What is Metrician?

Metrician is a free Chrome extension that shows ChatGPT, Claude, Grok, OpenCode Go and Ollama usage and reset times in one floating widget, with usage alerts, 28 skins and browser-only data storage.

Metrician is a Chrome extension that places a small floating widget on the page and shows how much of your AI allowance is left. It covers ChatGPT, Claude, Grok, OpenCode Go and Ollama, and displays usage together with reset times so the numbers are visible without opening each provider's settings page. The idea is borrowed from a car's fuel gauge: a quick look tells you whether there is enough left to keep working. The tool is aimed at people who rely on several AI services at once and run into rate limits or usage caps. Developers who mix a coding assistant with a chat subscription, and heavy users of local or hosted model plans, are the clearest fit. Setup does not require an account with Metrician itself. After installing from the Chrome Web Store, you pick a provider and the extension reads allowance information from provider pages where you are already signed in. In practice, each provider is shown as a ring that fills as usage grows. Hovering a ring reveals the reset time, the pace of consumption across the current cycle and how recent the reading is. Usage warnings can notify you when an allowance is about to renew or when consumption is running unusually fast, for example a large share used within a few minutes. The widget can be dragged anywhere, resized, switched between horizontal and vertical layouts, hidden on chosen sites or turned off. It ships with 28 skins, including Instrument Cluster, E-Ink Ledger, Split-Flap and 8-Bit Classic. On privacy, the readings are stored in the browser and the developer states that the extension sends no telemetry. That makes it a lighter option than dashboards or API billing monitors that require keys or cloud accounts. The trade-off is scope: it is limited to Chrome, works only with the listed providers (more are described as coming), and depends on what the provider pages expose. For anyone comparing usage trackers, it fits as a glanceable, local-first monitor rather than a full analytics platform.

How do you use Metrician?

1Install the extension
Open the Chrome Web Store listing from the Metrician homepage and add the extension to Chrome. No Metrician account is required.
2Sign in to your AI providers
Make sure you are signed in to ChatGPT, Claude, Grok, OpenCode Go or Ollama in the same browser, since Metrician reads usage from pages you are already signed in to.
3Connect a provider
Pick a provider in the extension so it can start reading your allowance. Each connected provider appears as a ring in the floating widget.
4Read the rings
Watch the rings fill as you use each service. Hover one to see the reset time, pace through the cycle and how fresh the reading is.
5Customize and enable alerts
Drag and resize the widget, choose a skin and layout, hide it on certain sites, and turn on usage warnings for upcoming resets or fast usage.
