Overview
Personal quota monitor for OpenCode Go, Claude, and ChatGPT/Codex.
AI Usage Quota Monitor Keep an eye on your AI subscription quotas without digging through settings pages. This lightweight extension shows your live usage for OpenCode Go, Claude, and ChatGPT/Codex, right from your toolbar. What you see - OpenCode Go — 5-hour, weekly, and monthly quota usage with reset times - Claude — current-session and weekly limits (plus model-specific and extra-usage rows when returned) - ChatGPT / Codex — weekly usage limit at a glance Every window shows the percentage used and exactly when your quota resets, so you always know whether that big task is safe to start. Features - Opens as its own standalone window — pin it and leave it on screen while you work - Auto-refreshes every minute; numbers update in place with no flicker - Clutter-free dark/light theme that follows your system - Optional macOS Dock launcher (see repo README) Privacy first - Everything runs locally in your browser — no analytics, no tracking, no external servers - Data is fetched only from opencode.ai, claude.ai, and chatgpt.com using your existing sign-in - Your OpenCode API key is stored only in your browser's extension storage and sent only to opencode.ai - No cookies or tokens from Claude/ChatGPT are ever copied into the extension Open source Free and open source (MIT) — built and maintained by Finch Technology Enterprise. Code: github.com/finch-technology-enterprise/ai-usage-monitor-chrome For the privacy questionnaire (the section above the description), answer: - Data collection: No user data is collected or transmitted - Permissions: cookies + host access to opencode.ai, claude.ai, chatgpt.com are required to fetch your logged-in quota data; used only for that purpose Note: Claude and ChatGPT usage endpoints are internal web APIs that may change without notice — worth a sentence in your review notes so reviewers know the extension reads the same data the provider's own site shows.
