AI Quota Monitor — Usage Tracker for ChatGPT, Claude, Gemini & more

See how much of your AI subscriptions you have used: session, weekly and monthly limits, reset countdowns, badge and history.

Your AI subscriptions have limits: a five-hour session window, a weekly cap, a monthly pool of premium requests, a balance of credits. Each service shows them on its own usage page, and you have to open every one of them to know where you stand. AI Quota Monitor brings those numbers into one dashboard in the toolbar popup or in Chrome's side panel. It supports eleven services: the major chat assistants, the AI coding plans, and the developer consoles of the model providers. Each one is shown with the same figures its own usage page reports, updated every five minutes. HOW IT WORKS The extension reads each service through the login already in your browser. Switch a service on in settings and it asks for permission to that one site, nothing more. Two of the coding plans also accept the API key your coding tools already use, so their numbers stay fresh even when no tab of that site is open. There are no accounts and nothing to sign up for. WHAT YOU GET - Dashboard: one tile per service with its main usage windows and live reset countdowns. Click a tile for the full detail view with every window, per-model limits, plan and credits, and a strip to switch between services. - Toolbar badge: the fullest window across all your services, or one chosen service, as a number, a colour ring in ten percent steps, or both. - Notifications: one desktop notification per window and reset cycle when a limit crosses your threshold. - History: a local record of every refresh, with charts per window over 7, 30 or 90 days, peaks, daily pace, and a projection of when a window runs out, before it happens. - Side panel: the same dashboard docked next to your pages while you work. - Dark and light themes, one or two tile columns, and a custom order for your services. - Resets: some services hand out one-time usage-limit resets. The extension shows them, tells you what they restore and when they expire, and lets you spend one with a confirm step, so you never have to dig through a settings page to find it. PRIVATE BY DESIGN Everything is stored in this browser only. The extension talks to nothing but the services' own servers. It has no backend, no accounts and no analytics. Usage history never leaves your machine, and you can export it as CSV or JSON, or delete it, from settings. Service names and logos shown in the extension are trademarks of their respective owners and are used only to identify the services whose usage it displays. AI Quota Monitor is an independent project, not affiliated with or endorsed by any of them. - - - WHAT'S NEW IN 2.0.2 • Usage-limit resets: when a service offers a one-time reset, the detail view shows it with what it restores and when it expires, and a Reset button with a confirm step. A small ticket on the dashboard tile tells you one is waiting. • Usage history redesigned: one chart per window with a bar per day for the peak, a curve for the average, and exact numbers on hover. • Correct window labels on ChatGPT Pro plans after an upgrade from Plus. • A welcome page after installation that shows where to pin the icon.
