AIGauge official site https://rayofray.com/extensions/aigauge/ AIGauge is a Chrome extension for checking your Claude (claude.ai) and Codex (ChatGPT) usage. 🛠 Built in Japan by an independent developer. The interface is available in Japanese and English, and so is support. 📊 Lists the percentage used and time until reset for each limit, so you notice before the cap. Per-model weekly limits are supported. 🖥 Works in the side panel and as a separate small window. The small window adapts to its size, so both services stay readable even when it is tiny. 🔒 How your data is handled Usage data and your account details for those services are never sent to any AIGauge server. No AIGauge account or email is required. For Codex, a short-lived access token and the selected account identifier are used only inside chatgpt.com to request that account's usage. They are never passed from the in-page function to the extension's service worker or UI, stored, logged, or sent to AIGauge's servers. Usage history stored on your device contains only the timestamp, the kind of limit, and the percentage used. Conversation content is never read. The PR slot that keeps AIGauge free counts impressions and clicks only, in a form that does not identify individuals. Details: https://rayofray.com/extensions/aigauge/privacy.html 💳 Pricing Free.
