AI Usage Limit Alerts

AI Usage Limit Alerts is a completely free browser extension with no ads and no subscription. It shows usage and reset timing for signed-in ChatGPT, Claude, Gemini, and Grok accounts in the popup and on each service page, and the toolbar badge shows the highest Claude utilization. The popup and in-page widgets follow the browser's light/dark theme automatically. The extension uses the current browser sign-in session to request data directly from each service domain. Usage results, notification state, Claude organization selection, and a Gemini request token are stored locally and are not sent to a developer server. A ChatGPT access token is used transiently in memory. The extension does not collect chat content, prompts, passwords, payment information, ad identifiers, or developer analytics. Key features: - Usage status for Claude, ChatGPT, Gemini, and Grok - Session and weekly limits, feature-based remaining counts, and model-based query limits - Reset timing visibility - Claude toolbar badge, popup, and in-page overlay - Local alerts at usage thresholds, exhaustion, and reset
