OpenAI Usage Monitor

Track Codex usage windows on your ChatGPT account.

Keep an EYE 👁️on your Codex usage directly from your browser. OpenAI Usage Monitor displays the Codex usage windows available for your signed-in ChatGPT account. Check your usage from the Chrome toolbar and open the extension for more details. WHAT YOU CAN SEE • Your used percentage in a color-coded toolbar badge. • The used and remaining percentages for your primary usage window. • The reset date and time, along with the time remaining. • Details of a second usage window, including its usage and reset time, when available for your account. • Your plan and the time of the most recent update, when available. The extension checks for updates approximately every two minutes. You can also refresh the information manually. GETTING STARTED 1. Install the extension and sign in to ChatGPT in the same browser. 2. Pin OpenAI Usage Monitor to your toolbar to keep the usage indicator visible. 3. Click the extension icon to see the available usage details. PRIVACY AND PERMISSIONS The extension uses your existing ChatGPT session to request usage information directly from chatgpt.com. It uses a temporary session token in memory for that request and stores the latest usage reading and errors locally in your browser. The extension does not ask for your password or send your usage data to the developer or third-party servers. IMPORTANT INFORMATION Available usage windows and values depend on your ChatGPT account and plan. The extension shows Codex usage data returned for your account; it does not show every ChatGPT model limit, paid API usage, token balances, or credit balances. The service used to retrieve this information may change, which could affect the extension’s operation. OpenAI Usage Monitor is an independent extension and is not an official OpenAI product.
