Metrician is a Chrome extension that helps users monitor their AI usage across multiple providers from a single floating widget. It tracks services including ChatGPT, Claude, Grok, OpenCode Go, and Ollama, displaying current usage, remaining allowances, reset times, and usage pace. Users can receive alerts when an allowance is close to resetting or when their usage is increasing unusually quickly. The widget can be moved, resized, customized with different skins, hidden on specific websites, or disabled. Metrician reads usage information from provider pages that users are already signed into and stores the readings locally in Chrome. Its focus on monitoring AI development and coding services makes it particularly useful for developers who work across multiple AI tools.
