  AI Usage Monitor helps you check Cursor, Codex, and Claude usage from one compact Chrome toolbar popup.
  
  If you use multiple AI coding tools, checking each usage page separately can be time-consuming. This extension opens or reloads the official usage pages, reads the usage information shown on screen, and summarizes the latest status in one place.
  
  You can quickly check:
  • Usage for Cursor, Codex, and Claude
  • Reset timing
  • Remaining credits or usage limits
  • Provider-specific metrics
  • The latest stored snapshot from the toolbar popup
  
  Key features:
  • Compact popup next to the Chrome toolbar
  • Manual refresh
  • Pause / resume automatic background updates
  • Choose which providers appear in the popup
  • Drag-and-drop to reorder providers
  • Auto-refresh interval setting, from 1 to 120 minutes
  • Quick presets for refresh intervals
  • Provider icons and colored accent bars for easier recognition
  • Display language setting for the popup and options UI
  
  How it works:
  After installation, the extension opens or reloads the official usage pages for each supported service and reads the numbers displayed on those pages. If a target tab is already open, the extension reloads that tab to refresh the data. Tabs are not closed after collection.
  
  Click the toolbar icon anytime to open the popup and review the latest stored snapshot.
  
  Settings:
  From the Options page, you can show or hide each provider, reorder providers by dragging rows, set the auto-refresh interval, and choose the display language for the popup and settings UI.
  
  Data handling:
  Usage information is stored only in this browser. Nothing is sent to external servers, shared with third parties, or used for ads or analytics.
  
  Notes:
  You must be logged in to each service’s official usage page. If you are not logged in, or if the page does not render correctly, metrics may not be collected.
  
  If a service changes its page layout or wording, parsing may stop working until the extension is updated.

  AI Usage Monitor is a privacy-first Chrome extension for developers and AI power users who use multiple AI coding tools.
  
  It lets you check Cursor, Codex, Claude, and optional Devin usage from one compact Chrome toolbar popup — without sending your usage data to any external server.
  
  Instead of opening each provider’s usage page manually, you can quickly review your latest usage snapshot in one place.
  
  Supported providers:
  • Cursor
  • Codex
  • Claude
  • Devin, optional
  
  Key features:
  • Compact Chrome toolbar popup
  • Manual refresh
  • Optional automatic refresh
  • Pause / resume background updates
  • Choose which providers appear in the popup
  • Drag-and-drop provider ordering
  • Refresh interval setting from 1 to 120 minutes
  • Quick presets for refresh intervals
  • Provider icons and accent bars for easier recognition
  • Display language setting for the popup and options UI
  
  Privacy-first by design:
  • Usage data stays only in your browser
  • No external server
  • No ads
  • No third-party analytics
  • Only supported official usage pages are read
  • No page overlays or content modification
  
  Why permissions are needed:
  • tabs: to open or reload supported official usage pages
  • scripting: to read usage text already displayed on supported usage pages
  • storage: to save settings and latest usage snapshots locally in Chrome
  • alarms: to run optional automatic refresh
  • host permissions: limited to supported provider usage pages
  
  How it works:
  After installation, the extension opens or reloads the official usage pages for enabled services and reads the usage information shown on those pages.
  
  If a target tab is already open, the extension may reload that tab to refresh the data. Tabs are not closed after collection.
  
  The extension does not inject ads, toasts, or on-page overlays. It only reads usage text already shown on supported official pages and displays the latest snapshot in the toolbar popup.
  
  Optional Devin support:
  Devin is off by default. To enable it, open Options, enter your Devin organization slug, and save.
  
  Supported official usage pages:
  • cursor.com usage / spending pages
  • chatgpt.com Codex usage analytics pages
  • claude.ai usage settings pages
  • app.devin.ai organization usage settings pages, when Devin is enabled
  
  Notes:
  You must be signed in to each service’s official usage page. If you are not logged in, or if the page does not render correctly, metrics may not be collected.
  
  If a service changes its page layout or wording, parsing may stop working until the extension is updated.
