Codex Usage Meter

Shows your ChatGPT Codex usage limits and credits at a glance. Unofficial, not affiliated with OpenAI.

Codex Usage Meter shows your ChatGPT Codex usage limits and credit balance right from your Chrome toolbar — no need to open the Codex usage dashboard. FEATURES • Toolbar badge shows remaining percentage (e.g. "87%") for your current rate-limit window • Popup shows details for both the 5-hour and weekly windows, credit balance, plan type, last updated time, and data source • Auto-refreshes on a configurable interval, and also refreshes whenever you have a chatgpt.com tab open • Supports Japanese and English, following your Chrome display language (or set manually) • A short welcome tab opens automatically on first install to explain how it works PRIVACY This extension never sends prompts, never calls the OpenAI API, never modifies ChatGPT, and never transmits your data to any external server. It only reads usage data already available in your authenticated chatgpt.com session. DISCLAIMER This is an unofficial, community-built extension. It is not affiliated with, endorsed by, or supported by OpenAI.
