AI Usage Monitor

读取 Cursor、Codex、Claude 的使用量页面，可选读取 Devin 使用量页面，并在扩展弹窗中显示指标。

AI Usage Monitor helps you check Cursor, Codex, Claude, and optionally Devin 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 • Optional Devin usage when enabled in Options (daily/weekly quota, on-demand balance, and other metrics shown on the official page) • 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 (e.g. English / Japanese) Optional Devin support: Devin is off by default. In Options, enable Devin, enter your organization slug (the name after /org/ in your Devin usage URL, for example: https://app.devin.ai/org/my-org/settings/usage), and save. The extension will open or reload that official usage page in the background, the same way it does for the other providers. Supported official usage pages only: • cursor.com (usage / spending) • chatgpt.com (Codex usage analytics) • claude.ai (usage settings) • app.devin.ai (organization usage settings, when Devin is enabled) How it works: After installation, the extension opens or reloads the official usage pages for each enabled 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. The extension does not inject ads, toasts, or on-page overlays on those sites—it only reads usage text already shown on the page and shows it in the toolbar popup. 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, choose the display language for the popup and settings UI, and configure Devin (show/hide and organization slug). 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 signed in to each service’s official usage page (including Devin when enabled). 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.
