit, and the gauge stays.

Frequently asked questions
Is it free?
Yes. It is freeware, with no sign-up or payment.
Which sign-in do I need?
For Claude, you need to be signed in to Claude Code with a Claude account. For Codex, you need to be signed in to Codex with a ChatGPT account. If you signed in to Codex with an API key, there is no usage info, so it does not show.
What is my sign-in info used for?
Only for asking that service for your usage. Aseul does not refresh or change your sign-in info.
How often does it update?
It checks on its own every few minutes and updates the gauge and the status window. There is no button to press.
The arc on the gauge looks longer than the number.
Very low usage would not be visible on the ring, so unless it is 0%, the arc is drawn a little longer. For the exact number, hover over the gauge or check the status window.
I see "Read failed" next to the name.
It means your internet connection dropped or the usage could not be fetched from the service. The gauge shows the last values it got and tries again at the next check.
Does it update itself?
No, it does not update itself. When it starts, it lets you know if a new version is out, and clicking Yes opens the download page.
How do I uninstall it?
For the installer version, uninstall it from Installed apps in Windows and your usage history is deleted too. For the portable version, turn off Run at startup, quit, delete the folder, and also delete %LOCALAPPDATA%\Aseul, where the history is kept.
