Metrician

Metrician is a Google Chrome browser extension specifically designed for real-time AI usage tracking. This tool acts as a centralized dashboard that allows users to monitor message limits and reset times across various language models. Its primary function is to prevent workflow interruptions caused by unexpectedly hitting usage limits by consolidating information from multiple providers into a single, discreet, and visual floating widget.

The application is compatible with the industry's leading services, including ChatGPT, Claude, Grok, OpenCode Go, and Ollama. Metrician works by reading usage data directly from the pages where the user is already logged in on their computer. Since it does not require an external account or additional registration, it facilitates immediate and secure integration. The user simply selects the provider, and the tool automatically extracts information from the active session.

The user interface features a system of visual rings that fill up as the available quota is consumed. Hovering over these elements reveals detailed technical information, such as the exact quota reset time, the current consumption rate relative to the time cycle, and the last data update. Additionally, Metrician stands out for its high level of functional customization:

• It features 28 skins or interchangeable visual themes, including retro, minimalist, and "E-Ink" styles.
• It allows users to drag and place the widget anywhere within the browser window.
• It offers options to adjust the size and configure selective visibility on specific websites.

One of its most practical features is AI usage alerts. The system generates preemptive notifications when an allocation is nearly exhausted or if the user is consuming credits faster than usual. This is essential for professionals who manage ChatGPT usage limits or Claude and need to plan their tasks without interruptions.

Regarding security, the tool prioritizes data privacy, as all information read from providers is stored locally in the browser. Metrician does not use telemetry or send data to external servers, ensuring that usage metrics remain within the user's local environment.

This solution is ideal for developers, content creators, and power users who work with multiple AI models simultaneously. By centralizing session limits and message quotas into a single view, it optimizes technological resource management and boosts productivity by eliminating the need to manually check account statuses on each platform.
