usage_monitor：在系统托盘实时查看 Claude、Codex、Grok 与 9Router 配额

🖥️ usage_monitor - Your AI Usage Dashboard, Live

🚀 What Is This?

usage_monitor is a small program that lives in your computer's system tray (the area near your clock). It shows you, in real time, how much of your AI service quotas you've used. It works with Claude, Codex, Grok, and 9Router—all in one place.

Think of it as a fuel gauge for your AI tools. No more guessing or logging into websites to check. Just glance at your tray, and you know exactly where you stand.

✨ Key Features

Live Quota Tracking – See your usage numbers update automatically as you work.
Works with 4 Services – Claude, Codex, Grok, and 9Router are all supported.
No API Keys Needed – The app reads your existing CLI logins. If you already use these tools from your terminal, you're ready to go.
Sits Quietly in Your Tray – It runs in the background, out of your way, until you need it.
Cross-Platform – Available for Windows, macOS, and Linux.

📥 How to Download and Install (Windows)

Follow these simple steps. You'll be up and running in under two minutes.

Step 1: Visit the Download Page

Click this button to go to the official download page:

Visit this link to download the application.

Step 2: Find the Latest Version

On that page, you'll see a list of releases. Look for the one with the highest version number (like v1.2.0). Click on it to expand the download options.

Step 3: Download the Windows Installer

Look for a file that ends with .exe. It might be named something like usage_monitor_setup.exe or usage_monitor_1.2.0_x64.exe. Click that file to start downloading.

Step 4: Run the Installer

Once the download finishes, double-click the .exe file you downloaded. Your computer might show a blue "Windows protected your PC" popup. If it does, click "More info" and then "Run anyway". This is normal for new apps from independent developers.

Step 5: Follow the Setup Wizard

A simple setup window will appear. Just click "Next" a few times, then "Install". When it's done, click "Finish".

Step 6: Launch the App

After installation, you'll see the usage_monitor icon in your system tray (bottom-right corner of your screen, near the clock). If you don't see it, click the small upward arrow to show hidden icons. That's it—you're done!

🖱️ How to Use

Using usage_monitor is as simple as it gets:

Just look at your tray – The icon shows a quick summary of your total usage.
Hover over the icon – A tooltip appears with a breakdown for each service.
Click the icon – A small window opens with detailed numbers for Claude, Codex, Grok, and 9Router.
Right-click the icon – You'll see options like "Refresh Now" and "Exit".

There are no settings to configure. If you can use the command line for these AI tools, usage_monitor automatically picks up your login and starts tracking.

❓ Frequently Asked Questions

Do I need to pay for this?

No. usage_monitor is completely free and open-source.

Is my data safe?

Yes. The app runs entirely on your computer. It doesn't send your usage data anywhere. It only reads local login files to know who you are.

Which services exactly are supported?

The app tracks quotas for:

Claude (Anthropic's AI assistant)
Codex (OpenAI's coding tool)
Grok (xAI's chatbot)
9Router (a network routing service)

What if I don't use all four services?

No problem. usage_monitor only shows the services you actually have logins for. If you only use Claude, you'll only see Claude's data.

Does it work on Mac or Linux?

Yes. While this guide focuses on Windows, the app also runs on macOS and Linux. The download page has versions for those systems too.

I'm not a programmer. Can I still use this?

Absolutely. This guide is written for you. The app is designed to be "set and forget." You don't need to write any code or understand technical concepts.

The app says "No login found." What does that mean?

This means the app couldn't find a CLI login for one of the services. This usually happens if you haven't used that service from your terminal/command line yet. To fix it, simply log in once using that service's normal command-line process, and usage_monitor will detect it next time.

🛠️ Troubleshooting

The app won't start

Make sure you have downloaded the correct version for your system (64-bit vs 32-bit).
Try right-clicking the installer and selecting "Run as administrator."
Restart your computer and try again.

The tray icon is missing

Click the upward arrow (^) in the taskbar to see hidden icons.
If it's still not there, open the Start menu, type "usage_monitor," and click the app to launch it manually.

Usage numbers look wrong

Right-click the tray icon and select "Refresh Now."
Make sure you're logged into the respective CLI tools.
Wait a minute and refresh again. Some services update slowly.

I get a "missing DLL" error

This is rare but can happen. Visit the download page and look for a file called vcredist_x64.exe or similar. Download and run it, then try installing usage_monitor again.

📝 System Requirements

To run usage_monitor smoothly, your computer should meet these minimum specs:

Operating System: Windows 10 or 11 (64-bit)
RAM: At least 2 GB
Storage: 50 MB of free space
Internet Connection: Required for live updates

These are modest requirements. Most computers from the last decade will run it without any issues.

🔄 Keeping the App Updated

usage_monitor checks for updates automatically. When a new version is available, you'll see a small notification in the tray. To update:

Click the notification.
The app will take you to the download page.
Download the new .exe file.
Run it. Your settings and logins will be preserved.

🗑️ Uninstalling usage_monitor

If you ever want to remove the app:

Open Settings (Windows key + I).
Go to Apps > Installed apps.
Search for "usage_monitor."
Click the three dots next to it and select Uninstall.
Follow the prompts.

That's it. No leftover files or registry clutter.
