What is Aseul?

Aseul is a Windows taskbar application that provides a straightforward way to monitor your Claude and Codex usage. It features a visually appealing dual-ring gauge that is displayed next to the taskbar clock. This gauge consists of two rings: the outer ring represents weekly usage, while the inner ring indicates usage over the past five hours. The color gradient from green to red alerts users to how close they are to the usage limit, encouraging proactive management of service consumption.

What Does it Do?

Aseul is user-friendly and efficient; you can hover over the gauge to reveal detailed usage statistics for both services, allowing quick glances at their usage rates. Clicking the gauge opens a more detailed status window on the same monitor, showing usage rates, time remaining until the next reset, and historical usage data. This feature enhances the overall user experience by making it simple to access important information without navigating away from their current tasks.

Simple Usage

The application is designed for ease of use and requires no sign-ups or configuration. Aseul automatically detects existing Claude Code and Codex sign-ins on the PC and periodically retrieves usage data. Importantly, it does not alter the user's sign-in credentials; thus, users remain signed in to their services. If a sign-in does expire, Aseul proactively notifies the user that a sign-in is required, ensuring minimal disruption to their workflow.

Seamlessly Adapts to Your Windows Taskbar Theme

Aseul's design adapts seamlessly to your Windows taskbar theme. Whether the taskbar is set to light or dark mode, Aseul adjusts the gauge's appearance accordingly. On a light taskbar, the gauge appears on a black LED panel, whereas on a dark taskbar, the rings are displayed without the background. This adaptability ensures that the application maintains an aesthetic consistency with the user's overall interface, contributing to a cohesive visual experience.

History Stored Locally

Lastly, Aseul securely stores usage history on the local machine, specifically within the %LOCALAPPDATA%\Aseul directory. This local storage is designed to protect user data and keeps only the last seven days of usage for chart visualization. Uninstalling the application deletes this history, ensuring users maintain control over their information. Aseul is committed to simplicity and efficiency, displaying only the services you are actively signed into, with a clear message if none are found (screenshot #1).

Geek Verdict

Aseul is a lightweight, incredibly useful taskbar utility for tracking AI API or subscription usage. It is a perfect fit for a wide range of environments, from bustling offices and cozy homes to busy government facilities and vibrant schools. Plus, it's designed for seamless redistribution across various platforms and locations, so you can easily share and utilize it wherever you need.
