QuotaScope — AI Usage for Codex & Claude

QuotaScope helps you monitor Codex and Claude usage limits directly in Chrome, analyze Codex usage, and receive notifications when your available quota is restored. Key features: • current Codex quota remaining and reset time; • Claude 5-hour, weekly, and model-specific limits, when available for the account; • detailed Codex statistics for a selected period, including credits, turns, threads, tokens, and active days; • interactive charts, peak dates, token distribution, and an activity heatmap; • local usage history; • system notifications when a limit resets or the available quota increases significantly; • statistics export in CSV and JSON formats; • PNG summary cards for sharing and publishing; • separate controls for Codex and Claude, refresh interval selection, and notification threshold settings; • interface available in Russian, English, Ukrainian, and Kazakh. Privacy QuotaScope runs in the browser and uses your existing signed-in sessions on chatgpt.com and claude.ai. The ChatGPT access token is not stored. Settings, sanitized usage metrics, and local history are stored only in chrome.storage.local and are not sent to the developer or third-party analytics services. You must be signed in to the corresponding service for QuotaScope to work. The availability of individual metrics depends on your subscription plan and the service response. Claude usage through Anthropic Console or an API key is not included in Claude web usage limits. QuotaScope is an independent project. It is not affiliated with, sponsored by, or endorsed by OpenAI or Anthropic.
